What Is The Use Of Caverject?

It is not recommended for use in children under 18 years of age.

How Does A Caverject Work?

Caverject (Alprostadil for injection) belongs to a class of drugs known as prostaglandins. It helps to relax the smooth muscles of the penis. This allows more blood to flow into the penis and thus helps to achieve and/or maintain an erection.

How Is Caverject Supplied and Stored?

Caverject is manufactured by Pfizer Canada Inc. and is supplied in boxes that contain five cases. Each case consists of the following:
  • One vial of Caverject sterile powder with the strength of 20 mcg.
  • One prefilled syringe containing bacteriostatic water. This is sterile water contains a preservative and is used to dissolve Caverject. This solution does not contain the active ingredient. You will need to use this syringe after attaching the needle, to inject the medication into your penis.
  • One 27-gauge, 0.5 inch needle. Keep the plastic cover on the needle until ready to inject.
  • Two alcohol swabs. It is important to use the swabs to maintain hygienic conditions and prevent infection.
The unused vials of Caverject 20 mcg sterile powder should be stored at a temperature between 2°C and 30°C, protected from freezing. Once dissolved, the Caverject solution should be used immediately.
