Questions & Answers
Side Effects & Adverse Reactions
SERIOUS AND OCCASIONALLY FATAL HYPERSENSITIVITY (ANAPHYLACTIC) REACTIONS HAVE BEEN REPORTED IN PATIENTS RECEIVING THERAPY WITH BETA-LACTAMS. THESE REACTIONS ARE MORE APT TO OCCUR IN PERSONS WITH A HISTORY OF SENSITIVITY TO MULTIPLE ALLERGENS.
THERE HAVE BEEN REPORTS OF PATIENTS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY WHO HAVE EXPERIENCED SEVERE HYPERSENSITIVITY REACTIONS WHEN TREATED WITH ANOTHER BETA-LACTAM. BEFORE INITIATING THERAPY WITH IMIPENEM AND CILASTATIN FOR INJECTION (I.V.), CAREFUL INQUIRY SHOULD BE MADE CONCERNING PREVIOUS HYPERSENSITIVITY REACTIONS TO PENICILLINS, CEPHALOSPORINS, OTHER BETA-LACTAMS, AND OTHER ALLERGENS. IF AN ALLERGIC REACTION OCCURS, IMIPENEM AND CILASTATIN FOR INJECTION SHOULD BE DISCONTINUED.
SERIOUS ANAPHYLACTIC REACTIONS REQUIRE IMMEDIATE EMERGENCY TREATMENT WITH EPINEPHRINE. OXYGEN, INTRAVENOUS STEROIDS, AND AIRWAY MANAGEMENT, INCLUDING INTUBATION, MAY ALSO BE ADMINISTERED AS INDICATED.
Seizures and other CNS adverse experiences, such as confusional states and myoclonic activity, have been reported during treatment with imipenem and cilastatin for injection (I.V.) (see PRECAUTIONS and ADVERSE REACTIONS).
Case reports in the literature have shown that co-administration of carbapenems, including imipenem, to patients receiving valproic acid or divalproex sodium results in a reduction in valproic acid concentrations. The valproic acid concentrations may drop below the therapeutic range as a result of this interaction, therefore increasing the risk of breakthrough seizures. Increasing the dose of valproic acid or divalproex sodium may not be sufficient to overcome this interaction. The concomitant use of imipenem and valproic acid/divalproex sodium is generally not recommended. Anti-bacterials other than carbapenems should be considered to treat infections in patients whose seizures are well controlled on valproic acid or divalproex sodium. If administration of imipenem and cilastatin for injection (I.V.) is necessary, supplemental anticonvulsant therapy should be considered (see PRECAUTIONS, Drug Interactions).
Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including imipenem and cilastatin for injection (I.V.), and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
C. difficile produces toxins A and B which contribute to the development of CDAD.
Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

