Papaverine (pa-PAV-er-een) 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, in the following dosage form:
Before Using This Medicine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For papaverine, the following should be considered:
Allergies- Tell your doctor if you have ever had any unusual or allergic reaction to papaverine. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Older adults- Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. Although there is no specific information comparing the use of papaverine for erectile dysfunction in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.
Other medicines- Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Other medical problems- The presence of other medical problems may affect the use of papaverine. Make sure you tell your doctor if you have any other medical problems, especially:

Precautions While Using This Medicine
Use papaverine injection exactly as directed by your doctor . Do not use more of it and do not use it more often than ordered. If too much is used, the erection may become so strong that it lasts too long and does not reverse when it should. This condition is called priapism, and it can be very dangerous. If the effect is not reversed, the blood supply to the penis may be cut off and permanent damage may occur.
Contact your doctor immediately if the erection lasts for longer than 4 hours or if it becomes painful . This may be a sign of priapism and must be treated right away to prevent permanent damage.
If you notice bleeding at the site when you inject papaverine, put pressure on the spot until the bleeding stops. If it doesn't stop, check with your doctor.
It is important for you to examine your penis regularly. Check with your doctor if you find a lump where the medicine has been injected or if you notice that your penis is becoming curved. These may be signs that unwanted tissue is growing (called fibrosis), which should be seen by your doctor.
