Viagra was the first erectile dysfunction medication discovered in 1989 and approved for treatment in the UK in 1998. It's an effective treatment, helping 74% of men who try it to get and keep erections hard enough for sex. Since Viagra was first patented by Pfizer, it has been referred to as the 'blue pill'.
By relaxing the muscle cells in the penis, Viagra increases blood flow to the penis which helps achieve an erection. Taking the little blue pill has been shown to be effective in achieving an erection for 75% of men with erectile dysfunction.
VIAGRA is a prescription medicine used to treat erectile dysfunction (ED). You will not get an erection just by taking this medicine. VIAGRA helps a man with erectile dysfunction get and keep an erection only when he is sexually excited (stimulated). VIAGRA is not for use in women or children.
What form(s) does this medication come in? Each blue, round, diamond-shaped tablet, marked "PFIZER" on one side and "VGR 25" on the other side, contains sildenafil citrate equivalent to 25 mg of sildenafil.
Pfizer patented sildenafil in 1996. Two years and many clinical trials later, in March of 1998, the new medication — now called Viagra — received approval from the Food and Drug Administration and went on sale as a prescription medication used to treat erectile dysfunction.
Generally, Viagra lasts around four hours. So it's important you don't take Viagra too long before you want to have sex, for example don't take Viagra in the morning if you expect to have sex at night. It's likely if you leave it that long, the effects of Viagra will have worn off.
Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained.

Viagra does not stimulate you sexually, it can only help you get an erection once you're already aroused. Because Viagra only helps you to get an erection by improving blood flow to the penis, it doesn't force you to get an erection, so it won't work unless you're sexually stimulated.
Viagra does not make your penis bigger. No pill does. It can help you get and maintain a firmer erection that lasts longer, though. To put it another way, sildenafil and other ED medications make the most of what you've got.
Nothing much would happen if someone without erectile dysfunction took Viagra, although they might think they feel better psychologically. But it would make a difference if you took it along with other drugs. Cocaine, marijuana, ecstasy, alcohol, nicotine, crystal meth - they all can cause erection problems.
A penile erection can normally last anywhere from a few minutes to about half an hour. On average, men have five erections a night while they're sleeping, each lasting about 25 to 35 minutes (Youn, 2017).
Because 100mg is the highest dose available, you should never 'double up' on tablets or take more than one in 24 hours. Sildenafil 100mg is the highest safe dosage you can take – if it is ineffective, you should try another ED treatment.
