Cialis.

Cialis (tadalafil) is a medicine specially intended for patients suffering from erectile dysfunction it works by stimulating blood flow on the tissues of the penis helping you to maintain the erection for longer. You may need to take this medicine as needed or go for the form of Cialis that is taken regularly. This drug is never supposed to be combined with nitrates – drugs such as butyl nitrate, amyl nitrate, isosorbide dinitrate, nitroglycerin, or isosorbide mononitrate, as this may result in very serious consequences – stroke, fainting or even death. Inform your health care provider of the fact of using any other medications, especially amiodarone, rifabutin, erythromycin, nefazodone, diltiazem, rifampin, sertraline, other erectile dysfunction treatments, ethosuximide, phenobarbital, carbamazepine, cimetidine, efavirenz, zafirlukast, alpha blockers, danazol, isoniazid, medications for high blood pressure, clarithromycin, HIV protease inhibitors, metronidazole, lovastatin, delavirdine, or antifungals, as interactions have been reported. Always take as much of Cialis as prescribed – as using more is not going to give you erections that are more powerful.
