What We Know
Viagra boosts blood flow by turning off an enzyme called phosphodiesterase 5. But in the process, the drug also meddles with a related enzyme in retinal cells. At high doses, experts say, this could permanently damage the retina. Side effects most often emerge in men with other underlying health conditions such as high blood pressure or heart conditions. Erectile dysfunction drugs are tied to ischemic optic neuropathy, a sudden and permanent vision loss caused by interrupted blood flow to the optic nerve. This in fact is most common in men with high blood pressure or heart conditions.
While the report raises concerns, experts do not recommend discarding the drug. One key takeaway: Only use ED medicine under medical supervision, and at a prescribed dose!. Also, purchase the drug from a trusted source. Counterfeit drugs, often sold online, are not regulated by the FDA and may not meet quality and safety standards.
