When it comes to medicine for sexual disability, the two primary drugs that are in close competition are Levitra vs Viagra. Because of this, many users wonder at which points do these two medicines either meet or differ in order to decide if they should go for the other drug or not.

To begin, Viagra or the little blue pill can be taken in three different doses of twenty five, fifty and one hundred milligrams each and must also be taken half an hour to four hours before sexual intercourse. Some of the usual adverse effects of Viagra involve sneezing, flushing, headaches, heartburn, feelings of dizziness, dyspepsia, extreme sensitivity to light and photo phobia. There are also some serious side effects of taking Viagra, and these usually are priapism (an erection that remain even four hours after intercourse), stroke, heart attacks, sudden death or low blood pressure. The effects of Viagra may be felt inside forty-five minutes after you take the medicine, and can be effective for hours.
