Unfortunately, medicine is not perfect, and Viagra is no different. The majority of people will never experience a side effect in their life, while others may be unlucky enough to experience one per every medication they use. In this guide, we will explore a bit more about the side effects of Viagra.



Colour Vision

To operate, Viagra blocks the PDE5, but can also affect the PDE6 (which affects the way we see light). Quite a few people notice a small change in the way they see green and blue while taking Viagra, while others may notice more severe changes. This side effect is not permanent; therefore, it is really your choice if you want to make your doctor aware.

Problems with colour are mostly associated with those that take Nitroglycerin and Viagra at the same time. This is because they interact with one another. The Nitroglycerin increases Nitrous Oxide and the Viagra blocks the PDE5, and both can lead to problems with seeing colour. This is a problem that doctors are aware of, and they will probably advise against taking the two together. This is why you should always tell your doctor what medication you are taking.

Heart Attacks

In extremely rare circumstances the way Viagra operates can cause problems with the heart or even heart attacks. However, this is why you cannot buy it over the counter and need to have it prescribed. When you visit the doctor, always be 100% honest with any problems you may have or medications/supplements that you are taking at the time. If a doctor has just 0.01% doubt that Viagra could cause you a heart attack, then they will not prescribe this medication.

Headaches

A lot of people taking Viagra complain about headaches because the medication 'opens up' some of the arteries in the brain which causes pressure. This is a problem that will pass when you stop taking the medication, and it is up to you if you tell your doctor about them.

Painful or Long Lasting Erections

If you are taking Viagra and the effect lasts longer than four hours, then you need to see a medical official right away because there could be a problem. Furthermore, if your erection is painful then you should do the same. If you do not see a doctor immediately then this can lead to long lasting damage of the penis.

Addiction

Viagra is now being taken recreationally by young men who believe they need to use it in order to gain an erection. Unfortunately, breaking the habit and reverting off Viagra can be extremely hard because of the mental stresses that one is put under when no longer using Viagra. On the other hand, those who only use it when needed, or those who know they will probably have to use it for the rest of their sexual life will not have this problem.


Chances of Side Effects

Recent medical studies have shown the amount of people affected by side effects when taking Viagra. In this particular test roughly 1500 people took medication. Half took Viagra and half took a placebo. Here are the results:

People that took Viagra

Headaches 15%
Flushing 10%
Indigestion 7%
Blocked Nose 4%
UTI (Urinary Tract Infection) 4%
Abnormal Vision (colour twinge) 4%
Diarrhoea 3%
Dizziness 2%
Rashes 2%

When the medication was increased to 100mg then indigestion and abnormal vision both rose to 17% and 11% respectively.

As Viagra is the most common form of treatment of Erectile Dysfunction, you can assume that this is because it does not come attached with the potential for many side effects, and when you look at the list above you can see why it is so popular.
