What does Viagra do to a man :

VIAGRA works for men with erectile dysfunction (ED) by increasing blood flow to the penis so you can get and keep an erection hard enough for sex. Individual results may vary. It’s been proven to help guys with all degrees of ED. VIAGRA usually starts to work within 30-60 minutes.

How long does it take for viagra to work ;

Viagra normally starts working 30 to 60 minutes after you take it in oral tablet form. It may take up to 2 hours to work. Viagra doesn’t work on its own. You’ll still need to feel sexually aroused to get an erection.

Does Viagra stop you coming :

Sildenafil (Viagra) is used to treat erectile dysfunction (difficulty obtaining or maintaining erections). These drugs increase blood flow to the penis following sexual arousal, helping to produce an erection. They do not inhibit ejaculation, so they are not prescribed for premature ejaculation.

Can Viagra kill me :

According to a recent study of erection medication side effects during the decade from 1998 (the year Viagra was approved) through 2007, Viagra has been implicated in at least 1,824 deaths mostly from heart attacks. Cialis (approved in 2003) has been linked to 236 deaths, and Levitra (2003) to 121.

The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete sexual intercourse). Its use is now one of the standard treatments for erectile dysfunction, including for men with diabetes mellitus.

Antidepressant-associated sexual dysfunction :

Tentative evidence suggests that sildenafil may help men who experience antidepressant-induced erectile dysfunction.

High-altitude pulmonary edema :

Sildenafil has been studied for high-altitude pulmonary edema, but its use is currently not recommended for that indication.


Contraindications include:11

Sildenafil should not be used if sexual activity is inadvisable due to underlying cardiovascular risk factors.
