Cialis

Cialis (tadalafil) is a medicine efficient for most patients diagnosed with erectile dysfunction. It provides for up to 36 hours of efficiency, although this period may vary depending on a number of factors. Before you start taking Cialis you are supposed to let your doctor know about any health problems you have or experienced in the past, as well as what drugs you are taking at the moment. For instance, taking nitrate-based drugs (usually prescribed for the treatment of chest pain) is a direct contraindication for taking Cialis or any other erectile dysfunction medicine. Taking nitrate-based drugs along with Cialis may result in a sudden drop in blood pressure, fainting and even death. It’s important that you follow all of your doctor’s directions and consult your health care provider if you think some changes need to be made.