Uses
Imipenem and cilastatin for injection (I.V.) is indicated for the treatment of serious infections caused by susceptible strains of the designated microorganisms in the conditions listed below:
- Lower respiratory tract infections. Staphylococcus aureus (penicillinase-producing strains), Acinetobacter species, Enterobacter species, Escherichia coli, Haemophilus influenzae, Haemophilus parainfluenzae1, Klebsiella species, Serratia marcescens
- Urinary tract infections (complicated and uncomplicated). Enterococcus faecalis, Staphylococcus aureus (penicillinase-producing strains) 1, Enterobacter species, Escherichia coli, Klebsiella species, Morganella morganii1, Proteus vulgaris1, Providencia rettgeri1, Pseudomonas aeruginosa
- Intra-abdominal infections. Enterococcus faecalis, Staphylococcus aureus (penicillinase-producing strains) 1, Staphylococcus epidermidis, Citrobacter species, Enterobacter species, Escherichia coli, Klebsiella species, Morganella morganii1, Proteus species, Pseudomonas aeruginosa, Bifidobacterium species, Clostridium species, Eubacterium species, Peptococcus species, Peptostreptococcus species, Propionibacterium species1, Bacteroides species including B. fragilis, Fusobacterium species
- Gynecologic infections. Enterococcus faecalis, Staphylococcus aureus (penicillinase-producing strains)1, Staphylococcus epidermidis, Streptococcus agalactiae (Group B streptococci), Enterobacter species1, Escherichia coli, Gardnerella vaginalis, Klebsiella species1, Proteus species, Bifidobacterium species1, Peptococcus species1, Peptostreptococcus species, Propionibacterium species1, Bacteroides species including B. fragilis1
- Bacterial septicemia. Enterococcus faecalis, Staphylococcus aureus (penicillinase-producing strains), Enterobacter species, Escherichia coli, Klebsiella species, Pseudomonas aeruginosa, Serratia species1, Bacteroides species including B. fragilis1
- Bone and joint infections. Enterococcus faecalis, Staphylococcus aureus (penicillinase-producing strains), Staphylococcus epidermidis, Enterobacter species, Pseudomonas aeruginosa
- Skin and skin structure infections. Enterococcus faecalis, Staphylococcus aureus (penicillinase-producing strains), Staphylococcus epidermidis, Acinetobacter species, Citrobacter species, Enterobacter species, Escherichia coli, Klebsiella species, Morganella morganii, Proteus vulgaris, Providencia rettgeri1, Pseudomonas aeruginosa, Serratia species, Peptococcus species, Peptostreptococcus species, Bacteroides species including B. fragilis, Fusobacterium species1
- Endocarditis. Staphylococcus aureus (penicillinase-producing strains)
- Polymicrobic infections. Imipenem and cilastatin for injection (I.V.) is indicated for polymicrobic infections including those in which S. pneumoniae (pneumonia, septicemia), S. pyogenes (skin and skin structure), or nonpenicillinase-producing S. aureus is one of the causative organisms. However, monobacterial infections due to these organisms are usually treated with narrower spectrum antibiotics, such as penicillin G.
Imipenem and cilastatin for injection (I.V.) is not indicated in patients with meningitis because safety and efficacy have not been established.
For Pediatric Use information, see PRECAUTIONS, Pediatric Use , and DOSAGE AND ADMINISTRATION sections.
Because of its broad spectrum of bactericidal activity against gram-positive and gram-negative aerobic and anaerobic bacteria, imipenem and cilastatin for injection (I.V.) is useful for the treatment of mixed infections and as presumptive therapy prior to the identification of the causative organisms.
Although clinical improvement has been observed in patients with cystic fibrosis, chronic pulmonary disease, and lower respiratory tract infections caused by Pseudomonas aeruginosa, bacterial eradication may not necessarily be achieved.
As with other beta-lactam antibiotics, some strains of Pseudomonas aeruginosa may develop resistance fairly rapidly during treatment with imipenem and cilastatin for injection (I.V.). During therapy of Pseudomonas aeruginosa infections, periodic susceptibility testing should be done when clinically appropriate.
Infections resistant to other antibiotics, for example, cephalosporins, penicillin, and aminoglycosides, have been shown to respond to treatment with imipenem and cilastatin for injection (I.V.).
To reduce the development of drug-resistant bacteria and maintain the effectiveness of imipenem and cilastatin for injection (I.V.) and other antibacterial drugs, imipenem and cilastatin for injection (I.V.) should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

2.1 General ConsiderationsThe side effects of irbesartan are generally rare and apparently independent of dose; those of hydrochlorothiazide are a mixture of dose-dependent (primarily hypokalemia) and dose-independent phenomena (e.g., pancreatitis), the former much more common than the latter [see Adverse Reactions (6)].
Maximum antihypertensive effects are attained within 2 to 4 weeks after a change in dose.
Irbesartan and hydrochlorothiazide tablets may be administered with or without food.
Irbesartan and hydrochlorothiazide tablets may be administered with other antihypertensive agents.
Renal impairment. The usual regimens of therapy with irbesartan and hydrochlorothiazide tablets may be followed as long as the patient’s creatinine clearance is > 30 mL/min. In patients with more severe renal impairment, loop diuretics are preferred to thiazides, so irbesartan and hydrochlorothiazide tablets are not recommended.
Hepatic impairment. No dosage adjustment is necessary in patients with hepatic impairment.
2.2 Add-On TherapyIn patients not controlled on monotherapy with irbesartan or hydrochlorothiazide, the recommended doses of irbesartan and hydrochlorothiazide tablets, in order of increasing mean effect, are (irbesartan-hydrochlorothiazide) 150/12.5 mg, 300/12.5 mg, and 300/25 mg. The largest incremental effect will likely be in the transition from monotherapy to 150/12.5 mg [see Clinical Studies (14.2)].
2.3 Replacement TherapyIrbesartan and hydrochlorothiazide tablets may be substituted for the titrated components.
2.4 Initial TherapyThe usual starting dose is irbesartan and hydrochlorothiazide tablets 150/12.5 mg once daily. The dosage can be increased after 1 to 2 weeks of therapy to a maximum of one 300/25 mg tablet once daily as needed to control blood pressure [see Clinical Studies (14.2)]. Irbesartan and hydrochlorothiazide tablets are not recommended as initial therapy in patients with intravascular volume depletion [see Warnings and Precautions (5.2)].

