Side Effects of Tadalafil
Some common side effects of tadalafil include facial flushing, nasal congestion, and pain in the arms or legs. A few rare tadalafil side effects include a spinning sensation (vertigo), high blood pressure, and angina. Let your healthcare provider know if you develop any side effects, as well as anything that "just doesn't seem right," while taking tadalafil.
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.

Please note that this article refers specifically to Cialis, the original tadalafil product that is approved for treating erectile dysfunction.
