Cialis® (
tadalafil) is approved for the treatment of
erectile dysfunction (also known as
ED or
impotence). It is also approved to treat
enlarged prostate symptoms. Most men tolerate the medication without any problems; however, there are some potential dangers with Cialis to be aware of. For example, it may cause serious side effects, such as a severe allergic reaction or an erection lasting longer than four hours, that often require prompt medical attention.
In addition, Cialis can be dangerous to men with certain medical conditions or who are taking certain other medications. For example, men who have a history of
heart disease may be more likely to experience problems with Cialis. Men who are taking a nitrate for
angina may need to take a different
erectile dysfunction medication.
To ensure a safe, effective treatment process, tell your healthcare provider about all medicines you are taking, including vitamins, supplements, and nonprescription products, and provide a complete medical history, detailing any other medical conditions you have.