AdultsThe dosage recommendations for imipenem and cilastatin for injection (I.V.) represent the quantity of imipenem to be administered. An equivalent amount of cilastatin is also present in the solution. Each 125 mg, 250 mg, or 500 mg dose should be given by intravenous administration over 20 to 30 minutes. Each 750 mg or 1000 mg dose should be infused over 40 to 60 minutes. In patients who develop nausea during the infusion, the rate of infusion may be slowed.
The total daily dosage for imipenem and cilastatin for injection (I.V.) should be based on the type or severity of infection and given in equally divided doses based on consideration of degree of susceptibility of the pathogen(s), renal function, and body weight. Adult patients with impaired renal function, as judged by creatinine clearance ≤ 70 mL/min/1.73 m2, require adjustment of dosage as described in the succeeding section of these guidelines.
Intravenous Dosage Schedule for Adults with Normal Renal Function and Body Weight ≥ 70 kgDoses cited in Table 3 are based on a patient with normal renal function and a body weight of 70 kg. These doses should be used for a patient with a creatinine clearance of ≥ 71 mL/min/1.73 m2 and a body weight of ≥ 70 kg. A reduction in dose must be made for a patient with a creatinine clearance of ≤ 70 mL/min/1.73 m2 and/or a body weight less than 70 kg. (See Tables 4 and 5.)
Dosage regimens in column A of Table 3 are recommended for infections caused by fully susceptible organisms which represent the majority of pathogenic species. Dosage regimens in column B of Table 3 are recommended for infections caused by organisms with moderate susceptibility to imipenem, primarily some strains of P. aeruginosa.

There is no evidence that higher doses provide greater efficacy. However, patients over twelve years of age with cystic fibrosis and normal renal function have been treated with imipenem and cilastatin for injection (I.V.) at doses up to 90 mg/kg/day in divided doses, not exceeding 4 g/day.
Reduced Intravenous Schedule for Adults with Impaired Renal Function and/or Body Weight < 70 kgPatients with creatinine clearance of ≤ 70 mL/min/1.73 m2 and/or body weight less than 70 kg require dosage reduction of imipenem and cilastatin for injection (I.V.) as indicated in the tables below. Creatinine clearance may be calculated from serum creatinine concentration by the following equation:
To determine the dose for adults with impaired renal function and/or reduced body weight:
Choose a total daily dose from Table 3 based on infection characteristics. a) If the total daily dose is 1 g, 1.5 g, or 2 g, use the appropriate subsection of Table 4 and continue with step 3.
b) If the total daily dose is 3 g or 4 g, use the appropriate subsection of Table 5 and continue with step 3. From Table 4 or 5:
a) Select the body weight on the far left which is closest to the patient's body weight (kg).
b) Select the patient's creatinine clearance category.

There may be an increased risk of seizures when doses of 500 mg every 12 hours are administered to these patients.
Patients with creatinine clearance ≤ 5 mL/min/1.73 m2 should not receive imipenem and cilastatin for injection (I.V.) unless hemodialysis is instituted within 48 hours. There is inadequate information to recommend usage of imipenem and cilastatin for injection (I.V.) for patients undergoing peritoneal dialysis.
HemodialysisWhen treating patients with creatinine clearances of ≤ 5 mL/min/1.73 m2who are undergoing hemodialysis, use the dosage recommendations for patients with creatinine clearances of 6-20 mL/min/1.73 m2. (See Reduced Intravenous Dosage Schedule for Adults with Impaired Renal Function and/or Body Weight < 70 kg.) Both imipenem and cilastatin are cleared from the circulation during hemodialysis. The patient should receive imipenem and cilastatin for injection (I.V.) after hemodialysis and at 12 hour intervals timed from the end of that hemodialysis session.
Dialysis patients, especially those with background CNS disease, should be carefully monitored; for patients on hemodialysis, imipenem and cilastatin for injection (I.V.) is recommended only when the benefit outweighs the potential risk of seizures. (See PRECAUTIONS)
Pediatric PatientsSee PRECAUTIONS, Pediatric Patients.
For pediatric patients ≥ 3 months of age, the recommended dose for non-CNS infections is 15-25 mg/kg/dose administered every six hours. Based on studies in adults, the maximum daily dose for treatment of infections with fully susceptible organisms is 2 g per day, and of infections with moderately susceptible organisms (primarily some strains of P. aeruginosa) is 4 g/day. Higher doses (up to 90 mg/kg/day in older children) have been used in patients with cystic fibrosis.
For pediatric patients ≤ 3 months of age (weighing ≥ 1,500 g), the following dosage schedule is recommended for non-CNS infections:
< 1 wk of age: 25 mg/kg every 12 hrs 1-4 wks of age: 25 mg/kg every 8 hrs 4 wks-3 mos. of age: 25 mg/kg every 6 hrs.Doses less than or equal to 500 mg should be given by intravenous infusion over 15 to 30 minutes. Doses greater than 500 mg should be given by intravenous infusion over 40 to 60 minutes.
Imipenem and cilastatin for injection (I.V.) is not recommended in pediatric patients with CNS infections because of the risk of seizures.
Imipenem and cilastatin for injection (I.V.) is not recommended in pediatric patients < 30 kg with impaired renal function, as no data are available.

