How Does Vilitra 20 mg Work
Cyclic guanosine monophosphate (cGMP) plays a crucial role in achieving an erection because it increases the vasodilation of the penile muscles, increasing blood flow. However, PDE-5 is an enzyme that is known to break down cGMP and cause a weak erection. Vardenafil (the active ingredient of Vilitra) stops the activity of the PDE-5 enzyme by mimicking cGMP. It is structurally so similar to cGMP that the PDE-5 enzyme binds to Vardenafil instead of cGMP. An increase in cGMP concentration in the blood will increase the blood circulation in the penis and help you get/ retain a firm erection during sex.
However, it is important to know that cGMP is activated only when NO (nitric oxide) is released in the corpus cavernosum- the erectile tissue in the penis. And NO is released only as a response to sufficient sexual stimulation. Therefore, Vilitra 20 mg will not work in the absence of sexual stimulation.
Uses of Vilitra 20 mg
Vilitra 20mg is generally prescribed for the treatment of the early stage of erectile dysfunction. It helps you gain and maintain an erection during copulation.
If you plan on taking it occasionally, as per your need- taking a pill half an hour to an hour before having sex is recommended. If you are taking it on your doctor’s advice, take the medicine as per their instructions (usually it’s 1 pill/ day). Don’t take more than the recommended dosage that is, one tablet a day, unless stated otherwise by your physician.
You should avoid taking the pill more than four hours prior to having sex because its potency starts reducing after that. Also, you can have it with or without food but the latter is better as Vilitra works faster without food.
You can rule out this option if you take it on a need basis. However, for those who are to take it daily, it is possible to have missed a dose. In such a condition, you should take the missed dose as soon as you remember it. But if you’re so late that the time for your next dose is due soon, you should skip the missed dose and only take the next one. Never take 2 pills within the span of 24 hours without consulting your physician.
Research has shown the highest tolerable vardenafil dose to be about 80 mg. But it is strongly recommended that you refrain from overdosing on Vilitra 20 mg. Side effects like nausea, dizziness, and myalgia, which are usually rare and of low intensity may get more intense because of an overdose. It may also cause severe back pain. So, you must contact your doctor if you have somehow taken more than the usual dose.

Let your physician know about all the medications you regularly or sometimes take. Some medicines (like those listed below) might negatively interact with Vilitra 20mg.

Interaction With Alcohol
Although taking a little alcohol while under the effect of Vilitra will not affect you, consuming more alcohol can make you dizzy. This is because alcohol will enhance the blood pressure-lowering effect of the drug. So, do not take much alcohol with it.
Interaction with grapefruit juice
The CYP3A4 enzyme, which is present in grapes, degrades vardenafil in the liver. It will slow down the action of Vilitra 20 mg, so you should avoid grape juice.
