How it Works

Alprostadil comes as a shot to inject into the penis. You must be trained by your doctor before using alprostadil at home. Use alprostadil before sex. It produces an erect penis within 5-20 minutes of injection (into the side of the upper third of the penis, as directed by your doctor). Generally, alprostadil should not be used more than three times a week or more than once every 24 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use alprostadil exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Your doctor will administer the first dose in his or her office to determine the appropriate dose you should receive.
