Sildenafil (Viagra) is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Revatio) is used to improve the ability to exercise in adults with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Children should not usually take sildenafil, but in some cases, a doctor may decide that sildenafil (Revatio) is the best medication to treat a child's condition. Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily. If you are taking sildenafil to treat erectile dysfunction, you should know that it does not cure erectile dysfunction or increase sexual desire. Sildenafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).

You may want to avoid taking it with a high-fat meal, because that will delay the effects of the medicine. It's also a good idea not to take Viagra with grapefruit juice, for two reasons. Like high-fat food, grapefruit juice can delay the action of Viagra. In addition, it can increase your blood levels of the medication, which might cause toxic side effects. I know my best reaction to Viagra is on an empty stomach. However, if I am having sex about an hour after a meal, should I take the pill before the meal (i.e., about two-three hours before having sex) or after the meal? Someone once ask me what he was supposed to do while he waited for the viagra to work, I told him one word, foreplay. If you're all ready as soon as you're done eating, I can guarantee you she isn't. I wouldn't suggest you take it before the meal, then eat. The time it takes you if you take it half an hour after you eat, gives you time to be a little romantic. So if home having dinner a date I should wait about a half hour after eating to pop the pill? Then while waiting for it to take effect I could be doing foreplay? My stomach still could be kind of full after half an hour. Sometimes I will add a extra 10 mg to the 50 mg I normally take.
