Reasons Why Viagra Goes Ineffective

Over-the -counter drugs are not for all even if the problem is common, as there are certain conditions which hinder the proper functioning of the medicine in a person. Thus, before popping a pill we should always consult a trained practitioner. Erectile Dysfunction and Premature Ejaculation are some of the health and sex related problems that can lead to the use of Viagra. This drug was released at the end of the 90s, and it seeks to help people who primarily suffer from impotence. These problems can be caused due to psychological problems like stress and anxiety, as well as other physical reasons including heart disease, diabetes,high blood pressure and other such chronic ailments. Yet there are many instances where this drug does not work. Let us find out more about the causes for the same. 

1. Heart Conditions: To begin with, Viagra cannot be ingested by anyone and everyone. If you are a patient of any kind of cardiovascular diseases and have been prescribed drugs that contain nitrate, then Viagra is not for you. This drug can hinder the work of the medicine and cause some serious side effects, which may make your chronic ailment even more problematic and severe. 
2. Side Effects: Viagra tends to have a lot of side effects for people and does not work efficiently in such cases. One of the most prominent side effects includes prolonged and persistent headache or change in blood pressure which can be serious. Also, the patients may suffer from temporary colour blindness and may not be able to tell colours like yellow and orange apart. 
3. Narrowing or blockades of Blood Vessels: When a man gets an erection, the blood usually flows at a rapid rate into the penis so that the Penis increases in terms of size, thickness and length, with subtle changes in the colour as well. This happens through the blood vessels where the blood flows in from. These are known as in and out vessels. If these vessels happen to be too narrow or block for a patient, then the erection will not be able manifest. This is also one of the primary reasons why Viagra does not work for some people. 
4. Arteries: One of the other reasons why Viagra may not work is the arteries. If the arteries are too narrow or blocked then they will not be able to support the flow of blood for the erection to happen. This can cause problems in achieving and maintaining an erection, in which case Viagra cannot work properly. 
5. Drug Intolerance: The primary work of Viagra is to help the blood vessels in relaxing. Yet, it is possible that the patient may develop some amount of intolerance towards the drug that will end up restricting its action.
