Viagra: Understanding the reason behind its side effects

There are very very few drugs that do not provide side effects. Instead most drugs result in these unwanted effects. Viagra is no exception. A common misconception by people is that if a drug has possible side effects then it should not be used.

This is not true. There are many positive benefits to using drugs which might contain side effects. Consider the case of an aspirin, taking an aspirin is an excellent way to cure a pain which you might be experiencing, but aspirins also might cause side effects such as a eroding of the stomach lining and a thinning of the blood.

These reflect themselves in stomach pain and possible ulcers. So whilst these are the possible side effects of an aspirin they are still daily used by millions of people all over the world.

Side effects are measured by risk values. Drugs that provide side effect with little long term risk of injury are generally used by the public. However if a drug contains severe possibilities of side effect, i.e. , if taking the drug will both cure your symptoms and leave you paralyzed then it is understandable if you  choose to avoid the drug.

In giving the approval of use of a drug to the public, health regulatory bodies such as the FDA take into account the positive as well as the negative side effects of the drugs. Any drug that is found to possess to great a side effect is not allowed into the public use.

That said, the following are some of the common side effects which taking Viagra pills might cause and some of the reasons behind them

Troubled Vision: Sometimes people who take Viagra pills begin to see the world differently. Literally. Their color vision is altered and they begin to notice differences in the way they perceive blue and green colors.

This side effect occurs the effect of Viagra does not only block the PDE5 enzyme—which is key to relaxing the penile muscles, it also has an effect on PDE6. PDE 6 is used the cone cells in the retina.

As a result of this, taking Viagra can cause an alteration in color vision. However, because Viagra stays in the body for about 4 hours, this effect will hardly last a day before leaving.

Other side effects which are caused by Viagra include aches that are caused as a result of the opening arteries. Viagra tablets cause the arteries in the penile areas to open up more.

However, they also affect other arteries such as those found in the pulmonary area as well as those found in the brain. Opening the arteries found in the brain can cause increased pressure and this is what reflects as headaches,  depending on the person’s condition, this arterial expansion can also result in possible cardiac conditions; this is why patients are urged to seek medical advice/opinion before looking buying Viagra tablets.

This is also the reason why Viagra pills are sold with a prescription in many countries including the United States. Finally, in extremely rare cases, some men might develop an erection that lasts for hours. This is not as much fun as it might sound and is in fact quite painful.

When this occurs the opinions of a doctor should be immediately sought.

Viagra tablets can be bought at online pharmacies. However it is important that you only buy real Viagra tablets. Avoid counterfeit Viagra.
