Viagra Contraindications

Viagra and poppers
Opposing to what many people think, there is nothing miraculous about Viagra. This is just a medication that wisely makes our body act that way it should. Viagra acts as a vasodilator and the same action is performed by nitrates. This can bring to fatal consequences. Sildenafil may induce hypotensive effects if the person just inhales amyl nitrate, nitrite called "poppers". Both medications bring to the relaxation of the muscles. The diameter of blood vessels become too wide and the blood pressure decreases. Therefore, these substances are contraindicated. Viagra and poppers act in the same way deteriorating the condition of the patient.
The hazard of lethal outcome
Why are poppers taken by the patients? They serve to dilate the blood vessels. As a result, the blood pressure lowers suddenly and this can be dangerous for health and even become lethal for some patients. The medications that cause such problem are ritonavir [Norvir], indinavir [Crixivan], nelfinavir [Viracept], saquinavir [Invirase].
Why are the dietary sources harmless?
But what about food? Can some products create health problems? As for the dietary sources, it all is different here. Nitrates and nitrites will hardly interact with Sildenafil because they do not contribute to nitrous oxide in humans. For this reason, there is no interaction and nitrous oxide in dietary products does not harm the patients. The same is referred to anesthetic agent nitrous oxide. Its biotransformation is not noticeable and passes without changes. Besides, It is destroyed very fast - within several minutes.
Make intervals to be safe!
Co-administration of medicines that are contraindicated to each other can be prevented if you make intervals between their intakes. Administration of nitrates should be considered only 24 hours after Sildenafil. There is a list of medications you should exclude when Viagra is prescribed to you. Your doctor should know about all medicines that you take to avoid the problems of this type.
Precaution measures
All patients are warned by their doctors about the potential problems that can arise in case they take forbidden medications together. FDA even issued the warning concerning this point.
Viagra should not be combined with other PDE5 inhibitors as well.
It is often hard to distinguish, which medications contain forbidden substances, therefore you should not take drugs without doctor's permission.
