Cialis is used to treat erectile dysfunction in men. This is when a man cannot get, or maintain, an erect penis suitable for sexual activity.
Cialis is not intended for use by women.
Cialis belongs to a group of medicines called phosphodiesterase type 5 inhibitors.
Following sexual stimulation, Cialis works by helping blood vessels in the penis to relax. This allows blood to flow into the penis, thereby producing an erection.
Cialis will only work if you are sexually excited.
Cialis will not help you if you do not have erectile dysfunction.
Cialis is available only with a doctor's prescription.
There is not enough information to recommend the use of this medicine for subjects under the age of 18 years.
