Side Effects & Adverse Reactions
XYLOCAINE INJECTIONS FOR INFILTRATION AND NERVE BLOCK SHOULD BE EMPLOYED ONLY BY CLINICIANS WHO ARE WELL VERSED IN DIAGNOSIS AND MANAGEMENT OF DOSE-RELATED TOXICITY AND OTHER ACUTE EMERGENCIES THAT MIGHT ARISE FROM THE BLOCK TO BE EMPLOYED AND THEN ONLY AFTER ENSURING THE IMMEDIATE AVAILABILITY OF OXYGEN, OTHER RESUSCITATIVE DRUGS, CARDIOPULMONARY EQUIPMENT AND THE PERSONNEL NEEDED FOR PROPER MANAGEMENT OF TOXIC REACTIONS AND RELATED EMERGENCIES (see also ADVERSE REACTIONS and PRECAUTIONS). DELAY IN PROPER MANAGEMENT OF DOSE-RELATED TOXICITY, UNDERVENTILATION FROM ANY CAUSE AND/OR ALTERED SENSITIVITY MAY LEAD TO THE DEVELOPMENT OF ACIDOSIS, CARDIAC ARREST AND, POSSIBLY, DEATH.
Intra-articular infusions of local anesthetics following arthroscopic and other surgical procedures is an unapproved use, and there have been post-marketing reports of chondrolysis in patients receiving such infusions. The majority of reported cases of chondrolysis have involved the shoulder joint; cases of gleno-humeral chondrolysis have been described in pediatric and adult patients following intra-articular infusions of local anesthetics with and without epinephrine for periods of 48 to 72 hours. There is insufficient information to determine whether shorter infusion periods are not associated with these findings. The time of onset of symptoms, such as joint pain, stiffness and loss of motion can be variable, but may begin as early as the 2nd month after surgery. Currently, there is no effective treatment for chondrolysis; patients who experienced chondrolysis have required additional diagnostic and therapeutic procedures and some required arthroplasty or shoulder replacement.
To avoid intravascular injection, aspiration should be performed before the local anesthetic solution is injected. The needle must be repositioned until no return of blood can be elicited by aspiration. Note, however, that the absence of blood in the syringe does not guarantee that intravascular injection has been avoided.
Local anesthetic solutions containing antimicrobial preservatives (eg, methylparaben) should not be used for epidural or spinal anesthesia because the safety of these agents has not been established with regard to intrathecal injection, either intentional or accidental.
Xylocaine with epinephrine solutions contain sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people.

Table 1 (Recommended Dosages) summarizes the recommended volumes and concentrations of Xylocaine Injection for various types of anesthetic procedures. The dosages suggested in this table are for normal healthy adults and refer to the use of epinephrine-free solutions. When larger volumes are required, only solutions containing epinephrine should be used except in those cases where vasopressor drugs may be contraindicated.
There have been adverse event reports of chondrolysis in patients receiving intra-articular infusions of local anesthetics following arthroscopic and other surgical procedures. Xylocaine is not approved for this use (see WARNINGS and DOSAGE AND ADMINISTRATION).
These recommended doses serve only as a guide to the amount of anesthetic required for most routine procedures. The actual volumes and concentrations to be used depend on a number of factors such as type and extent of surgical procedure, depth of anesthesia and degree of muscular relaxation required, duration of anesthesia required, and the physical condition of the patient. In all cases the lowest concentration and smallest dose that will produce the desired result should be given. Dosages should be reduced for children and for the elderly and debilitated patients and patients with cardiac and/or liver disease.
The onset of anesthesia, the duration of anesthesia and the degree of muscular relaxation are proportional to the volume and concentration (ie, total dose) of local anesthetic used. Thus, an increase in volume and concentration of Xylocaine Injection will decrease the onset of anesthesia, prolong the duration of anesthesia, provide a greater degree of muscular relaxation and increase the segmental spread of anesthesia. However, increasing the volume and concentration of Xylocaine Injection may result in a more profound fall in blood pressure when used in epidural anesthesia. Although the incidence of side effects with lidocaine HCl is quite low, caution should be exercised when employing large volumes and concentrations, since the incidence of side effects is directly proportional to the total dose of local anesthetic agent injected.
For intravenous regional anesthesia, only the 50 mL single dose vial containing Xylocaine (lidocaine HCl) 0.5% Injection should be used.
For epidural anesthesia, only the following dosage forms Xylocaine Injection are recommended:
1% without epinephrine 10 mL Plastic Ampule
1% without epinephrine 30 mL single dose solutions
1% with epinephrine 1:200,000 30 mL single dose solutions
1.5% without epinephrine 10 mL Plastic Ampule
1.5% without epinephrine 20 mL Plastic Ampule
1.5% with epinephrine 1:200,000 30 mL ampules, 30 mL single dose solutions
2% without epinephrine 10 mL Plastic Ampule
2% with epinephrine 1:200,000 20 mL ampules, 20 mL single dose solutions
Although these solutions are intended specifically for epidural anesthesia, they may also be used for infiltration and peripheral nerve block, provided they are employed as single dose units. These solutions contain no bacteriostatic agent.
In epidural anesthesia, the dosage varies with the number of dermatomes to be anesthetized (generally 2 to 3 mL of the indicated concentration per dermatome).
As a precaution against the adverse experience sometimes observed following unintentional penetration of the subarachnoid space, a test dose such as 2 to 3 mL of 1.5% lidocaine HCl should be administered at least 5 minutes prior to injecting the total volume required for a lumbar or caudal epidural block. The test dose should be repeated if the patient is moved in a manner that may have displaced the catheter. Epinephrine, if contained in the test dose (10 to 15 mcg have been suggested), may serve as a warning of unintentional intravascular injection. If injected into a blood vessel, this amount of epinephrine is likely to produce a transient “epinephrine response” within 45 seconds, consisting of an increase in heart rate and systolic blood pressure, circumoral pallor, palpitations and nervousness in the unsedated patient. The sedated patient may exhibit only a pulse rate increase of 20 or more beats per minute for 15 or more seconds. Patients on beta blockers may not manifest changes in heart rate, but blood pressure monitoring can detect an evanescent rise in systolic blood pressure. Adequate time should be allowed for onset of anesthesia after administration of each test dose. The rapid injection of a large volume of Xylocaine Injection through the catheter should be avoided, and, when feasible, fractional doses should be administered.
In the event of the known injection of a large volume of local anesthetic solution into the subarachnoid space, after suitable resuscitation and if the catheter is in place, consider attempting the recovery of drug by draining a moderate amount of cerebrospinal fluid (such as 10 mL) through the epidural catheter.

