How Does Viagra Work?

Viagra is arguably one of the most well-known brand names for medications for the treatment of erectile dysfunction (ED). But how does Viagra work exactly? In this article, we will explore the answers to that question, discussing what Viagra is, how it works, and the potential side effects of this medication.

What Is Viagra?

Viagra is a prescription medication that contains sildenafil citrate – a chemical compound designed to treat men with erectile dysfunction (ED). This drug was initially created as a treatment for angina, a chest pain associated with heart disease, but it was quickly discovered that it could also be used as an effective treatment for ED.

Rarely, Viagra is also prescribed off-label as a treatment for pulmonary arterial hypertension (PAH).

How Does Viagra Work?

Viagra works by increasing the levels of a chemical called cyclic guanosine monophosphate (cGMP). This chemical helps to widen the walls of the blood vessels, allowing the penis to become engorged with blood. Without the blood being able to flow into the penis, it is impossible to achieve an erection.

With the help of Viagra, the man will be able to achieve a more sustainable erection. It is important to note that Viagra itself does not induce an erection, but rather makes it easier for the man to achieve.

When Should Viagra Be Taken?

Viagra should be taken approximately 1 hour before the planned sexual activity. This is the amount of time it takes for the medication to become effective and allow an erection to be achieved.

It is worth noting that Viagra is only effective when a man is sexually aroused. Without any arousal, the medication will not work.

Potential Side Effects of Viagra

As with all medications, there are potential side effects of Viagra. The most common side effects of Viagra include headaches, flushing, upset stomach, stuffy nose, redness or warmth in the face, neck and chest, and impaired vision.

In rare cases, the side effects of Viagra can be much more severe, such as blurred vision, chest pain, decreased hearing, difficulty breathing, priapism (a prolonged or painful erection), seizures, and a sudden decrease or loss of vision. If you experience these side effects, contact your healthcare provider as soon as possible.

Conclusion

Viagra is a prescription medication used to treat men with ED. It works by increasing the levels of a chemical called cGMP, which allows blood to flow into the penis, enabling an erection. It should be taken approximately 1 hour before planned sexual activity and should always be taken with a doctor’s advice. The most common side effects of Viagra include headaches, flushing, and upset stomach. In rare cases, more serious side effects can occur and it is important to contact a doctor immediately if this happens.
