Take Vardenafil about 30 to 60 minutes before you plan to have sex. Vardenafil will begin to have an effect in about 30 minutes and last around 4 to 6 hours; Vardenafil can help you get an erection if you are sexually excited. It can be taken with food, unlike Viagra (Sildenafil), but if you take Vardenafil after a high-fat meal (such as a cheeseburger or pizza), the medicine may take a little longer to start working. Vardenafil can help you get an erection when you are sexually excited but you will not get an erection just by taking it alone. Also, you are advised not to drink excessive amounts of alcohol before taking Vardenafil in order to get maximum benefit from taking your medication as drinking alcohol can temporarily affect your ability to get an erection.
Grapefruit juice should not be taken with Vardenafil as it can interfere with the usual effect of the medicine.
