Phentolamine given by injection causes blood vessels to expand, thereby increasing blood flow. When injected into the penis (intracavernosal), it increases blood flow to the penis, which results in an erection.
This medicine 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.
Phentolamine may also be used to reverse the effects of an anesthetic medicine in soft tissues, such as the lips and tongue. It may be used to help quickly restore normal sensation and function in patients who have received local dental anesthesia .
Phentolamine is available only with your doctor's prescription.
