The medicine will not increase your desire for sex. That’s on you. Vardenafil relaxes the blood vessels that supply your penis, allowing more blood flow to the area to help you maintain a firmer erection during sex.
HOW TO USE VARDENAFIL
The usual starting dose is 10mg taken about 25 to 60 minutes before sex. The tablet should be swallowed whole with a little water. Taking the tablet with a meal, particularly a high fat meal, may delay its absorption and it could take longer to work.
HOW LONG DOES VARDENAFIL LAST?
Vardenafil is usually taken 25 minutes to an hour before sex and it only works if you are sexually aroused. Vardenafil may remain effective for up to 4-5 hours after taking it. Some foreplay prior to sexual activity is required. Then the erection will go away as it usually does after sex.