Adults Single Direct Intravenous Injection (bolus)The usual dose is 50 to 100 mg of lidocaine hydrochloride (0.70 to 1.4 mg/kg; 0.32 to 0.63 mg/lb) administered intravenously under ECG monitoring. This dose may be administered at the rate of approximately 25 to 50 mg/min (0.35 to 0.70 mg/kg/min; 0.16 to 0.32 mg/lb/min). Sufficient time should be allowed to enable a slow circulation to carry the drug to the site of action. If the initial injection of 50 to 100 mg does not produce a desired response, a second dose may be injected after 5 minutes. NO MORE THAN 200 TO 300 mg OF LIDOCAINE HYDROCHLORIDE SHOULD BE ADMINISTERED DURING A ONE HOUR PERIOD.
Continuous Intravenous InfusionFollowing bolus administration, intravenous infusions of Xylocaine may be initiated at the rate of 1 to 4 mg/min of lidocaine hydrochloride (0.014 to 0.057 mg/kg/min; 0.006 to 0.026 mg/lb/min). The rate of intravenous infusions should be reassessed as soon as the patient’s basic cardiac rhythm appears to be stable or at the earliest signs of toxicity. It should rarely be necessary to continue intravenous infusions for lidocaine for prolonged periods.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever the solution and container permit. Do not use if solution is discolored or cloudy.
PediatricControlled clinical studies in the pediatric population to establish dosing schedules have not been conducted.

When Xylocaine 2% Jelly is used concomitantly with other products containing lidocaine, the total dose contributed by all formulations must be kept in mind.
The dosage varies and depends upon the area to be anesthetized, vascularity of the tissues, individual tolerance, and the technique of anesthesia. The lowest dosage needed to provide effective anesthesia should be administered. Dosages should be reduced for children and for elderly and debilitated patients. Although the incidence of adverse effects with Xylocaine 2% Jelly is quite low, caution should be exercised, particularly when employing large amounts, since the incidence of adverse effects is directly proportional to the total dose of local anesthetic agent administered.
For Surface Anesthesia of the Male Adult Urethra
When using Xylocaine 2% Jelly 30 mL tubes, sterilize the plastic cone for 5 minutes in boiling water, cool, and attach to the tube. The cone may be gas sterilized or cold sterilized, as preferred. Slowly instill approximately 15 mL (300 mg of lidocaine HCl) into the urethra or until the patient has a feeling of tension. A penile clamp is then applied for several minutes at the corona. An additional dose of not more than 15 mL (300 mg) can be instilled for adequate anesthesia.
Prior to sounding or cystoscopy, a penile clamp should be applied for 5 to 10 minutes to obtain adequate anesthesia. A total dose of 30 mL (600 mg) is usually required to fill and dilate the male urethra.
Prior to catheterization, smaller volumes of 5 to 10 mL (100 to 200 mg) are usually adequate for lubrication.
For Surface Anesthesia of the Female Adult Urethra
When using Xylocaine 2% Jelly 30 mL tubes, sterilize the plastic cone for 5 minutes in boiling water, cool, and attach to the tube. The cone may be gas sterilized or cold sterilized, as preferred. Slowly instill 3 to 5 mL (60 to 100 mg of lidocaine HCl) of the jelly into the urethra. If desired, some jelly may be deposited on a cotton swab and introduced into the urethra. In order to obtain adequate anesthesia, several minutes should be allowed prior to performing urological procedures.
Lubrication for Endotracheal Intubation
Apply a moderate amount of jelly to the external surface of the endotracheal tube shortly before use. Care should be taken to avoid introducing the product into the lumen of the tube. Do not use the jelly to lubricate endotracheal stylettes. See WARNINGS and ADVERSE REACTIONS concerning rare reports of inner lumen occlusion. It is also recommended that use of endotracheal tubes with dried jelly on the external surface be avoided for lack of lubricating effect.

