What are the side effects of Viagra?

Posted in Personal Health 26 Mar, 2012

Viagra sildenafil was originally developed as a potential treatment for high blood pressure, but the pharmaceutical manufacturers Pzifer Inc. quickly discovered that the little blue pill had a lot more to offer. Once they realised it could effectively assist men manage impotence, it almost instantly become one of the most sought after medications in the world. Since then it’s helped millions of men all around the globe.

In response several competing companies quickly started developing similar medications, known now collectively as PDE-5 inhibitors, which like Viagra work within the body by stopping the function of that particular chemical. This is because while an erection requires external stimulation or arousal, the entire process of sexual response is purely chemistry. When men become sexually stimulated, the body uses something called cyclic GMP, or cGMP for short, to relax the muscle lining in the penis to allow more blood to flow inside of the member. This is what causes an erection.

Once no longer required, the PDE-5 is released and breaks down the cGMP which in turn causes the penis returns to a flaccid state. By disrupting this last part of the interaction, Viagra promotes the achieving and maintaining of erections - allowing men to enjoy satisfying intercourse in the event that there is some kind of disruption to this natural process.

While this function has made Viagra highly successful in treating impotence, like all prescription medications it can cause certain side effects.

Viagra side effects are generally quite mild if men experience them at all, but there are some reactions that can be more serious and even life-threatening. Before using any form of PDE-5 inhibitor, you should always make sure you understand each potential side effect and take the appropriate care to avoid them. If required, for severe reactions, you will need to consult your doctor or a medical professional immediately.

Mild Viagra Side Effects

  • Headache
  • Facial flushing
  • Indigestion
  • Upset stomach

These side effects of Viagra are the most commonly reported by men using the prescription treatment. Invariably they disappear relatively quickly, as the body adjusts to the medication but if they don’t it’s usually best to speak with your doctor. It could be something as simple as decreasing the dosage or possibly changing treatments.

Severe Viagra Side Effects

  • Changes in vision relating to colour
  • Light sensitivity
  • Blurred vision

These Viagra side effects are far rarer, but can be very serious. It’s advised that if you experience them at all, you discontinue using the medication and speak to your doctor immediately. The active ingredient is most likely interacting negatively in some way, but further investigation would be required to pinpoint exactly what is wrong.

Priapism

Priapism is considered the most dangerous side effect of PDE-5 inhibitors like Viagra. It’s where an erection will occur for more than 4 hours and if untreated can lead to permanent tissue damage. While very rare, it’s important that priapism is treated as a medical emergency and assistance would need to be found as quickly as possible.

Most of the side effects can be avoided simply by only taking Viagra as prescribed, ensuring you follow the instructions correctly and never take more than one tablet per 24 period. If you are concerned about any reactions you may experience when you take the impotence treatment, it’s always advised you consult your doctor or a medical practitioner for assistance.
