Vardenafil belongs to the class of medications called phosphodiesterase type 5 inhibitors. It is used to treat erectile dysfunction (male impotence). It helps to achieve penile erection sufficient for sexual activity to occur. It does this by allowing a greater blood flow into the penis when a man taking the medication is sexually aroused. It works only with sexual stimulation and does not increase sexual desire.

How should I use Levitra?
The usual recommended dose is one 10 mg tablet taken as needed, at least 25 minutes before sexual activity. This medication has been shown to be effective within 15 minutes of taking the tablet, and lasts up to 10 hours later. As the amount of time vardenafil takes to work varies from person to person, starting sexual activity at different times after taking the tablet will determine the optimal time for sexual activity. It is not recommended to take more than one dose per day.
