Cialis.

Cialis (tadalafil) can be used to treat erectile dysfunction, although it is not expected to cure it. You must take Cialis only if recommended so by your health care provider. Make sure you do not start using Cialis if you are taking butyl nitrate, isosorbide dinitrate, amyl nitrate, nitroglycerin, isosorbide mononitrate or any other nitrate based drugs. If you are not sure whether the drugs you are using contain nitrates – ask your health care provider or talk to your pharmacist. You will need to inform your doctor of any medical conditions you have that can interfere with your treatment and may require a dose adjustment, such as chest pain, liver, kidney, or heart disease, eye disease, severe vision loss, angulation, irregular heartbeat, a stroke, blood cell problems, cavernosal fibrosis, Peyronie's disease, a heart attack, bleeding disorder, diabetes, ulcers, high or low blood pressure, high cholesterol, and any other ones you think are important to mention. Take Cialis when needed but not more often than every 24 hours. The mild side effects of Cialis are short-lived and unlikely to interfere with your life. The following ones are possible: sore throat, sudden vision loss, stuffy nose, diarrhea, memory problems, headache, upset stomach, warmth or redness in your face, and muscle pain.
