Rare side effects of Cialis

Some persons stop to distinguish colors, such as blue and green. This side effect happens with the patients who suffer from a visual contrast sensitivity and color perception. Visit your physician and ophthalmologist to get an advice concerning the dosage and frequency of taking Cialis.

As Cialis acts very vigorously “taking” much blood to penis, less blood flow comes to heart and can cause heart troubles. The instruction says that patients with heart diseases should not use the medicine. Those men, who never had pains in heart, should also take Cialis with precaution. Do not ever mix alcohol and this drug. Never take nitroglycerin and Cialis, as your blood pressure will fall critically.
