Generic Name: alprostadil (al-PROS-ta-dil)
Brand Name: Examples include Caverject and Caverject Impulse
Caverject Impulse is used for:
Treating erectile problems in men. It may also be used to help diagnose erectile dysfunction.
Caverject Impulse is a prostaglandin (PGE-1). It works by relaxing certain muscles in the penis and widening blood vessels, which increases blood flow to the penis and helps to cause an erection. When the effect of the alprostadil wears off, blood flow returns to normal and the erection disappears.

- you are allergic to any ingredient in Caverject Impulse
- you have blood problems (eg, sickle cell anemia or sickle cell trait, leukemia), bone marrow problems (eg, multiple myeloma), or other conditions that may increase your risk for a prolonged, painful erection (priapism)
- you have a penile implant, deformed penis, or certain other penile problems (eg, Peyronie disease, fibrosis of the penis)
- you have any other physical reason that you should not have sexual intercourse
Contact your doctor or health care provider right away if any of these apply to you.