For epidural anesthesia, only the following dosage forms Xylocaine Injection are recommended:
1% without epinephrine 10 mL Polyamp DuoFit™
1% without epinephrine 30 mL single dose solutions
1% with epinephrine 30 mL single dose solutions
1:200,000
1.5% without epinephrine 10 mL Polyamp DuoFit™
1.5% without epinephrine 20 mL Polyamp DuoFit™
1.5% with epinephrine 30 mL ampules, 30 mL single dose solutions
1:200,000
2% without epinephrine 10 mL Polyamp DuoFit™
2% with epinephrine 20 mL ampules, 20 mL single dose solutions
1:200,000
Although these solutions are intended specifically for epidural anesthesia, they may also be used for infiltration and peripheral nerve
block, provided they are employed as single dose units. These solutions contain no bacteriostatic agent.
In epidural anesthesia, the dosage varies with the number of dermatomes to be anesthetized (generally 2 to 3 mL of the indicated
concentration per dermatome).
Caudal and Lumbar Epidural Block
As a precaution against the adverse experience sometimes observed following unintentional penetration of the subarachnoid space,
a test dose such as 2 to 3 mL of 1.5% lidocaine HCl should be administered at least 5 minutes prior to injecting the total volume
required for a lumbar or caudal epidural block. The test dose should be repeated if the patient is moved in a manner that may have
displaced the catheter. Epinephrine, if contained in the test dose (10 to 15 mcg have been suggested), may serve as a warning of
unintentional intravascular injection. If injected into a blood vessel, this amount of epinephrine is likely to produce a transient
page 7 of 27
“epinephrine response” within 45 seconds, consisting of an increase in heart rate and systolic blood pressure, circumoral pallor,
palpitations and nervousness in the unsedated patient. The sedated patient may exhibit only a pulse rate increase of 20 or more beats
per minute for 15 or more seconds. Patients on beta blockers may not manifest changes in heart rate, but blood pressure monitoring
can detect an evanescent rise in systolic blood pressure. Adequate time should be allowed for onset of anesthesia after administration
of each test dose. The rapid injection of a large volume of Xylocaine Injection through the catheter should be avoided, and, when
feasible, fractional doses should be administered.
In the event of the known injection of a large volume of local anesthetic solution into the subarachnoid space, after suitable
resuscitation and if the catheter is in place, consider attempting the recovery of drug by draining a moderate amount of cerebrospinal
fluid (such as 10 mL) through the epidural catheter.
MAXIMUM RECOMMENDED DOSAGES
Adults
For normal healthy adults, the individual maximum recommended dose of lidocaine HCl with epinephrine should not exceed 7 mg/kg
(3.5 mg/lb) of body weight, and in general it is recommended that the maximum total dose not exceed 500 mg. When used without
epinephrine the maximum individual dose should not exceed 4.5 mg/kg (2 mg/lb) of body weight, and in general it is recommended
that the maximum total dose does not exceed 300 mg. For continuous epidural or caudal anesthesia, the maximum recommended
dosage should not be administered at intervals of less than 90 minutes. When continuous lumbar or caudal epidural anesthesia is used
for non-obstetrical procedures, more drug may be administered if required to produce adequate anesthesia.
The maximum recommended dose per 90 minute period of lidocaine hydrochloride for paracervical block in obstetrical patients and
non-obstetrical patients is 200 mg total. One half of the total dose is usually administered to each side. Inject slowly, five minutes
between sides (see also discussion of paracervical block in PRECAUTIONS).
For intravenous regional anesthesia, the dose administered should not exceed 4 mg/kg in adults.
Children
It is difficult to recommend a maximum dose of any drug for children, since this varies as a function of age and weight. For children
over 3 years of age who have a normal lean body mass and normal body development, the maximum dose is determined by the
child’s age and weight. For example, in a child of 5 years weighing 50 lbs the dose of lidocaine HCl should not exceed 75 to 100 mg
(1.5 to 2 mg/lb). The use of even more dilute solutions (ie, 0.25 to 0.5%) and total dosages not to exceed 3 mg/kg (1.4 mg/lb) are
recommended for induction of intravenous regional anesthesia in children.
In order to guard against systemic toxicity, the lowest effective concentration and lowest effective dose should be used at all times. In
some cases it will be necessary to dilute available concentrations with 0.9% sodium chloride injection in order to obtain the required
final concentration.
NOTE: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever
the solution and container permit. The Injection is not to be used if its color is pinkish or darker than slightly yellow or if it contains a
precipitate.

Table 1 (Recommended Dosages) summarizes the recommended volumes and concentrations of Xylocaine Injection for various
“epinephrine response” within 45 seconds, consisting of an increase in heart rate and systolic blood pressure, circumoral pallor,
types of anesthetic procedures. The dosages suggested in this table are for normal healthy adults and refer to the use of epinephrinefree
solutions. When larger volumes are required, only solutions containing epinephrine should be used except in those cases where
vasopressor drugs may be contraindicated.
There have been adverse event reports of chondrolysis in patients receiving intra-articular infusions of local anesthetics following
arthroscopic and other surgical procedures. Xylocaine is not approved for this use (see WARNINGS and DOSAGE AND
ADMINISTRATION).
These recommended doses serve only as a guide to the amount of anesthetic required for most routine procedures. The actual volumes
and concentrations to be used depend on a number of factors such as type and extent of surgical procedure, depth of anesthesia and
degree of muscular relaxation required, duration of anesthesia required, and the physical condition of the patient. In all cases the
lowest concentration and smallest dose that will produce the desired result should be given. Dosages should be reduced for children
and for the elderly and debilitated patients and patients with cardiac and/or liver disease.
The onset of anesthesia, the duration of anesthesia and the degree of muscular relaxation are proportional to the volume and
concentration (ie, total dose) of local anesthetic used. Thus, an increase in volume and concentration of Xylocaine Injection will
decrease the onset of anesthesia, prolong the duration of anesthesia, provide a greater degree of muscular relaxation and increase
the segmental spread of anesthesia. However, increasing the volume and concentration of Xylocaine Injection may result in a more
profound fall in blood pressure when used in epidural anesthesia. Although the incidence of side effects with lidocaine HCl is quite
low, caution should be exercised when employing large volumes and concentrations, since the incidence of side effects is directly
proportional to the total dose of local anesthetic agent injected.
For intravenous regional anesthesia, only the 50 mL single dose vial containing Xylocaine (lidocaine HCl) 0.5% Injection should be
used.
Epidural Anesthesia
For epidural anesthesia, only the following dosage forms Xylocaine Injection are recommended:
1% without epinephrine 10 mL Polyamp DuoFit™
1% without epinephrine 30 mL single dose solutions

