In ED, a man's erection is characterized by:
- the inability of the penis to harden and expand when the man is sexually excited
- the inability to keep an erection
If so, you are not alone. It is estimated that up to 30 million men in the United States have experienced at least some degree of ED.
If you've noticed changes in your erections, there is something you can do about it.
Cialis (tadalafil) relaxes muscles and increases blood flow to particular areas of the body.
Cialis is used to treat erectile dysfunction (impotence) in men. Adcirca, another brand of tadalafil, is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women.
Cialis may also be used for purposes other than those listed in this medication guide.
