Side Effects of Tadalafil: An Introduction
As with any medicine, there are possible side effects with
Tadalafil (
Cialis®). However, not everyone who takes tadalafil will experience side effects. In fact, most people tolerate tadalafil well. When people do develop tadalafil side effects, in most cases they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider. In previous research studies, up to 3.1 percent of people on tadalafil stopped taking their medicine because of side effects.
(The tadalafil side effects listed below are not a complete list of side effects reported with tadalafil. Your healthcare provider can discuss a more complete list of side effects with you.)
