Man Took Too Much Viagra That He Started Seeing Red… Permanently

He drank the drug straight from the bottle More

(It's commonly sold under the brand name Viagra.) His story was published this month in Retinal Cases & Brief Reports. But despite receiving treatment for more than a year, the man continues to experience red-tinted vision.

These techniques enabled the researchers to see microscopic injuries to the cones-one of the three types of photoreceptive cells in the retina of mammalian eyes-which are responsible for color vision.

More specifically, the guy took sildenafil citrate in its liquid form, which is also the active compound in the popular Viagra potency drug.

The man sought care at an urgent care clinic after suffering from red-tinted vision for two days, according to a statement about the case released by the Mount Sinai Health System in NY. They ultimately diagnosed him with persistent retinal toxicity caused by the high dose of sildenafil citrate. In a case study, doctors from Mount Sinai in New York City say the case illustrates that excessive use of the drug could lead to long-term, possibly irreversible damage. "This study shows how unsafe a large dose of a commonly used medication can be". Visual changes are a known potential side effect of sildenafil citrate at the approved dose, but generally resolve within 24 hours.

The telephoto camera is a 13 MP one with f/2.4 aperture, and the third camera is a 16 MP wide-angle sensor with a 123-degree FoV. As the primary will set the sensor at 24 MP with aperture of f/1.7 and a system of optical image stabilization.

Side effects of the drug include sensitivity to light and changes in color vision.

The popular erectile dysfunction drug has seen its fair share of headlines, but this freakish case is certainly one for the books. He is lucky that he did not go blind, as Viagra has been linked to rate cases of vision loss, but the red tint in his vision will likely serve as a reminder of his unsafe usage of the erectile dysfunction drug.

But the takeaway message is still the same. "This study shows how risky a large dose of a commonly used medication can be", lead investigator Dr. Richard Rosen, director of retina services at New York Eye and Ear Infirmary of Mount Sinai, said in the statement. Follow INSIDER on Facebook.
