Cialis.

Cialis (tadalafil) is a potent prescription PDE5 inhibitor used for the treatment of erectile dysfunction. It is intended for males only and is not supposed to be taken by females. Certain amount of sexual stimulation is required if you want Cialis to work for you – otherwise this medicine is unlikely to cause the effects desired. Before starting the treatment tell your doctor if you are allergic to any drugs or foods to make sure Cialis is going to be safe for you. Also inform your doctor of any medical conditions you have to used to have, such as sickle cell anemia, penis angulation, recent stroke, kidney disease, blood system cancers, liver disease, active stomach ulcers, coronary artery disease, history of painful/prolonged erection, Peyronie's disease, bleeding disorders, fibrosis/scarring, or pre-existing eye problems, as those may negatively affect the success of your treatment and get worse. Cialis is not supposed to be taken on the regular basis unless it’s a special form of this medicine intended for regular use. Never take more of Cialis than recommended, as this may result in a number of symptoms that will need to be reported to your health care provider as soon as possible. The following symptoms may be experienced: pain in the back, flushing, stuffy or runny nose, headache, indigestion, chest pain, erection that lasts longer than 4 hours, and heartburn.
