What is viagra and how it works?

Viagra is a medication which can be helpful in treating erectile dysfunction (commonly referred to as ED). Viagra was developed by mistake in 1985 by two scientists who were actually trying to develop a medication to aid in the treatment of high blood pressure and angina.

The two men failed in their quest as the drug exhibited no results as far as lowering blood pressure or decreasing the symptoms of angina. However the compound they created had one useful side effect. Men reported an elevated number of erections while taking the new drug. The scientist then decided to aim their attentions at perfecting their creation as a treatment for erectile dysfunction. Viagra was to begin trial in 1994 and was eventually licensed by the FDA in 1998.

For over ten years now Viagra and generic versions of the drug have been prescribed by doctors to help men of all ages achieve and maintain erections. Unlike some medications used in the treatment of ED, Viagra is generally safe for men have have other health issues such as high blood pressure, high cholesterol, heart disease, diabetes prostate problems, and depression .

It can most often be taken in combination with medications to treat these illnesses, with the exception of nitrates. Men who take nitrates should avoid taking Viagra. In the past some medications prescribed for erectile dysfunction were unsafe to take while on medication for high blood pressure. Viagra poses no such known issues. Of course any questions or concerns should be discussed with your physician before starting any new medication.

Viagra is taken orally as prescribed by a health care physician. It is normally taken once daily.
In some cases the drug may need to be taken 4 to 5 times before it begins to work, but it has been shown to help 4 out of 5 men with erectile dysfunction.

Many doctors will provide you with a free sample pack to try before you actually buy Viagra. The sample pack includes four free 50 mg pills of Viagra and a guide called getting the most from Viagra.
