One man’s expertise with a typical erectile dysfunction drug turned out to be much more eye-opening than he anticipated. According to his docs, he developed a seemingly everlasting crimson tint to his colour imaginative and prescient after taking a large dose of sildenafil citrate.

Sildenafil is bought as a generic drug for erectile dysfunction in addition to beneath the model identify Viagra. Despite being comparatively protected, even a sometimes prescribed dose of sildenafil is thought to generally trigger individuals imaginative and prescient issues, comparable to blurred imaginative and prescient, elevated gentle sensitivity, and a change in our colour imaginative and prescient (often blue-tinted imaginative and prescient). But these issues are seemingly non permanent, often lasting not more than a day.

The 31-year-old man, whose case was detailed in a report published this month in Retinal Cases, didn’t turn into so fortunate.

According to the report, the person’s troubles started fairly quickly after he took an unknown quantity of liquid sildenafil he had bought from the web. He started seeing multicolored flashes of sunshine, his eyes turned extra delicate to gentle, and his imaginative and prescient took on a reddish tint. By the time he visited an pressing care clinic on the New York Eye and Ear Infirmary of Mount Sinai two days later, the flashes had stopped. But regardless of receiving therapy, his crimson tint has remained in place for greater than a yr.

The man didn’t measure out the dose of sildenafil he took—opting as a substitute to chug it straight from the bottle—so there’s no telling how a lot was in his system. But it’s nearly sure he took far more than the really helpful dose of 50 milligrams, in line with the docs.

“People live by the philosophy that if a little bit is good, a lot is better. This study shows how dangerous a large dose of a commonly used medication can be,” lead writer Richard Rosen, director of Retina Services on the New York Eye and Ear Infirmary of Mount Sinai, mentioned in a statement. “People who depend on colored vision for their livelihood need to realize there could be a long-lasting impact of overindulging on this drug.”

There’s proof in each animals and people that taking a heavy dose of sildenafil could be particularly damaging to the eyes, in line with analysis cited by the authors. And the drug has been linked (although not conclusively) to uncommon circumstances of imaginative and prescient loss. But Rosen and his group imagine they’re the primary to doc how sildenafil is able to harming our colour imaginative and prescient, because of extra not too long ago developed imaging strategies used at Mount Sinai.

These strategies, in line with the report, revealed that the person’s cones—a sort of cell within the retina that enables us to understand colour—had been broken on a microscopic stage by the drug. The sample of injury, they added, was just like that seen in different genetic issues involving the retina, comparable to colour blindness. Other analysis has suggested that individuals with mutations related to these issues may be at a higher danger of eye issues in the event that they take sildenafil.

“To actually see these types of structural changes was unexpected, but it explained the symptoms that the patient suffered from. While we know colored vision disturbance is a well-described side effect of this medication, we have never been able to visualize the structural effect of the drug on the retina until now,” mentioned Rosen. “Our findings should help doctors become aware of potential cellular changes in patients who might use the drug excessively, so they can better educate patients about the risks of using too much.”

Because the drug was bought on-line, Rosen and his group can’t rule out the likelihood {that a} contaminant may need additionally contributed to the person’s unlucky destiny. Still, it’s not like telling somebody to ease off the ED medication a bit is a foul thought within the first place. Sildenafil’s different side effects when used too closely can embody coronary heart assault and painfully long-lasting erections that, if untreated, may even trigger your penis to develop gangrene and require amputation.
