Cialis.

Cialis (tadalafil) is an anti-impotence medicine that has been used for many years to treat male impotence, also called erectile dysfunction. This drug must never be combined with nitrates – such drugs as isosorbide dinitrate, nitroglycerin, amyl nitrate, isosorbide mononitrate, butyl nitrate, and some other ones. The combination may result in a sudden drop in blood pressure and you will need to seek emergency medical help when you get some of the symptoms. Therefore, make sure you tell your doctor if you are using any nitrates, or other medications, especially antifungals, other erectile dysfunction treatments, metronidazole, isoniazid, clarithromycin, phenobarbital, diltiazem, cimetidine, lovastatin, medications for high blood pressure, sertraline, efavirenz, erythromycin, nefazodone, ethosuximide, delavirdine, zafirlukast, carbamazepine, danazol, rifampin, alpha blockers, HIV protease inhibitors, rifabutin, or amiodarone. This is not the full list of drugs that have been reported to cause interactions with Cialis – you will be able to learn more from your health care provider. Always take Cialis as recommended and do not exceed the dose. The following symptoms are possible if you take more of Cialis than necessary: heartburn, indigestion, priapism, headache, pain in the back, stuffy or runny nose, muscle pain, and flushing. They need to be reported to your emergency center.
