Erectile dysfunction (impotence) means that men have difficulty getting and maintaining an erection during sexual intercourse. About 70% of men suffer from erectile dysfunction. But now you can get better with vilitra 40. Taking this pill improves blood flow in and around the male penis. This gives them a better erection during sex and they can enjoy sex for a long time. For effective results take this medicine 30-40 minutes before intercourse. Also, you should take only one pill in 24 hours because if you take more doses you will have side effects. Also, if you are currently suffering from a heart attack/stroke, you should inform your doctor before taking this medicine.
