Viagra is an FDA-approved medication used to treat male impotence. In fact, when it was introduced in 1998, it was the first treatment for male impotence on the market. It remains popular today because clinical studies have shown that it works well for men with male impotence, regardless of age. Viagra is a fast-acting medication that can last for up to 4 hours.

Male impotence can be caused by a variety of factors. A common reason, particularly among older men, is male impotence caused by reduced blood flow to the penis. As a PDE5 inhibitor, Viagra relaxes the muscles in the penis, allowing the vessels to dilate and fill with blood. The result is improved blood flow that facilitates an erection once you become sexually aroused. Viagra has been shown to work well for most men, regardless of age, even if you have had male impotence for several years.

In clinical trials, Viagra has been shown to be effective for up to 80% of men. As the first FDA-approved treatment for male impotence, its safety and effectiveness have been well documented over the years. Since it is a proven treatment for male impotence, most health insurance plans will cover Viagra, which makes the medication more affordable.

As an oral medication, it’s simple and convenient to use. You should take Viagra approximately 30 to 60 minutes before sexual activity. The effects can last for up to 4 hours. Some men even find that they can get more than one erection per dose.

Take Viagra as instructed by the prescribing physician. Typically, Viagra works best if taken approximately 1 hour before a sexual encounter. To get an erection, you will need to be sexually aroused.

Viagra can be taken in 25 mg, 50 mg, and 100 mg doses. The typical starting dose is 50 mg, but your doctor can help you determine the best starting dose for you. Some patients must increase their dose to 100 mg to get the desired effect. For others, a lower dose is sufficient. Do not take Viagra with a meal high in fat, as it may reduce the effectiveness.

Do not take more than one dose of Viagra in a 24-hour period, and never take Viagra with other medications used to treat male impotence. Viagra does not protect against pregnancy or sexually transmitted diseases.
