VastRX Cialis Information

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

How should Cialis be used?
Cialis comes as a tablet to take by mouth. It is usually taken with or without food before sexual activity. Your doctor will help you decide the best time for you to take Cialis before sexual activity. Cialis 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 Cialis 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 Cialis 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 Cialis and increase or decrease your dose depending on your response to the medication. Tell your doctor if Cialis is not working well or if you are experiencing side effects.

Other uses for Cialis
Cialis may be prescribed for other uses; ask your doctor or pharmacist for more information.
