Viagra
Viagra is a medicine used commonly these days for treating failure of having or maintaining an erection in men. This condition is generally called impotence. In medical terms it is known as erectile dysfunction (ED). Since the FDA approved it in March 1998, over sixteen million men around the world have used it to improve their sex life. |

Chemical Nature of Viagra
The potent chemical in Viagra is sildenafil citrate, developed originally in 1991 to treat angina or chest pain. Recently, a new drug Tadalafil has been developed to treat men with ED problems who do not respond to sildenafil.
Buy Viagra on Prescription
While some Viagra sellers will deliver the pills to your doorstep without requiring a prescription, it is always the safe side to buy Viagra (and any medicine in general) on prescription. First, prescribed medicine will leave better effects since it recommends the right dosage. In case of prescription, your physician has knowledge of your health history. So, in case of any hitch, he can be of quick help. Finally, if you have problems with the pill that cannot be remedied, discontinue its use and go for some other alternative that suits your constitution. Certain herbs and supplements have been shown to perform the role equally well. Search your web for ‘natural alternatives to Viagra’.
Viagra Dosage
The normal dose recommended for most men is 50 mg. Depending on individual response to the drug, the dosage may be increased to 100 mg or brought down to 25 mg. Viagra is taken orally in form of pills or tablets, about one hour before the sexual episode.

How Viagra Works
In sexual arousal of men, more blood flows to the penile tissues, resulting in hardening and erection. The failure to get or maintain an erection is due to the reduction in blood flow to the penis. Viagra is a vasodilator, i.e. it dilates the blood vessels thus increasing blood flow to the penis. Viagra is not an aphrodisiac, meaning it does not play a role in increasing sexual drive or stimulation. In men who are not suffering from ED, Viagra is of little use.
Side effects of Viagra
A number of side effects induced by Viagra intake have been reported. Most common among these are: headache, rash, flushing of face, Diarrhea, nasal congestion, dizziness, abnormal vision, and dyspepsia. Other effects have been reported in different cases.
