Does Viagra have Any Side Effects?

Viagra is a wonder drug which is known to aid in erectile dysfunction in men. However, one must not forget that no drug is perfect and this holds true for Viagra too. It works by eliminating the PDE which decomposes the cGMP in the penis. Hence, it facilitates the build up of cGMP in your penis and exerts a greater effect on the walls of the arteries. If the quantity of cGMP is higher, there is a consequent effect on your blood circulation which is increased as well. With enhanced blood flow, you tend to experience a better erection.

Users of Viagra should be prepared for the side effects of the wonder drug. Some of them have been enlisted as follows:

  • Spillover Effect: The primary side effect of Viagra stems from the spillover reaction that this drug seems to have. It works by blocking the PDE5, although it exerts a similar effect on PDE6 as well. The PDE6 is generally utilized within the cone cells of the retina which implies that Viagra can exert an effect on the color vision. Different people who take the drug have reported a change in their perception of the colors blue and green, or report an effect of blue on all the objects that they view for up to several hours. This is why pilots are not recommended to take Viagra within 6 hours of flight.
  • Risk of Angina: People who take drugs such as nitroglycerin for angina are not advised to take the medication. The effects of nitroglycerin are realized by enhancing the levels of nitric oxide which stimulates angina by opening the arteries which bring in oxygen to the heart. If Viagra is taken with nitroglycerin, the blocking of the PDE5 and enhanced levels of nitric oxide may react to create problems.
  • Headache: This is a common side effect as Viagra opens the arteries within the lining of the brain to lead to excessive pressure. At times, the side effects may even lead to heart attacks and the chances of experiencing one are responsible for Viagra being a prescription drug instead of being available over the counter such as aspirin. The doctor before recommending Viagra should be informed about your medical record and ensure that the drug will not lead to a heart attack.
  • Painful Erection: One of the most famous side effects of Viagra includes a painful and long lasting erection. Some men have reported experiencing painful erections for up to several hours.
  • Dependency Issues: Another concern with using Viagra is that men, particularly those who are young and take Viagra for recreational purposes without requiring it for physical purposes, may experience a dependency. It has also been observed that they may not be able to maintain their erection without taking the drug.

This is why men are advised to take Viagra with caution and not on a random basis. It is best to seek the consultation of a doctor before using it for recreational purposes.
