Use tadalafil exactly as directed by your doctor. Do not use more of it and do not use it more often than your doctor ordered. If too much is used, the chance of side effects or other problems is increased.
You may take this medicine with or without food.
The ability to have sexual activity may be improved for up to 36 hours after taking tadalafil.