STERILIZATION, STORAGE AND TECHNICAL PROCEDURESDisinfecting agents containing heavy metals, which cause release of respective ions (mercury, zinc, copper, etc) should not be used for skin or mucous membrane disinfection as they have been related to incidents of swelling and edema. When chemical disinfection of multi-dose vials is desired, either isopropyl alcohol (91%) or ethyl alcohol (70%) is recommended. Many commercially available brands of rubbing alcohol, as well as solutions of ethyl alcohol not of USP grade, contain denaturants which are injurious to rubber and therefore are not to be used.
Dosage forms listed as Xylocaine-MPF indicate single dose solutions that are Methyl Paraben Free (MPF).

used.
Epidural Anesthesia
For epidural anesthesia, only the following dosage forms Xylocaine Injection are recommended:

block, provided they are employed as single dose units. These solutions contain no bacteriostatic agent.
In epidural anesthesia, the dosage varies with the number of dermatomes to be anesthetized (generally 2 to 3 mL of the indicated
concentration per dermatome).
Caudal and Lumbar Epidural Block
As a precaution against the adverse experience sometimes observed following unintentional penetration of the subarachnoid space,
a test dose such as 2 to 3 mL of 1.5% lidocaine HCl should be administered at least 5 minutes prior to injecting the total volume
required for a lumbar or caudal epidural block. The test dose should be repeated if the patient is moved in a manner that may have
displaced the catheter. Epinephrine, if contained in the test dose (10 to 15 mcg have been suggested), may serve as a warning of
unintentional intravascular injection. If injected into a blood vessel, this amount of epinephrine is likely to produce a transient
palpitations and nervousness in the unsedated patient. The sedated patient may exhibit only a pulse rate increase of 20 or more beats
per minute for 15 or more seconds. Patients on beta blockers may not manifest changes in heart rate, but blood pressure monitoring
can detect an evanescent rise in systolic blood pressure. Adequate time should be allowed for onset of anesthesia after administration
of each test dose. The rapid injection of a large volume of Xylocaine Injection through the catheter should be avoided, and, when
feasible, fractional doses should be administered.
In the event of the known injection of a large volume of local anesthetic solution into the subarachnoid space, after suitable
resuscitation and if the catheter is in place, consider attempting the recovery of drug by draining a moderate amount of cerebrospinal
fluid (such as 10 mL) through the epidural catheter.
MAXIMUM RECOMMENDED DOSAGES
Adults
For normal healthy adults, the individual maximum recommended dose of lidocaine HCl with epinephrine should not exceed 7 mg/kg
(3.5 mg/lb) of body weight, and in general it is recommended that the maximum total dose not exceed 500 mg. When used without
epinephrine the maximum individual dose should not exceed 4.5 mg/kg (2 mg/lb) of body weight, and in general it is recommended
that the maximum total dose does not exceed 300 mg. For continuous epidural or caudal anesthesia, the maximum recommended
dosage should not be administered at intervals of less than 90 minutes. When continuous lumbar or caudal epidural anesthesia is used
for non-obstetrical procedures, more drug may be administered if required to produce adequate anesthesia.
The maximum recommended dose per 90 minute period of lidocaine hydrochloride for paracervical block in obstetrical patients and
non-obstetrical patients is 200 mg total. One half of the total dose is usually administered to each side. Inject slowly, five minutes
between sides (see also discussion of paracervical block in PRECAUTIONS).
For intravenous regional anesthesia, the dose administered should not exceed 4 mg/kg in adults.
Children
It is difficult to recommend a maximum dose of any drug for children, since this varies as a function of age and weight. For children
over 3 years of age who have a normal lean body mass and normal body development, the maximum dose is determined by the
child’s age and weight. For example, in a child of 5 years weighing 50 lbs the dose of lidocaine HCl should not exceed 75 to 100 mg
(1.5 to 2 mg/lb). The use of even more dilute solutions (ie, 0.25 to 0.5%) and total dosages not to exceed 3 mg/kg (1.4 mg/lb) are
recommended for induction of intravenous regional anesthesia in children.
In order to guard against systemic toxicity, the lowest effective concentration and lowest effective dose should be used at all times. In
some cases it will be necessary to dilute available concentrations with 0.9% sodium chloride injection in order to obtain the required

