This has occurred among a small percentage of those taking sildenafil (Viagra) or similar drugs to Avanafil.Most of these people also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, including those who smoked or were over 50 years old. Unconfirmed reports point towards Avanafil as being responsible for vision loss.Avanafil is for use only by men. No data exists to demonstrate whether Avanafil would cause harm if taken during gestation or breast-feeding by women.
