Description
What is Viagra?
Viagra (sildenafil) relaxes muscles and increases blood flow to particular areas of the body.
Viagra is used to treat erectile dysfunction (impotence) in men. Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. Buy Sildenafil Online from 50p per tablet

Important information
You should not use Viagra if you are allergic to sildenafil.
Do not take Viagra if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”). Taking Viagra with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.
Stop using this medicine and get emergency medical help if you have sudden vision loss.
Before taking this medicine
You should not use Viagra if you are allergic to sildenafil.
Do not take Viagra if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”). Taking Viagra with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
To make sure Viagra is safe for you, tell your doctor about your other medical conditions, especially:
heart disease or heart rhythm problems, coronary artery disease;
a recent history (in the past 6 months) of a heart attack, stroke, or congestive heart failure;
high or low blood pressure;
liver or kidney disease;
a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
a bleeding disorder such as hemophilia;
a stomach ulcer;
retinitis pigmentosa (an inherited condition of the eye);
a physical deformity of the penis (such as Peyronie’s disease); or
if you have been told you should not have sexual intercourse for health reasons.
Viagra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Viagra, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old. It is not clear whether Viagra is the actual cause of vision loss. Stop using Viagra and get emergency medical help if you have sudden vision loss.
