Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start using this medication and each time you get a refill. Learn all preparation and usage instructions. If you have any questions, ask your doctor or pharmacist.

This medication is given by injection into the penis as directed by your doctor. Before injecting each dose, clean the injection site with rubbing alcohol. It is important to change the location of the injection site with each dose to avoid problem areas under the skin. Therefore, choose an injection site on the other side of the penis from the site of the last dose, using a different area each time. After injection, apply pressure to the injection site with an alcohol swab for about 5 minutes to avoid bruising. Do not use a bent needle to inject this medication. If the needle is bent, replace it with a new needle. If the needle breaks during injection, contact your doctor right away.

Dosage is based on your medical condition and response to therapy. This medication should usually work within 5 to 20 minutes to produce an erection that lasts for about 1 hour. The manufacturer recommends that this medication be used no more than 3 times a week with at least 1 day between each dose.
