When it comes to medication, recommended dosages exist for a very good reason!
As a 31-year-old man recently found out, after he was rushed to hospital two days after taking a little too much Viagra, reports iflscience.
The man was reportedly suffering red-tinted vision, a condition that's irreversible.
A study led by Mount Sinai which is due to be published in the journal Retinal Cases, confirms that sildenafil citrate (Viagra) can permanently damage vision.
"People live by the philosophy that if a little bit is good, a lot is better," Richard Rosen, director of Retina Services at New York Eye and Ear Infirmary of Mount Sinai (NYEE) and lead investigator, said in a statement.
"This study shows how dangerous a large dose of a commonly used medication can be."
Rosen and his team examined the retina of the 31-year-old man to check for severe damage.
Significant damage.
And they found some significant damage.
The man's retina showed damage comparable to that found in animal models of hereditary retinal diseases like, for example, cone-rod dystrophy – which was unexpected, the researchers say.
"[I]t explained the symptoms that the patient suffered from," Rosen added.
"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."
The man is now one year on since his first diagnosis and his vision has not improved.
Treatments haven't helped and medics say the damage is irreversible.
Moral of the story... don't take too much Viagra.
