The biggest question used to be what Viagra is, but now everyone knows what it is. Now they want to know how they can get some! To get Viagra you do need a prescription. You do have choices though, you can go see your doctor and discuss it with him. If he decides that you likely have erectile dysfunction then he will write you a prescription for Viagra. If you don’t care for that option then you can go online to a reputable pharmacy. You will know if the online pharmacy is reputable because they will have a staff physician that will review your medical history that you will have to fill out first and it can be dispensed that way.

Many also are curious just exactly how Viagra works. An erection is achieved by an increase in blood flow to the penis. Viagra works by allowing the chemicals that the body releases into the penis when there is sexual arousal. The result is an increase of blood flow into the penis. Another big question is what is the cost? Many patients want Viagra which runs over $12 a pill and most insurance companies do not cover this drug.

Some people want to know if it is alright to take a combination of ED drugs at the same time. The answer is simply, no. Ok, finally the big question, how long does Viagra take to work? Give it about an hour and it is good for about 4 hours afterwards.