Patients with creatinine clearances of 6 to 20 mL/min/1.73 m2 should be treated with Imipenem and Cilastatin for Injection (I.V.) 125 mg or 250 mg every 12 hours for most pathogens. There may be an increased risk of seizures when doses of 500 mg every 12 hours are administered to these patients.
Patients with creatinine clearance ≤5 mL/min/1.73 m2 should not receive Imipenem and Cilastatin for Injection (I.V.) unless hemodialysis is instituted within 48 hours. There is inadequate information to recommend usage of Imipenem and Cilastatin for Injection (I.V.) for patients undergoing peritoneal dialysis.
Hemodialysis
When treating patients with creatinine clearances of ≤5 mL/min/1.73 m2 who are undergoing hemodialysis, use the dosage recommendations for patients with creatinine clearances of 6 to 20 mL/min/1.73 m2. (See Reduced Intravenous Dosage Schedule for Adults with Impaired Renal Function and/or Body Weight <70 kg.) Both imipenem and cilastatin are cleared from the circulation during hemodialysis. The patient should receive Imipenem and Cilastatin for Injection (I.V.) after hemodialysis and at 12 hour intervals timed from the end of that hemodialysis session. Dialysis patients, especially those with background CNS disease, should be carefully monitored; for patients on hemodialysis, Imipenem and Cilastatin for Injection (I.V.) is recommended only when the benefit outweighs the potential risk of seizures. (See PRECAUTIONS.)Pediatric Patients
See PRECAUTIONS, Pediatric Patients.For pediatric patients ≥3 months of age, the recommended dose for non-CNS infections is 15 to 25 mg/kg/dose administered every six hours. Based on studies in adults, the maximum daily dose for treatment of infections with fully susceptible organisms is 2 g per day, and of infections with moderately susceptible organisms (primarily some strains of P. aeruginosa) is 4 g/day. Higher doses (up to 90 mg/kg/day in older children) have been used in patients with cystic fibrosis.
For pediatric patients ≤3 months of age (weighing ≥1,500 g), the following dosage schedule is recommended for non-CNS infections:
<1 wk of age: 25 mg/kg every 12 hrs
1 to 4 wks of age: 25 mg/kg every 8 hrs
4 wks to 3 mos. of age: 25 mg/kg every 6 hrs.Doses less than or equal to 500 mg should be given by intravenous infusion over 15 to 30 minutes. Doses greater than 500 mg should be given by intravenous infusion over 40 to 60 minutes.
Imipenem and Cilastatin for Injection (I.V.) is not recommended in pediatric patients with CNS infections because of the risk of seizures.
Imipenem and Cilastatin for Injection (I.V.) is not recommended in pediatric patients <30 kg with impaired renal function, as no data are available.

2.1 Recommended DosingThe recommended dose of JANUVIA is 100 mg once daily. JANUVIA can be taken with or without food.
2.2 Patients with Renal InsufficiencyFor patients with mild renal insufficiency (creatinine clearance [CrCl] greater than or equal to 50 mL/min, approximately corresponding to serum creatinine levels of less than or equal to 1.7 mg/dL in men and less than or equal to 1.5 mg/dL in women), no dosage adjustment for JANUVIA is required.
For patients with moderate renal insufficiency (CrCl greater than or equal to 30 to less than 50 mL/min, approximately corresponding to serum creatinine levels of greater than 1.7 to less than or equal to 3.0 mg/dL in men and greater than 1.5 to less than or equal to 2.5 mg/dL in women), the dose of JANUVIA is 50 mg once daily.
For patients with severe renal insufficiency (CrCl less than 30 mL/min, approximately corresponding to serum creatinine levels of greater than 3.0 mg/dL in men and greater than 2.5 mg/dL in women) or with end-stage renal disease (ESRD) requiring hemodialysis or peritoneal dialysis, the dose of JANUVIA is 25 mg once daily. JANUVIA may be administered without regard to the timing of dialysis.
Because there is a need for dosage adjustment based upon renal function, assessment of renal function is recommended prior to initiation of JANUVIA and periodically thereafter. Creatinine clearance can be estimated from serum creatinine using the Cockcroft-Gault formula. [See Clinical Pharmacology (12.3).] There have been postmarketing reports of worsening renal function in patients with renal insufficiency, some of whom were prescribed inappropriate doses of sitagliptin.
2.3 Concomitant Use with an Insulin Secretagogue (e.g., Sulfonylurea) or with InsulinWhen JANUVIA is used in combination with an insulin secretagogue (e.g., sulfonylurea) or with insulin, a lower dose of the insulin secretagogue or insulin may be required to reduce the risk of hypoglycemia. [See Warnings and Precautions (5.3).]
