How To Use
Read the Patient Information Leaflet provided by your pharmacist before you start using alprostadil and each time you get a refill. Learn all usage instructions in the product package. If any of the information is unclear, consult your doctor or pharmacist.
This medication is used by inserting the suppository into the penis as directed by your doctor. Dosage is based on your medical condition and response to therapy. This medication should usually work within 5-10 minutes to produce an erection that lasts for about 30-60 minutes. The manufacturer recommends that you use no more than 2 doses in a 24-hour period.
Inform your doctor if your condition persists or worsens (for example, the drug does not produce an erection or it becomes more difficult to get an erection).
Penis/testicle/groin pain, minor bleeding or spotting from the penis, dizziness, swelling (especially of leg veins), and rapid heartbeat may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if any of these unlikely but serious side effects occur:
In the very unlikely event you have a painful or prolonged erection lasting 4 or more hours, stop using this drug and seek immediate medical attention, or permanent problems could occur.
In female partners, vaginal burning/itching may occur. It is not clear if this side effect is caused by the medication or sexual intercourse itself. The use of a water-based lubricant may help prevent vaginal irritation.
