Viagra is used for:
Treating erectile dysfunction (ED). It may also be used for other conditions as determined by your doctor.
Viagra is a phosphodiesterase type 5 (PDE5) inhibitor. It works by helping to increase blood flow into the penis during sexual
stimulation. This helps you to achieve and maintain an erection.
Do NOT use Viagra if:
* you are allergic to any ingredient in Viagra
* you have been advised by your doctor to avoid sexual activity because of heart problems
* you are taking nitrates (eg, isosorbide, nitroglycerin) in any form (eg, tablet, capsule, patch, ointment), or nitroprusside
* you use certain recreational drugs called "poppers" (eg, amyl nitrate or nitrite, butyl nitrate or nitrite)
* you take another PDE5 inhibitor (eg, tadalafil, vardenafil) or another medicine that contains sildenafil
Contact your doctor or health care provider right away if any of these apply to you.

* if you are pregnant, planning to become pregnant, or are breast-feeding

* if you have allergies to medicines, foods, or other substances
* if you have a deformed penis (eg, cavernosal fibrosis, Peyronie disease), blood cell problems (eg, leukemia, multiple myeloma, sickle cell anemia), or any other condition that may increase the risk of a prolonged erection (priapism)
* if you have a history of a prolonged (more than 4 hours) or painful erection (priapism)
* if you have a history of certain eye problems (eg, macular degeneration, optic neuropathy, retinitis pigmentosa, sudden vision loss in one or both eyes) or hearing problems (eg, ringing in the ears, decreased hearing, hearing loss)

* Alpha-blockers (eg, doxazosin), medicines for high blood pressure, nitrates (eg, isosorbide, nitroglycerin), or nitroprusside because severe low blood pressure with dizziness, lightheadedness, and fainting may occur
* Azole antifungals (eg, itraconazole, ketoconazole), H2 antagonists (eg, cimetidine), HIV protease inhibitors (eg, ritonavir, saquinavir), macrolide antibiotics (eg, erythromycin), narcotic analgesics (eg, dihydrocodeine), or telithromycin because they may increase the risk of Viagra 's side effects
