Cialis (tadalafil) is one of the three most popular medicines intended for the treatment of male impotence. This medicine works in the most natural way – helping the blood vessels in the penis to dilate, filling with blood, and preventing the blood from escaping back into the body, which is one of the causes of erectile dysfunction. Take Cialis when needed, about 30 minutes before planned sexual activity with a glass of water, without sucking or chewing the tablet. Avoid drinking grapefruit juice as it has been reported to interact with Cialis making it less efficient. If you are taking nitrate drugs for chest pain, make sure your doctor is aware of that before giving you the prescription.

Certain health conditions can make it impossible for you to take Cialis or your dose will need to be adjusted. Such conditions include kidney or liver problems, stomach ulcer, angina, irregular heartbeat, a recent history of a heart attack, or an inherited retinal disorder. Some other conditions (leukemia, multiple myeloma or sickle cell anemia) can increase the risk of developing serious side effects, including priapism (long and painful erection fraught with permanent damage of your penis tissues). Cialis does not protect you from sexually transmitted disease. You should use a condom every time when you have sex.