Table 1 (Recommended Dosages) summarizes the recommended volumes and concentrations of Xylocaine Injection for various
types of anesthetic procedures. The dosages suggested in this table are for normal healthy adults and refer to the use of epinephrinefree
solutions. When larger volumes are required, only solutions containing epinephrine should be used except in those cases where
vasopressor drugs may be contraindicated.
There have been adverse event reports of chondrolysis in patients receiving intra-articular infusions of local anesthetics following
arthroscopic and other surgical procedures. Xylocaine is not approved for this use (see WARNINGS and DOSAGE AND
ADMINISTRATION).
These recommended doses serve only as a guide to the amount of anesthetic required for most routine procedures. The actual volumes
and concentrations to be used depend on a number of factors such as type and extent of surgical procedure, depth of anesthesia and
degree of muscular relaxation required, duration of anesthesia required, and the physical condition of the patient. In all cases the
lowest concentration and smallest dose that will produce the desired result should be given. Dosages should be reduced for children
and for the elderly and debilitated patients and patients with cardiac and/or liver disease.
The onset of anesthesia, the duration of anesthesia and the degree of muscular relaxation are proportional to the volume and
concentration (ie, total dose) of local anesthetic used. Thus, an increase in volume and concentration of Xylocaine Injection will
decrease the onset of anesthesia, prolong the duration of anesthesia, provide a greater degree of muscular relaxation and increase
the segmental spread of anesthesia. However, increasing the volume and concentration of Xylocaine Injection may result in a more
profound fall in blood pressure when used in epidural anesthesia. Although the incidence of side effects with lidocaine HCl is quite
low, caution should be exercised when employing large volumes and concentrations, since the incidence of side effects is directly
proportional to the total dose of local anesthetic agent injected.
For intravenous regional anesthesia, only the 50 mL single dose vial containing Xylocaine (lidocaine HCl) 0.5% Injection should be
used.
Epidural Anesthesia
For epidural anesthesia, only the following dosage forms Xylocaine Injection are recommended:
1% without epinephrine 10 mL Polyamp DuoFit™
1% without epinephrine 30 mL single dose solutions
1% with epinephrine 30 mL single dose solutions
1:200,000
1.5% without epinephrine 10 mL Polyamp DuoFit™
1.5% without epinephrine 20 mL Polyamp DuoFit™
1.5% with epinephrine 30 mL ampules, 30 mL single dose solutions
1:200,000
2% without epinephrine 10 mL Polyamp DuoFit™
2% with epinephrine 20 mL ampules, 20 mL single dose solutions
1:200,000
Although these solutions are intended specifically for epidural anesthesia, they may also be used for infiltration and peripheral nerve
block, provided they are employed as single dose units. These solutions contain no bacteriostatic agent.
In epidural anesthesia, the dosage varies with the number of dermatomes to be anesthetized (generally 2 to 3 mL of the indicated
concentration per dermatome).
Caudal and Lumbar Epidural Block
As a precaution against the adverse experience sometimes observed following unintentional penetration of the subarachnoid space,
a test dose such as 2 to 3 mL of 1.5% lidocaine HCl should be administered at least 5 minutes prior to injecting the total volume
required for a lumbar or caudal epidural block. The test dose should be repeated if the patient is moved in a manner that may have
displaced the catheter. Epinephrine, if contained in the test dose (10 to 15 mcg have been suggested), may serve as a warning of
unintentional intravascular injection. If injected into a blood vessel, this amount of epinephrine is likely to produce a transient“epinephrine response” within 45 seconds, consisting of an increase in heart rate and systolic blood pressure, circumoral pallor,
palpitations and nervousness in the unsedated patient. The sedated patient may exhibit only a pulse rate increase of 20 or more beats
per minute for 15 or more seconds. Patients on beta blockers may not manifest changes in heart rate, but blood pressure monitoring
can detect an evanescent rise in systolic blood pressure. Adequate time should be allowed for onset of anesthesia after administration
of each test dose. The rapid injection of a large volume of Xylocaine Injection through the catheter should be avoided, and, when
feasible, fractional doses should be administered.
In the event of the known injection of a large volume of local anesthetic solution into the subarachnoid space, after suitable
resuscitation and if the catheter is in place, consider attempting the recovery of drug by draining a moderate amount of cerebrospinal
fluid (such as 10 mL) through the epidural catheter.
MAXIMUM RECOMMENDED DOSAGES
Adults
For normal healthy adults, the individual maximum recommended dose of lidocaine HCl with epinephrine should not exceed 7 mg/kg
(3.5 mg/lb) of body weight, and in general it is recommended that the maximum total dose not exceed 500 mg. When used without
epinephrine the maximum individual dose should not exceed 4.5 mg/kg (2 mg/lb) of body weight, and in general it is recommended
that the maximum total dose does not exceed 300 mg. For continuous epidural or caudal anesthesia, the maximum recommended
dosage should not be administered at intervals of less than 90 minutes. When continuous lumbar or caudal epidural anesthesia is used
for non-obstetrical procedures, more drug may be administered if required to produce adequate anesthesia.
The maximum recommended dose per 90 minute period of lidocaine hydrochloride for paracervical block in obstetrical patients and
non-obstetrical patients is 200 mg total. One half of the total dose is usually administered to each side. Inject slowly, five minutes
between sides (see also discussion of paracervical block in PRECAUTIONS).
For intravenous regional anesthesia, the dose administered should not exceed 4 mg/kg in adults.
Children
It is difficult to recommend a maximum dose of any drug for children, since this varies as a function of age and weight. For children
over 3 years of age who have a normal lean body mass and normal body development, the maximum dose is determined by the
child’s age and weight. For example, in a child of 5 years weighing 50 lbs the dose of lidocaine HCl should not exceed 75 to 100 mg
(1.5 to 2 mg/lb). The use of even more dilute solutions (ie, 0.25 to 0.5%) and total dosages not to exceed 3 mg/kg (1.4 mg/lb) are
recommended for induction of intravenous regional anesthesia in children.
In order to guard against systemic toxicity, the lowest effective concentration and lowest effective dose should be used at all times. In
some cases it will be necessary to dilute available concentrations with 0.9% sodium chloride injection in order to obtain the required
final concentration.
NOTE: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever
the solution and container permit. The Injection is not to be used if its color is pinkish or darker than slightly yellow or if it contains a
precipitate.Table 1: Recommended Dosages

