How long does Levitra last?
Approved by the FDA in 2003, Levitra has as its active ingredient vardenafil hydrochloride and is another member of the PDE5 inhibitor family. The pill is available in varying strengths, ranging from 2.5 milligrams to 20 milligrams. If you have not previously used the drug, you may have to try different strengths to determine which is most effective for you. Your doctor will probably start you at a 10-milligram dose and then make adjustments upward or downward if the initial level of medication is either less or more than you need for optimal function.
The pill should be taken roughly an hour before sexual activity, and no more than a single pill should be taken during a 24-hour period. Levitra typically is effective for up to four hours after the pill is taken. However, Drugs.com reported on a study that showed Levitra’s effects last as long as 12 hours for some users.
