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.

Physostigmine affects chemicals in the body that control the signals sent from the nervous system to the muscles to activate muscle movement.

Physostigmine is used to reverse the effects of certain drugs or substances that interfere with this nerve-muscle communication. Such substances include atropine, scopolamine, belladonna, antihistamines, some antidepressants, and other anticholinergic (AN tye KOE lin ER jik) drugs.

Physostigmine may also be used for purposes not listed in this medication guide.
