Treatment of Impotence
Talk to your doctor. Injections are available by prescription only. The most commonly used injection uses a drug called alprostadil (trade names include Caverject and Edex). Some doctors make their own proprietary mix of medications. Your doctor should give you clear instructions about how to use this type of treatment.
Some men find that combining injections with other types of treatment (for example, a vacuum pump) works better than either treatment alone.
