Uses

TADALAFIL (Cialis) is used to treat erectile dysfunction (ED) in men. Tadalafil does not cure ED or increase a man's sexual desire. Tadalafil is only for men with ED and is not for women or children. Tadalafil should only be used under a health care provider's care. Generic tadalafil is not yet available.

How to Use

Take tadalafil tablets by mouth. Follow the directions on the prescription label. The dose is usually taken 30 minutes to 1 hour before sexual activity. You should not take this dose more than once per day. Swallow the tablets with a drink of water. You may take tadalafil with or without meals. Do not take double or extra doses. Do not change your dose without talking to your prescriber. Your prescriber may lower or raise your dose, depending on how your span reacts to tadalafil. If you have kidney or liver problems or are taking certain medications, your prescriber may limit your dose of tadalafil. Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed. At this time, this medicine is not for use in children.

Side Effects

Side effects that you should report to your prescriber or health care professional as soon as possible:changes in vision, chest pain or palpitations, difficulty breathing, shortness of breath, dizziness, eyelid swelling, prolonged erection (lasting longer than 4 hours), skin rash, itching. Side effects that usually do not require medical attention (report to your prescriber or health care professional if they continue or are bothersome):back pain, flushing, headache, indigestion, muscle aches, stuffy or runny nose.

Precautions

Contact your physician immediately if the erection lasts longer than 4 hours or if it becomes painful. This may be a sign of priapism and must be treated immediately to prevent permanent damage.

Drug Interactions

If you experience symptoms of nausea, dizziness, chest pain or arm pain upon initiation of sexual activity after tadalafil use, you should refrain from further activity and should discuss the episode with your prescriber or health care professional as soon as possible. Do not drink alcohol to excess (examples, 5 glasses of wine or 5 shots of whiskey) when taking tadalafil. When taken in excess, alcohol can increase your chances of getting a headache or getting dizzy, increasing your heart rate or lowering your blood pressure.

Please call your prescriber or health care professional to determine if your dose needs to be reevaluated. Using tadalafil does not protect you or your partner against HIV infection (the virus that causes AIDS) or other sexually transmitted diseases.
