Precautions

Drug information provided by: Micromedex

Do not use alprostadil if you have a penile implant unless advised by doctor.

If too much of this medicine is used, the erection lasts too long and does not reverse when it should. This condition is called priapism. If the erection is not reversed, the blood supply to the penis may be cut off and permanent damage may occur.

Contact your doctor immediately if the erection lasts longer than 4 hours or if it becomes painful. This may be a sign of priapism and must be treated right away to prevent permanent damage.

If you notice bleeding at the place where you injected the medicine, put pressure on the spot until the bleeding stops. If it doesn't stop within 5 minutes, check with your doctor. If you have an infection that is spread through blood, this could increase the risk of giving the infection to your sexual partner.

This medicine does not prevent pregnancy. Use birth control if you do not want pregnancy to occur.

This medicine will not protect you or your partner from sexually transmitted diseases.
