How should I use alprostadil?
A healthcare provider will give your first dose and teach you how to properly use the medication by yourself.
Follow all directions on your prescription label and read all medication guides. Use the medicine exactly as directed.
Alprostadil is used only when needed. An erection should occur within 5 to 20 minutes and last up to 60 minutes.
Alprostadil injection is injected into the side of the penis.
Alprostatil transurethral pellet is a very small suppository to be inserted into the opening of the penis (the urethra).
Do not use more than 2 pellets in one day. Do not use more than 3 injections per week. Wait at least 24 hours between each injection.
Ask your doctor or pharmacist if you don't understand how to use the injection.
Prepare an injection only when you are ready to give it. Call your pharmacist if the medicine looks cloudy, has changed colors, or has particles in it.
Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.
Call your doctor if a needle breaks while you are injecting alprostadil. If you can grasp the broken end, remove the needle right away.
Your doctor should check you every 3 months to be sure alprostadil is not causing harmful effects on your penis.
