LEVITRA (vardenafil) is a prescription medication used to treat ED (erectile dysfunction, the inability to attain or maintain a penile erection). You will not get an erection just by taking this medicine. LEVITRA helps a man with ED get and keep an erection only when he is sexually stimulated and it usually starts to work within approximately 60 minutes. It works by increasing blood flow to the penis to help improve erectile function. Do not take more than one LEVITRA per day and doses should be taken at least 24 hours apart. This product is not for use in women or children.
