CIALIS is not for everyone. If you take nitrates, often used for chest pain (also known as angina), or alpha-blockers (other than Flomax 0.4 mg once daily), prescribed for prostate problems or high blood pressure, do not take CIALIS. Such combinations could cause a sudden, unsafe drop in blood pressure. Don't drink alcohol in excess (to a level of intoxication) with CIALIS. This combination may increase your chances of getting dizzy or lowering your blood pressure. CIALIS does not protect a man or his partner from sexually transmitted diseases, including HIV.
The most common side effects with CIALIS were headache and upset stomach. Backache and muscle ache were also reported, sometimes with delayed onset. Most men weren't bothered by the side effects enough to stop taking CIALIS. Although a rare occurrence, men who experience an erection for more than 4 hours (priapism) should seek immediate medical attention. Discuss your medical conditions and medications with your doctor to ensure CIALIS is right for you and that you are healthy enough for sexual activity.
*Individual results may vary. In clinical trials, CIALIS was shown to improve, up to 36 hours after dosing, the ability of men with ED to have a single successful intercourse attempt. CIALIS has not been studied for multiple sexual attempts per dose.
