What CAVERJECT is used for

What CAVERJECT does
CAVERJECT may be prescribed by your doctor for the treatment of erectile dysfunction (inability to maintain an erection to have sexual intercourse).
CAVERJECT may also be used to help in the diagnosis of erectile dysfunction.
CAVERJECT contains alprostadil. Alprostadil is also known as prostaglandin E1 (PGE1) and is found naturally in many parts of your body.

How CAVERJECT works

CAVERJECT works by increasing the blood flow to the penis. The increased blood flowing into the penis is trapped in the spongy erectile tissue of the penis called the corpora cavernosa. When these chambers fill with blood they swell and your penis becomes erect.
CAVERJECT is injected into a specific area of the penis and should produce an erection in 5 to 20 minutes. The erection should last for about 30 to 60 minutes.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed CAVERJECT for another reason.
This medicine is available only with a doctor's prescription.
