Viagra is sildenafil citrate, a known drug used to treat erectile dysfunction. It was made available by Pfizer in the market in 1998. Primarily, this drug markets to men of senior ages. But now, it has been made available even for middle-aged men.

Most men would like to have a good sex life but vices like drinking and smoking cause bad effects to their health. Truth is, even medical doctors would like to find out the real problem why some men experience problems in erection. Most men think that Viagra is the best solution for a common sex problem.

Of course, they would like to know the root cause of why some men don't have a happy sex life. But there is this kind of mentality in men that they don't like to consult a doctor for this reason because they are ashamed to talk about erection and penis problem. They are so embarrassed to talk about erectile dysfunction probably because it is an issue of masculinity. American and Asian men experience dysfunctions, as well as men in other countries. It's a worldwide problem in modern times. In 30 million men in America who are experiencing erectile dysfunctions, only 10% of them seek medical help and the rest just live with the problem.

Talking about sex problem in men and their erectile dysfunctions is a broad thing to talk about. There are lots of aspects to consider in treating this problem:

В• Lifestyle

В• Marital status

В• Environment

These are some aspects that need to be considered.

Viagra is a solution for men who want to have longer erections that could last them longer in bed with their partner. Viagra's main task is to increase the flow of blood in the arteries connected to the penis, the greater the amount of blood flow, the greater the erection will be.

The penis naturally lacks a certain enzyme that the penis needs in order to increase the blood flows to produce longer erections. If that enzyme is naturally present in the male penis, men won't need Viagra anymore.

But every drug has its side effects, and Viagra is not exempted. Fact is, every drug taken flows inside the body and absorbed by the veins. Consider antibiotics that when taken for a longer time can affect our liver and kidneys. Viagra, when taken for a longer time could exhibit side effects.

Most of the people who are taking Viagra say these are the common side effects they experience:

В• Retina is affected so that their perceptions of colors are affected. For this reason, men whose jobs include driving and operation of machineries are advised not to use this drug on a long-term.

В• Headache

В• Opening of the brain's arteries

В• Heart attack

These are some of the most common side effects of Viagra. Consult your doctor first before taking any type of medication or pill. Professional help would be your safest bet if you are uncertain about how your body will possibly react to the drugs.
