Cialis

Cialis (tadalafil) is an oral drug that is used for treating impotence (erectile dysfunction, ED). It is in a class of drugs called phosphodiesterase inhibitors. The most common side effects of Cialis are facial flushing (reddening), headaches, stomach upset, diarrhea, flu-like symptoms, and nausea. Cialis also may cause low blood pressure, blurred vision and changes in color vision, abnormal ejaculation, and priapism.

The recommended dose of Cialis is 5-20 mg per day taken before sexual activity. The breakdown and elimination of Cialis from the body may be decreased by erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir). Therefore, these drugs may increase the levels of Cialis in the blood. Cialis exaggerates the increases in heart rate and lowering of blood pressure caused by nitrates (for example, nitroglycerin, isosorbide dinitrate (Isordil), isosorbide mononitrate (Imdur). Cialis is not approved for use in women and has not been evaluated in women who are breastfeeding.
