Why can Viagra cause vision problems?

The drug "Viagra", which is in the scientific communitybetter known as sildenafil, it is considered the most popular treatment for erectile dysfunction in men. Its popularity is due to the fact that it effectively copes with its task and in most cases does not have any side effects. However, recently a Turkish ophthalmologist Junite Karaarslan shared that in some cases this drug can cause vision problems. Such a side effect can prevent men from driving and coping with their tasks at work, so scientists believe that everyone should know about the possible consequences of taking the medicine. This is a very true statement, because vision problems can haunt men for three days.

Viagra can cause vision problems

The new side effect of Viagra was described inthe scientific journal Frontiers in Neurology. You probably already know that sildenafil was originally created as a remedy for high blood pressure. However, it soon became clear that his ability to dilate blood vessels also helps men maintain an erection. Typically, the duration of Viagra is about five hours. In this case, headache and other side effects are extremely rare. Unless, of course, do not exceed the used dose of the drug.

Side effect of Viagra

The aforementioned ophthalmologist Junith Karaarslanshared that during his work at least 17 men who complained of vision problems turned to him. In particular, they were worried about a blurred image, increased sensitivity to light and color distortion. For example, many of them thought that the blue colors became much brighter, and the red and green hues began to look different.

By the way, Viagra is one of 18 random scientific inventions and discoveries that changed the world.

During conversations with patients, the doctor found outthat they all recently consumed Viagra. It is noteworthy that many of them drank the medicine for the first time, and the maximum recommended dose is 100 milligrams. Vision problems began almost immediately after taking the drug and lasted for three days. Since men had blurred vision and perceived colors incorrectly, they were contraindicated in driving a car.

Because of Viagra, men may perceive colors differently.

According to scientists, strong side effects fromViagra can occur due to the fact that in some people the drug is broken down for a long time and excreted from the body. Since the patients of the ophthalmologist took a large dose, there was a lot of sildenafil in their blood, which also stayed there for several days. Also, unwanted effects may occur in those who take the drug for the first time. They should not drink a large dose immediately, but start gradually. Of course, before using it is better to consult with your doctor.
