There have been a lot of talks about the safety of taking Viagra ever since it came out and there are a few reasons why this is true. First of all, it was the first ED drug to get the approval from the FDA. Previously, all the other ED medications have been natural medications that were made from 
natural ingredients that posed absolutely no danger for anyone. However, they also provided with very little beneficial effects, if any.
Still, this has created an opportunity and also a necessity for manufacturers of these natural remedies for ED to start talking about the dangers involved in taking Viagra. They quickly realized that the majority of people will opt for this new medication that has been proven to work and that has shown definite results in alleviating the symptoms of ED. Because of this, they had to find an aspect which would play to their advantage and they found it in the side effects and contraindications for taking Viagra.
This became a huge issue due to the practice of the FDA to make the manufacturers of all drugs to list ALL the possible side effects of their medications and all the potential dangers. This is done for legal reasons and this results in the list of side effects and possible dangers that is a huge one and that was great for the manufacturers of natural products. However, it has to be said that this has also made Viagra look much less safe than it really is. The goal of this article is to talk about the real dangers that are involved with taking Viagra, especially about the possible contraindications for taking it, the cases in which taking Viagra might not be recommended.
One of the most interesting facts about the precautions about taking Viagra is that there are only very few cases in which you should absolutely NOT take Viagra. These cases include taking of nitrate and nitrite drugs, which are usually found in certain heart medications and in certain illegal drugs, popularly known as poppers. The other case is in case the patient is allergic to Sildenafil (the active ingredient in Viagra) or to any other similar PDE5 inhibitors, such as Tadalafil (Cialis) and Vardenafil (Levitra). This is the case with any other medication and it cannot be really considered characteristic of Viagra.
However, there are many more cases in which taking of Viagra should first be discussed with the doctor as there are many conditions that might be affected by taking Viagra or that might affect the way in which your body responds to this medication. You definitely need to talk to your doctor if you are suffering from any of the following potentially dangerous conditions: stomach ulcers, coronary artery disease, retinitis pigmentosa, liver disease, heart disease, kidney disease, bleeding disorders, high or low blood pressure, heart rhythm problems, blood cell disorders and Peyronie’s disease. Also, if you suffered from any of the following cardiovascular events recently, you should also talk to your doctor: heart attacks, congestive heart failure and strokes. Finally, if you have been recommended to abstain from sexual intercourse for any health reason, you should do the same.
You might still be allowed to take Viagra, but your doctor will need to make sure how much of it you can safely take and whether there are reasons for you to undergo any medical testing before you can start taking it.
