Viagra has exploded the market from the very first day when it came into existence some four years ago. The whole media and medicine world flocked to study the post launch effect and repercussions of the drug. Viagra dominated the talks and discussion around the world. In fact, the word Viagra became the buzzword in "medicine cabinet".

Time passed and the drug started gaining the confidence and acceptance of people suffering from Erectile Dysfunction. An authentic data shows that nearly 30 million men in US suffer from impotence. For a person suffering from the discrepancy, his self-esteem, sexual life and metal health are affected to a large extent citing the relationship with his partner that is the worst hit in the whole process.

The causes of Impotence may be psychological, mental or a physiological one but in most of the cases, the prime reason has been the biological problems. Impotence, as we all know affects people who are aging, though there have been cases where young people have suffered, but that is limited in number. People of old age suffer from different problems such as diabetes, kidney problems, and cardiovascular disorders. These problems make a gateway for a serious problem that is Impotence.

The success of Viagra today speaks the sustainability of the drug as it has successfully treated people suffering from Erectile Dysfunction irrespective of the nature of the cause.

However, there are certain facts that put a "question mark" on the very sustainability factor. There have been cases where Viagra has been found to carry some side effects, whether it is the problem associated with blindness or mental health.

The duplicate and generic version of Viagra has been in the market for some time now and the number of people using the generic version has increased. There have been cases where fake Viagra has been discovered from the vendors. Pfizer is the only manufacturer of Viagra, so it is advisable to refrain from using any drug made by a "second brand".