STERILIZATION, STORAGE AND TECHNICAL PROCEDURES
Disinfecting agents containing heavy metals, which cause release of respective ions (mercury, zinc, copper, etc) should not be used
for skin or mucous membrane disinfection as they have been related to incidents of swelling and edema. When chemical disinfection
of multi-dose vials is desired, either isopropyl alcohol (91%) or ethyl alcohol (70%) is recommended. Many commercially available
brands of rubbing alcohol, as well as solutions of ethyl alcohol not of USP grade, contain denaturants which are injurious to rubber
and therefore are not to be used.
Dosage forms listed as Xylocaine-MPF indicate single dose solutions that are Methyl Paraben Free (MPF).

AdultsSingle Direct Intravenous Injection (bolus)
The usual dose is 50 to 100 mg of lidocaine hydrochloride (0.7 to 1.4 mg/kg; 0.32 to 0.63 mg/lb) administered intravenously under ECG monitoring. This dose may be administered at the rate of approximately 25 to 50 mg/min (0.35 to 0.7 mg/kg/min; 0.16 to 0.32 mg/lb/min). Sufficient time should be allowed to enable a slow circulation to carry the drug to the site of action. If the initial injection of 50 to 100 mg does not produce a desired response, a second dose may be injected after 5 minutes. NO MORE THAN 200 TO 300 mg OF LIDOCAINE HYDROCHLORIDE SHOULD BE ADMINISTERED DURING A ONE HOUR PERIOD.
Continuous Intravenous Infusion
Following bolus administration, intravenous infusions of Xylocaine may be initiated at the rate of 1 to 4 mg/min of lidocaine hydrochloride (0.014 to 0.057 mg/kg/min; 0.006 to 0.026 mg/lb/min). The rate of intravenous infusions should be reassessed as soon as the patient’s basic cardiac rhythm appears to be stable or at the earliest signs of toxicity. It should rarely be necessary to continue intravenous infusions of lidocaine for prolonged periods.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever the solution and container permit. Do not use if solution is discolored or cloudy.
PediatricControlled clinical studies in the pediatric population to establish dosing schedules have not been conducted.
GeriatricIn general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
AdultsSingle Direct Intravenous Injection (bolus)
The usual dose is 50 to 100 mg of lidocaine hydrochloride (0.7 to 1.4 mg/kg; 0.32 to 0.63 mg/lb) administered intravenously under ECG monitoring. This dose may be administered at the rate of approximately 25 to 50 mg/min (0.35 to 0.7 mg/kg/min; 0.16 to 0.32 mg/lb/min). Sufficient time should be allowed to enable a slow circulation to carry the drug to the site of action. If the initial injection of 50 to 100 mg does not produce a desired response, a second dose may be injected after 5 minutes. NO MORE THAN 200 TO 300 mg OF LIDOCAINE HYDROCHLORIDE SHOULD BE ADMINISTERED DURING A ONE HOUR PERIOD.
Continuous Intravenous Infusion
Following bolus administration, intravenous infusions of Xylocaine may be initiated at the rate of 1 to 4 mg/min of lidocaine hydrochloride (0.014 to 0.057 mg/kg/min; 0.006 to 0.026 mg/lb/min). The rate of intravenous infusions should be reassessed as soon as the patient’s basic cardiac rhythm appears to be stable or at the earliest signs of toxicity. It should rarely be necessary to continue intravenous infusions of lidocaine for prolonged periods.

