  The dose of CAVERJECT should be individualized for each patient by careful titration under supervision by the physician. In clinical studies, patients were treated with CAVERJECT Sterile Powder in doses ranging from 0.2 to 140 mcg; however, since 99% of patients received doses of 60 mcg or less, doses of greater than 60 mcg are not recommended. In general, the lowest possible effective dose should always be employed. In clinical studies, over 80% of patients experienced an erection sufficient for sexual intercourse after intracavernosal injection of CAVERJECT.

  Initial Titration in Physician's Office Erectile Dysfunction of Vasculogenic, Psychogenic, or Mixed Etiology

  Dosage titration should be initiated at 2.5 mcg of alprostadil. The 10 mcg strength of CAVERJECT IMPULSE is designed to allow delivery of a 2.5 mcg dose of alprostadil (see General Procedure for Solution Preparation). If there is a partial response at 2.5 mcg, the dose may be increased by 2.5 mcg to a dose of 5 mcg within 1 hour. No more than 2 doses during initial titration should be given within a 24-hour period. If additional titration is required, doses in increments of 5 to 10 mcg may be given at least 24 hours apart until the dose that produces an erection suitable for intercourse and not exceeding a duration of 1 hour is reached. If there is no response to the initial 2.5-mcg dose, the second dose may be increased to 7.5 mcg within 1 hour. No more than 2 doses during initial titration should be given within a 24-hour period. If additional titration is required, doses in increments of 5 to 10 mcg may be given at least 24 hours apart. The patient must stay in the physician's office until complete detumescence occurs.

  Erectile Dysfunction of Pure Neurogenic Etiology (Spinal Cord Injury)

  Dosage titration should be initiated at 1.25 mcg of alprostadil. Because CAVERJECT IMPULSE is designed to deliver doses of 2.5 mcg or greater (see General Procedure for Solution Preparation), CAVERJECT Sterile Powder may be used for an initial dose of 1.25 mcg. The initial dose may be increased by 1.25 mcg to a dose of 2.5 mcg within 1 hour. No more than 2 doses during initial titration should be given within a 24-hour period. If additional titration is required, a dose of 5 mcg may be given during the next 24 hours. Thereafter, doses in increments of 5 mcg may be given at least 24 hours apart until the dose that produces an erection suitable for intercourse and not exceeding a duration of 1 hour is reached. The patient must stay in the physician's office until complete detumescence occurs.

  The majority of patients (56%) in one clinical study involving 579 patients with erectile dysfunction of various etiologies were titrated to doses of greater than 5 mcg but less than or equal to 20 mcg. The mean dose at the end of the titration phase was 17.8 mcg of alprostadil.

  Maintenance Therapy

  The first injections of CAVERJECT must be done at the physician's office by medically trained personnel. Self-injection therapy by the patient should be started only after the patient is properly instructed and well trained in the self-injection technique. The physician should make a careful assessment of the patient's skills and competence with this procedure. The intracavernosal injection must be done under sterile conditions. The site of injection is usually along the dorso-lateral aspect of the proximal third of the penis. Visible veins should be avoided. The side of the penis that is injected and the site of injection must be alternated; the injection site must be cleansed with an alcohol swab.

  The dose of CAVERJECT that is selected for self-injection treatment should provide the patient with an erection that is satisfactory for sexual intercourse and that is maintained for no longer than 1 hour. If the duration of erection is longer than 1 hour, the dose of CAVERJECT should be reduced. Self-injection therapy for use at home should be initiated at the dose that was determined in the physician's office; however, dose adjustment, if required (up to 57% of patients in one clinical study), should be made only after consultation with the physician. The dose should be adjusted in accordance with the titration guidelines described above. The effectiveness of CAVERJECT for long-term use of up to 6 months has been documented in an uncontrolled, self-injection study. The mean dose of CAVERJECT Sterile Powder at the end of 6 months was 20.7 mcg in this study. CAVERJECT IMPULSE in the 10 mcg strength is designed to deliver a minimum dose of 2.5 mcg and a maximum dose of 10 mcg. CAVERJECT IMPULSE in the 20 mcg strength is designed to deliver a minimum dose of 5 mcg and a maximum dose of 20 mcg. The physician should determine the most suitable formulation of CAVERJECT for the individual patient (CAVERJECT IMPULSE or CAVERJECT Sterile Powder).

  Careful and continuous follow-up of the patient while in the self-injection program must be exercised. This is especially true for the initial self-injections, since adjustments in the dose of CAVERJECT may be needed. The recommended frequency of injection is no more than 3 times weekly, with at least 24 hours between each dose. All formulations of CAVERJECT are intended for single use only and should be discarded after use. The user should be instructed in the proper disposal of the injection materials (e.g., delivery system, needles).

  While on self-injection treatment, it is recommended that the patient visit the prescribing physician's office every 3 months. At that time, the efficacy and safety of the therapy should be assessed, and the dose of CAVERJECT should be adjusted, if needed.

  CAVERJECT as an Adjunct to the Diagnosis of Erectile Dysfunction

  In the simplest diagnostic test for erectile dysfunction (pharmacologic testing), patients are monitored for the occurrence of an erection after an intracavernosal injection of CAVERJECT. Extensions of this testing are the use of CAVERJECT as an adjunct to laboratory investigations, such as duplex or Doppler imaging, 133Xenon washout tests, radioisotope penogram, and penile arteriography, to allow visualization and assessment of penile vasculature. For any of these tests, a single dose of CAVERJECT that induces an erection with firm rigidity should be used.

  General Procedure for Solution Preparation

  CAVERJECT IMPULSE consists of a disposable, single-dose, dual chamber syringe system. The system includes a glass cartridge, which contains sterile, freeze-dried alprostadil in the front chamber and sterile bacteriostatic water for injection in the rear chamber. Following proper reconstitution instructions, the 10 mcg strength syringe can deliver up to 0.5 mL of solution. Each 0.5 mL of solution contains 10 mcg of alprostadil, 324.7 mcg of alpha cyclodextrin, 45.4 mg of lactose, 23.5 mcg of sodium citrate, and 4.45 mg of benzyl alcohol. The delivery system can be set to deliver a solution volume of 0.125, 0.25, 0.375, or 0.50 mL to enable administration of 2.5, 5, 7.5, or 10 mcg of alprostadil. Following proper reconstitution instructions, the 20 mcg strength syringe can deliver up to 0.5 mL of solution. Each 0.5 mL of solution contains 20 mcg of alprostadil, 649.3 mcg of alpha cyclodextrin, 45.4 mg of lactose, 23.5 mcg of sodium citrate, and 4.45 mg of benzyl alcohol. The delivery system can be set to deliver a solution volume of 0.125, 0.25, 0.375, or 0.50 mL to enable administration of 5, 10, 15, or 20 mcg of alprostadil. After reconstitution, the solution of CAVERJECT should be used within 24 hours when stored at or below 25°C (77°F). Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever the solution and container permit. The product should not be used if particulate matter or discoloration are present. Following a single use, the injection delivery system and any remaining solution should be properly discarded.

  Caution

  CAVERJECT IMPULSE is for single use only. Do not use any remaining CAVERJECT solution.
