Male impotence or erectile dysfunction (ED) if speaking in medical terms, can affect men regardless of their age. Not so long ago there were only a few treatments for impotence and successful cases were very rare. That was before the creation of the best known ED drug, which everyone has definitely heard of. That was before “the little blue pill” we know as Viagra.

Viagra (sildenafil) makes part of a group of drugs that restrict the enzymes called phosphodiesterase from working too quickly. By controlling phosphodiesterase, sildenafil aids in maintaining an erection, which occurs when there is physical stimulation of the penis. There are numerous stories about the effectiveness of Viagra. And this is mostly true, with men all over the world and of all ages enjoying a new found sexual youth thanks to the little blue pill. But like any other prescription drug, Viagra has its pitfalls and issues when used. So we’d better take a better look at Viagra.

How is Viagra prescribed?

Viagra comes in the form of oral pill in dosages of 25mg, 50mg and 100mg.

Men up to 65 years old - Viagra 50mg is prescribed to be consumed once daily, 30 minutes to 4 hours prior sexual intercourse. In case when 50mg isn’t effective, your physician may prescribe 100mg to be taken once a day 30 minutes to 4 hours before sex.

Men older than 65 years - Viagra 25mg is prescribed to be consumed 30 minutes to 4 hours prior sex. In some cases, men older then 65 can be prescribed with higher doses.

CAUTION — Do not increase the dosage of Viagra on your own without consulting with your doctor first!

Viagra has become so popular that everyone wants to take it. In fact, in some circles Viagra is becoming a party drug. But there are certain groups of people who won’t experience any effects when using Viagra or should even avoid taking it:

Women. Viagra is not recommended and approved to be used by women. Therefore, women should avoid taking Viagra.

Older Men. Men older than 65 have an increased sensitivity to the effects of Viagra. Because of this men older than 65 have to take a smaller dose, which will be increased gradually if tolerated well.
