Papaverine (Injection Route)Drug Information provided by: Micromedex
Papaverine belongs to the group of medicines called vasodilators. Vasodilators cause blood vessels to expand, thereby increasing blood flow. Papaverine is used to produce erections in some men with erectile dysfunction. When papaverine is injected into the penis (intracavernosal), it increases blood flow to the penis, which results in an erection.
Papaverine injection should not be used as a sexual aid by men who do not have erectile dysfunction. If the medicine is not used properly, permanent damage to the penis and loss of the ability to have erections could result.
Papaverine is available only with your doctor's prescription.
