What is vardenafil used for?

The maximum dose of LEVITRA for which human data are available is a single 120 mg dose administered to eight healthy male volunteers. The majority of these subjects experienced reversible back pain/myalgia and/or “abnormal vision.” In cases of overdose, standard supportive measures should be taken as required.
