Cialis warnings

Categories: Cialis

FDA considers it urgent to warn the patients who use Cialis containing tadalafil about its rare serious side effects including vision and hearing loss and priapism.

These FDA warnings appeared after several reports of serious side effects mostly in patients with preexisting health conditions.

Tadalafil can reduce blood flow to the optic nerve of the eye and cause sudden vision problems including vision loss in one or both eyes. The events of sudden vision loss were observed in small group of patients with such disorders as heart disease, diabetes, and hypertension. Patients who experience this serious side effect should stop the usage of Cialis and call a doctor. An event of sudden vision loss may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION). Patients who have already had NAION in one or both eyes should not use Cialis.

Patients with hereditary degenerative retinal disorders (eye problems) including retinitis pigmentosa can be seriously affected by PDE5 inhibitors, so they should not use any of them.

Tadalafil may cause sudden hearing loss. In cases of this side event patients should stop using Cialis and seek emergency medical attention.

There have been rare reports of priapism condition (prolonged and painful erections longer than 4-6 hours) in patients mostly who had certain blood diseases. Priapism is a serious condition requiring quick medical help; otherwise it may cause permanent damage to the penis. In case a person experiences this condition he should get medical help right away.
