Precautions

Drug information provided by: Merative, Micromedex®

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

Use a condom when having sexual intercourse with a pregnant female while using this medicine. Although harm to the fetus is unlikely, using a condom will protect the fetus from exposure to this medicine. If a woman can become pregnant, use of contraceptive methods is recommended because the effects of this medicine on early pregnancy are not known.

This medicine may make you dizzy or lightheaded. Do not drive or do anything that could be dangerous until you know how this medicine affects you.

If too much 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.

This medicine will not prevent pregnancy or protect you or your partner from diseases such as syphilis, herpes, or HIV. Use a latex condom during sex for protection.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