Table 1 (Recommended Dosages) summarizes the recommended volumes and concentrations of Xylocaine Injection for various types of anesthetic procedures. The dosages suggested in this table are for normal healthy adults and refer to the use of epinephrine-free solutions. When larger volumes are required, only solutions containing epinephrine should be used except in those cases where vasopressor drugs may be contraindicated.
There have been adverse event reports of chondrolysis in patients receiving intra-articular infusions of local anesthetics following arthroscopic and other surgical procedures. Xylocaine is not approved for this use (see WARNINGS and DOSAGE AND ADMINISTRATION).
These recommended doses serve only as a guide to the amount of anesthetic required for most routine procedures. The actual volumes and concentrations to be used depend on a number of factors such as type and extent of surgical procedure, depth of anesthesia and degree of muscular relaxation required, duration of anesthesia required, and the physical condition of the patient. In all cases the lowest concentration and smallest dose that will produce the desired result should be given. Dosages should be reduced for children and for the elderly and debilitated patients and patients with cardiac and/or liver disease.
The onset of anesthesia, the duration of anesthesia and the degree of muscular relaxation are proportional to the volume and concentration (ie, total dose) of local anesthetic used. Thus, an increase in volume and concentration of Xylocaine Injection will decrease the onset of anesthesia, prolong the duration of anesthesia, provide a greater degree of muscular relaxation and increase the segmental spread of anesthesia. However, increasing the volume and concentration of Xylocaine Injection may result in a more profound fall in blood pressure when used in epidural anesthesia. Although the incidence of side effects with lidocaine HCl is quite low, caution should be exercised when employing large volumes and concentrations, since the incidence of side effects is directly proportional to the total dose of local anesthetic agent injected.
For intravenous regional anesthesia, only the 50 mL single dose vial containing Xylocaine (lidocaine HCl) 0.5% Injection should be used.
Epidural Anesthesia
For epidural anesthesia, only the following dosage forms Xylocaine Injection are recommended:
1% without epinephrine 10 mL Polyamp DuoFit™
1% without epinephrine 30 mL single dose solutions
1% with epinephrine 30 mL single dose solutions
1:200,000
1.5% without epinephrine 10 mL Polyamp DuoFit™
1.5% without epinephrine 20 mL Polyamp DuoFit™
1.5% with epinephrine 30 mL ampules, 30 mL single dose solutions
1:200,000
2% without epinephrine 10 mL Polyamp DuoFit™
2% with epinephrine 20 mL ampules, 20 mL single dose solutions
1:200,000
Although these solutions are intended specifically for epidural anesthesia, they may also be used for infiltration and peripheral nerve block, provided they are employed as single dose units. These solutions contain no bacteriostatic agent.
In epidural anesthesia, the dosage varies with the number of dermatomes to be anesthetized (generally 2 to 3 mL of the indicated concentration per dermatome).
Caudal and Lumbar Epidural Block
As a precaution against the adverse experience sometimes observed following unintentional penetration of the subarachnoid space, a test dose such as 2 to 3 mL of 1.5% lidocaine HCl should be administered at least 5 minutes prior to injecting the total volume required for a lumbar or caudal epidural block. The test dose should be repeated if the patient is moved in a manner that may have displaced the catheter. Epinephrine, if contained in the test dose (10 to 15 mcg have been suggested), may serve as a warning of unintentional intravascular injection. If injected into a blood vessel, this amount of epinephrine is likely to produce a transient “epinephrine response” within 45 seconds, consisting of an increase in heart rate and systolic blood pressure, circumoral pallor, palpitations and nervousness in the unsedated patient. The sedated patient may exhibit only a pulse rate increase of 20 or more beats per minute for 15 or more seconds. Patients on beta blockers may not manifest changes in heart rate, but blood pressure monitoring can detect an evanescent rise in systolic blood pressure. Adequate time should be allowed for onset of anesthesia after administration of each test dose. The rapid injection of a large volume of Xylocaine Injection through the catheter should be avoided, and, when feasible, fractional doses should be administered.
In the event of the known injection of a large volume of local anesthetic solution into the subarachnoid space, after suitable resuscitation and if the catheter is in place, consider attempting the recovery of drug by draining a moderate amount of cerebrospinal fluid (such as 10 mL) through the epidural catheter.

When Xylocaine 2% Jelly is used concomitantly with other products containing lidocaine, the total dose contributed by all formulations must be kept in mind.
The dosage varies and depends upon the area to be anesthetized, vascularity of the tissues, individual tolerance, and the technique of anesthesia. The lowest dosage needed to provide effective anesthesia should be administered. Dosages should be reduced for children and for elderly and debilitated patients. Although the incidence of adverse effects with Xylocaine 2% Jelly is quite low, caution should be exercised, particularly when employing large amounts, since the incidence of adverse effects is directly proportional to the total dose of local anesthetic agent administered.
For Surface Anesthesia of the Male Adult UrethraWhen using Xylocaine 2% Jelly 30 mL tubes, sterilize the plastic cone for 5 minutes in boiling water, cool, and attach to the tube. The cone may be gas sterilized or cold sterilized, as preferred. Slowly instill approximately 15 mL (300 mg of lidocaine HCl) into the urethra or until the patient has a feeling of tension. A penile clamp is then applied for several minutes at the corona. An additional dose of not more than 15 mL (300 mg) can be instilled for adequate anesthesia.
Prior to sounding or cystoscopy, a penile clamp should be applied for 5 to 10 minutes to obtain adequate anesthesia. A total dose of 30 mL (600 mg) is usually required to fill and dilate the male urethra.
Prior to catheterization, smaller volumes of 5 to 10 mL (100 to 200 mg) are usually adequate for lubrication.
For Surface Anesthesia of the Female Adult UrethraWhen using Xylocaine 2% Jelly 30 mL tubes, sterilize the plastic cone for 5 minutes in boiling water, cool, and attach to the tube. The cone may be gas sterilized or cold sterilized, as preferred. Slowly instill 3 to 5 mL (60 to 100 mg of lidocaine HCl) of the jelly into the urethra. If desired, some jelly may be deposited on a cotton swab and introduced into the urethra. In order to obtain adequate anesthesia, several minutes should be allowed prior to performing urological procedures.
Lubrication for Endotracheal IntubationApply a moderate amount of jelly to the external surface of the endotracheal tube shortly before use. Care should be taken to avoid introducing the product into the lumen of the tube. Do not use the jelly to lubricate endotracheal stylettes. See WARNINGS and ADVERSE REACTIONS concerning rare reports of inner lumen occlusion. It is also recommended that use of endotracheal tubes with dried jelly on the external surface be avoided for lack of lubricating effect.

