Levitra (vardenafil hydrochloride) is specially intended for the treatment of male impotence, the exact term for which is erectile dysfunction. Levitra can be taken about 40 minutes before you are going to have sex and since the moment of becoming efficient it’s expected to provide you with up to 5 hours of efficiency. This period may be slightly different for different people - so the sooner you have sex after Levitra becomes efficient – the better. Make sure you inform your health care provider of any diseases you have or used to have that may potentially affect the success of your treatment. The following ones are important to report as additional tests may be required to establish the safety of taking Levitra: ulcers in the stomach or intestine, irregular heartbeat, high or low blood pressure, Peyronie's disease, stroke, diabetes, bleeding disorder, cavernosal fibrosis, heart attack, blood cell problems, liver, kidney, or heart disease, as well as chest pain. In some very rare cases Levitra can cause serious side effects, such as sudden vision loss and priapism (prolonged and painful erection). Make sure you talk to your doctor before the treatment for your personal risks to be assessed.
