About Erectile Dysfunction

If you have a problem getting or keeping an erection firm enough for sex, it's called erectile dysfunction (ED). This is a result of a lack of blood flow to the penis.

ED is more common than you think

About 30 million men in the United States have ED and ED affects men in different ways. Some men aren't able to get an erection at all. Others can get one, but it's not firm enough for sex. And some men get a firm erection but lose it before or during sex.

ED is a treatable medical condition. So for many men, treatment can help improve erections.

It is estimated that every year there will be over 600,000 new cases of ED in the US.


CAVERJECT is used to treat erectile dysfunction (ED) due to neurogenic, vasculogenic, psychogenic, or mixed etiology.

CAVERJECT should not be used in men hypersensitive to alprostadil, men with conditions that may predispose them to priapism (such as sickle cell anemia or trait, multiple myeloma or leukemia), men with anatomical deformities of the penis (such as angulation, cavernosal fibrosis or Peyronie’s disease), men with penile implants, or men for whom sexual activity is inadvisable or is contraindicated.