Adults
For normal healthy adults, the individual maximum recommended dose of lidocaine HCl with epinephrine should not exceed 7 mg/kg (3.5 mg/lb) of body weight, and in general it is recommended that the maximum total dose not exceed 500 mg. When used without epinephrine the maximum individual dose should not exceed 4.5 mg/kg (2 mg/lb) of body weight, and in general it is recommended that the maximum total dose does not exceed 300 mg. For continuous epidural or caudal anesthesia, the maximum recommended dosage should not be administered at intervals of less than 90 minutes. When continuous lumbar or caudal epidural anesthesia is used for non-obstetrical procedures, more drug may be administered if required to produce adequate anesthesia. The maximum recommended dose per 90 minute period of lidocaine hydrochloride for paracervical block in obstetrical patients and non-obstetrical patients is 200 mg total. One half of the total dose is usually administered to each side. Inject slowly, five minutes between sides (see also discussion of paracervical block in PRECAUTIONS). For intravenous regional anesthesia, the dose administered should not exceed 4 mg/kg in adults.
Children
It is difficult to recommend a maximum dose of any drug for children, since this varies as a function of age and weight. For children over 3 years of age who have a normal lean body mass and normal body development, the maximum dose is determined by the child’s age and weight. For example, in a child of 5 years weighing 50 lbs the dose of lidocaine HCl should not exceed 75 to 100 mg (1.5 to 2 mg/lb). The use of even more dilute solutions (ie, 0.25 to 0.5%) and total dosages not to exceed 3 mg/kg (1.4 mg/lb) are recommended for induction of intravenous regional anesthesia in children. In order to guard against systemic toxicity, the lowest effective concentration and lowest effective dose should be used at all times. In some cases it will be necessary to dilute available concentrations with 0.9% sodium chloride injection in order to obtain the required
final concentration.
NOTE: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever the solution and container permit. The Injection is not to be used if its color is pinkish or darker than slightly yellow or if it contains a precipitate.

THE ABOVE SUGGESTED CONCENTRATIONS AND VOLUMES SERVE ONLY AS A GUIDE. OTHER VOLUMES AND CONCENTRATIONS MAY BE USED PROVIDED THE TOTAL MAXIMUM RECOMMENDED DOSE IS NOT EXCEEDED. STERILIZATION, STORAGE AND TECHNICAL PROCEDURES
Disinfecting agents containing heavy metals, which cause release of respective ions (mercury, zinc, copper, etc) should not be used for skin or mucous membrane disinfection as they have been related to incidents of swelling and edema. When chemical disinfection of multi-dose vials is desired, either isopropyl alcohol (91%) or ethyl alcohol (70%) is recommended. Many commercially available brands of rubbing alcohol, as well as solutions of ethyl alcohol not of USP grade, contain denaturants which are injurious to rubber and therefore are not to be used.

The dosage of 2% Xylocaine DENTAL solutions (lidocaine HCl and epinephrine) depends on the physical status of the patient, the area of the oral cavity to be anesthetized, the vascularity of the oral tissues, and the technique of anesthesia used. The least volume of solution that results in effective local anesthesia should be administered; time should be allowed between injections to observe the patient for manifestations of an adverse reaction. For specific techniques and procedures of a local anesthesia in the oral cavity, refer to standard textbooks.
For most routine dental procedures, 2% Xylocaine DENTAL with epinephrine 1:100,000 (lidocaine HCl 2% with a 1:100,000 epinephrine concentration) is preferred. However, when greater depth and a more pronounced hemostasis are required, 2% Xylocaine DENTAL with epinephrine 1:50,000 (lidocaine HCl 2 % with 1:50,000 epinephrine concentration) should be used.
Dosage requirements should be determined on an individual basis. In oral infiltration and / or mandibular block, initial dosages of 1.0 - 5.0 mL (1/2 to 21⁄2 cartridges) of 2% Xylocaine DENTAL (lidocaine HCl 2% solutions with a 1:50,000 or a 1:100,000 epinephrine concentration) are usually effective.
In children under 10 years of age, it is rarely necessary to administer more than one-half cartridge (0.9-1.0 mL or 18-20 mg of lidocaine) per procedure to achieve local anesthesia for a procedure involving a single tooth. In maxillary infiltration, this amount will often suffice to the treatment of two or even three teeth. In the mandibular block, however, satisfactory anesthesia achieved with this amount of drug, will allow treatment of the teeth of an entire quadrant. Aspiration is recommended since it reduces the possibility of intravascular injection, thereby keeping the incidence of side effects and anesthetic failures to a minimum. Moreover, injection should always be made slowly.
Maximum recommended dosages for 2% Xylocaine DENTAL (lidocaine HCl 2% solutions with a 1:50,000 or a 1:100,000 epinephrine concentration).
AdultFor normal healthy adults, the amount of lidocaine HCl administered should be kept below 500 mg, and in any case, should not exceed 7 mg/kg (3.2 mg/lb) of body weight.
PediatricPediatric patients : It is difficult to recommend a maximum dose of any drug for pediatric patients since this varies as a function of age and weight. For pediatric patients of less than ten years who have a normal lean body mass and normal body development, the maximum dose may be determined by the application of one of the standard pediatric drug formulas (e.g., Clark's rule). For example, in pediatric patients of five years weighing 50 Ibs, the dose of lidocaine hydrochloride should not exceed 75-100mg when calculated according to Clark's rule. In any case, the maximum dose of lidocaine hydrochloride should not exceed 7 mg/kg (3.2 mg/lb) of body weight.
NOTE : Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever the solution and container permit. Solutions that are discolored and or contain particulate matter should not be used and any unused portion of a cartridge of 2% Xylocaine DENTAL should be discarded.
