Intracavernous injection
An intracavernous injection is an injection into the base of the penis. This injection site is often used to administer medications to check for or treat erectile dysfunction in adult men. The more common medications administered in this manner include Caverject, Trimix, Bimix, and Quadmix. These medications are all types of vasodilators and cause tumescence within 10-15 minutes.
Common side effects include priapism, bruising, fibrosis, Peyronies, and pain.
Priapism is also often treated with intracavernous injections, usually with sympathomimetic vasoconstricting drugs like adrenaline or phenylephrine.
