What is Caverject?

Caverject is a medicine used in the treatment of Erectile Dysfunction (impotence). It contains the active ingredient alprostadil. Alprostadil is the same as a naturally occurring chemical called prostaglandin E1. This prostaglandin widens the blood vessels and thins the blood. Caverject is used when the blood vessels and nerves in the penis no longer function properly. It increases blood flow, thereby increasing the amount of blood in the penis. Caverject is administered by injection directly into the penis. An erection usually occurs between 5 and 10 minutes after injection.

What is Caverject used for?

Caverject is used to treat Erectile Dysfunction (ED). ED is particularly common in older men, because the processes that enable the penis to become erect no longer function properly. Caverject offers an effective solution. It causes blood vessels in the corpus cavernosum to widen, allowing more blood to enter which ultimately causes the penis to become rigid and suitable for sexual intercourse. The advantage of Caverject is that it takes effect fast and that sexual stimulation is not necessarily required. An erection is produced simply by injecting the medicine.

How to use Caverject

The Caverject carton contains a powder and a fluid. Fill the syringe with the powder and the fluid to make the Caverject solution. Read through all of the instructions on the package leaflet so that you know exactly how to administer Caverject. Inject the solution into the corpus cavernosum. An erection will occur within 5 to 10 minutes and last between 30 and 60 minutes. Caverject should be used no more than three times per week, with at least 24 hours between each use. Make sure to follow the instructions on the package leaflet. Injections should be sterile and administered in the right place.


  • Do not inject into visible blood vessels.
  • Do not inject again if an erection fails to happen.
  • Cleanse the injection site with an alcohol swab prior to injection.
  • The side of the penis that is injected and the site of injection must be alternated.


Caverject is available in 10mcg/ml and 20mcg/ml doses. Your doctor will recommend the right dose for you. Never take a double dose.

Side effects

Caverject may cause side effects. The most common side effect of Caverject is mild to moderate pain during erection.

Other side effects include:

  • Bruising
  • Burning sensation
  • Tension in penis
  • Dizziness
Seek immediate medical assistance if an erection persists for three to six hours.

When not to use this medicine

Caverject should not be used in men who are allergic to alprostadil or with anatomical deformation of the penis, such as severe curvature, cavernosal fibrosis or Peyronie’s disease. Patients with a heart or lung disease are advised to take this medicine with caution. Caverject should not be used with other medicines for erectile dysfunction.

Driving ability/alcohol

Caverject may cause dizziness. Stay out of traffic if you experience this side effect. Alcohol impairs the ability to get an erection. It is therefore advisable to reduce your alcohol intake before taking this medicine.
