While taking

Tadalafil is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Tadalafil 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. Tadalafil does not cure erectile dysfunction or increase sexual desire. Tadalafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).

Tadalafil comes as a tablet to take by mouth. It may be taken with or without food.

There are two different ways to take tadalafil. Talk to your doctor about which dosing schedule is right for you. It is sometimes taken as needed before sexual activity, not more often than once every 24 hours. Your doctor will help you decide the best time for you to take tadalafil before sexual activity. Tadalafil is also sometimes taken once a day every day without regard to timing of sexual activity. You may attempt sexual activity at any time between doses. If you are taking tadalafil on a regular schedule, take it at around the same time every day. If you have certain health conditions or are taking certain medications, your doctor may tell you to take tadalafil less often or may prescribe a lower dose to be taken once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tadalafil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on an average dose of tadalafil and increase or decrease your dose depending on your response to the medication. Tell your doctor if tadalafil is not working well or if you are experiencing side effects.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
