Caverject (Alprostadil)

Caverject package leaflet

Caverject is administered by injection into the penis. This is not painful or difficult to do if you follow the instructions provided with the injections. You should therefore read the package leaflet for Caverject carefully before you start taking this medicine. If you have any questions or concerns about taking this medicine, please do not hesitate to contact a doctor or pharmacy.

What is Caverject and what is it used for?

Caverject is a medicine to treat Erectile Dysfunction (ED or male impotence). It is not taken orally, but injected directly into the penis. The active ingredient alprostadil is injected into the corpus cavernosum with a superfine needle, which in turn improves blood flow to the penis. An erection usually occurs about five minutes after injection and lasts for 30 minutes to an hour.

  • If you have an erection for longer than four hours, contact a doctor immediately.
  • Are you currently taking other medicines? Be sure to tell your doctor. Caverject is known to interact with some types of medications.

How to use Caverject

Caverject is a powder medicine that comes with a sterile liquid for mixing. It is available in various strengths. Your doctor will determine the right dose for you depending on your specific needs. For instructions on how to mix the powder with the liquid and how to inject the solution into the side of the penis with the syringe that is provided in the kit, see the package leaflet. Caverject produces an erection in around five minutes. It should therefore be used right before you plan to have sex.
