EHow Viagra 100mg treats sexual dysfunction
 
After entering the bloodstream, Viagra treats sexual dysfunction by inhibiting an enzyme called PDE5. This enzyme is responsible for regulating blood flow to the penis. Men with sexual dysfunction may have too much PDE5 in their systems, which can cause erection problems. Viagra corrects the imbalance by lowering PDE5 levels and increasing blood circulation. This allows men to have sufficient blood flow to the penis when sexually aroused. In most cases, men who take Viagra can get firm, long-lasting erections for sexual activity.

The side effects of Viagra
 
Viagra is generally well tolerated among men. However, minor side effects can include redness in the face, flushing, digestive upset, headaches, heartburn, faintness, dizziness, temporary vision changes, and blurred vision. These symptoms may last for several hours, but should go away on their own. Speak to your doctor if you experience bothersome side effects while taking Viagra. In rare cases, some patients experience severe side effects, including sudden vision loss, sudden hearing loss, and an erection that lasts more than 4 hours. If you experience these serious side effects, seek medical attention immediately.These statements have not been evaluated by the Food and Drug Administration.
