Most of the side effects of Viagra are harmless. They are uncommon as well. The number of serious side effects to using these medicines is pretty low and they are rarer. Among them is a vision problem called NAION. It seems very likely that the label of this ED drug will be updated to contain a warning for this disorder.

Moreover, as a treatment for erectile dysfunction, this drug has been proven to be quite effective. Millions of ED patients have been benefited from this medicine.

NAION stands for nonarteritic anterior ischemic optic neuropathy. It is a rare condition that affects the optic nerve in the eyes. In this condition, the optic nerve swells up. As a result, the patient begins to lose vision in a very short period of time.

Pfizer reviewed 103 clinical trials of their medicine. Over 13,000 patients were involved. Among them, there was no reported case of NAION. However, NAION has been reported in 14 men who were using Viagra for their ED problems. Currently, millions of people use this drug. As a result, there is no evidence that proves that using this medication increases the risk of developing NAION.
