A drug is injected directly into the shaft of the penis prior to a man having sexual intercourse. Although it sounds a bit worrying it is easy to learn.

The medication usually works within about 15 minutes. Even though many men may be uncomfortable injecting themselves, expert believe injections are perhaps the fastest method for men with E.D. to achieve an erection.

The most popular E.D. injection used today is called “Caverject”. This method involves a small-needle injected into the corpus cavernosum in the penis and by relaxing smooth muscle tissue it in turn enhances the blood flow to the penis, creating an erection. Typically doctors prescribe the injection for men with E.D. that is neurological, vascular, and psychological or of mixed origin.

Men treated with Caverject receive initial injections from medically-trained personnel to determine optimum dosing from 5 mg to 20 mg. Up to 60 mg can be injected at one time and Caverject can be administered by the patient himself once he has been trained to self-inject. The syringes are self-contained, easy to use and also come with a kit that contains the alcohol wipes used before and after to clean the penis.

It should be noted that Caverject may cause mild pain, irritation or slight bleeding at the injection site and also a possibility of tenderness or swelling of the penis as well as redness, lumps, or an unusual curving of the penis.
