Why is Vardenafil medication prescribed?
Vardenafil is used to treat erectile dysfunction (inability to get or keep an erection) in men. Vardenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. It works by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.
How should Vardenafil medicine be used?
Vardenafil comes as a tablet and a rapidly disintegrating (dissolves in the mouth and is swallowed without water) tablet to take by mouth. It is usually taken as needed, with or without food, 60 minutes before sexual activity. Vardenafil usually should not be taken more often than once every 24 hours. If you have certain health conditions or are taking certain medications, your doctor may tell you to take vardenafil less often. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vardenafil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you are taking the rapidly disintegrating tablet, check the blister pack before you take your first dose. Do not use any of the medication from the pack if any of the blisters are torn, broken, or do not contain tablets. Follow the package directions to remove the tablet from the blister package. Do not try to push the tablet through the foil. After you remove the tablet from the blister package, immediately place it on your tongue and close your mouth. The tablet will quickly dissolve. Do not take the rapidly disintegrating tablet with water or other liquids.
Your doctor will probably start you on an average dose of vardenafil tablets and increase or decrease your dose depending on your response to the medication. If you are taking the rapidly disintegrating tablets, your doctor will not be able to adjust your dose because the rapidly disintegrating tablets are only available in one strength. If you need a higher or lower dose, your doctor may prescribe the regular tablets instead. Tell your doctor if vardenafil is not working well or if you are experiencing side effects.
Vardenafil rapidly disintegrating tablets cannot be substituted for vardenafil tablets. Be sure that you receive only the type of vardenafil that was prescribed by your doctor. Ask your pharmacist if you have any questions about the type of vardenafil you were given.
