Viagra information

What is Viagra?
Viagra (sildenafil citrate) is a prescription medicine taken by mouth for the treatment of erectile dysfunction (ED) in men. ED is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. Viagra may help a man with ED get and keep an erection when he is sexually excited. Viagra is only for men, not for women and children, and must be used only under a doctor's care.

What does Viagra do?
As you've probably heard, Viagra (Sildenafil) is used to treat impotence in men who either can't have or can't maintain erections. On the market since March 1998, it's one of the most commercially successful drugs ever launched, with millions of prescriptions filled at a cost of more than $ 1 billion during the first year alone. It even has the blessing of the Vatican, on the ground that it can strengthen families.

Just as important, here's what Viagra can't do. It isn't an aphrodisiac; it can't get you aroused when you're not interested. And it's not a performance-enhancer. If you're healthy, Viagra won't give you a faster or harder erection or help you last longer. In fact, in healthy men it can even cause a painful, long-lasting erection (a condition called priapism) that may lead to impotence if it isn't treated quickly.

Know what to expect
- You will not get an instant erection. You must be aroused for viagra to work
- Viagra usually works in about 30 minutes
- Viagra works for 4 hours, so you can take your time
- After sex, your erection will go away
- To get the fastest results, take viagra on an empty stomach or after eating a low-fat meal

What happens if I miss a dose?
Viagra is used as needed, so you are not likely to miss a dose.

If you miss a dose of Revatio, take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.
