If you need emergency medical care for a heart problem, it will be important for your healthcare provider to know when you last took CIALIS.After taking a single tablet, some of the active ingredient of CIALIS remains in your body for more than 2 days. The active ingredient can remain longer if you have problems with your kidneys or liver, or you are taking certain other medications (see “Can Other Medicines Affect CIALIS?”).Stop sexual activity and get medical help right away if you get symptoms such as chest pain, dizziness, or nausea during sex.

Physicians should advise patients who have an erection lasting greater than 4 hours, whether painful or not, to seek emergency medical attention. Physicians should also discuss with patients the increased risk of NAION in individuals who have already experienced NAION in one eye, including whether such individuals could be adversely affected by use of vasodilators such as PDE5 inhibitors [see Clinical Studies (6.2)]. Therefore, physicians should inform patients that substantial consumption of alcohol (e.g., 5 units or greater) in combination with CIALIS can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache [see Warnings and Precautions (5.9), Drug Interactions (7.1), and Clinical Pharmacology (12.2)]. Counseling of patients about the protective measures necessary to guard against sexually transmitted diseases, including Human Immunodeficiency Virus (HIV) should be considered. CIALIS is available in two dosing regimens; therefore, physicians should instruct patients on the appropriate administration to allow optimal use. For CIALIS for use as needed, patients should be instructed to take one tablet at least 30 minutes before anticipated sexual activity. In most patients, the ability to have sexual intercourse is improved for up to 36 hours.
