Levitra is an oral drug used to treat impotence and improve the sexual activity for men. Levitra works by increasing the blood flow in the penis resulting in an erection. It is offered in two dosages: Levitra 10mg and Levitra 20mg. The 2.5mg and 5mg dosages are available in the market, but the 10mg and 20mg have a better value for our customers. We don't offer the 2.5mg nor the 5mg dosage. A lot of men who have taken Levitra were happy from the first results that the orange tablet has given them.
