How long does Viagra work?

 Viagra usually starts working 30 to 60 minutes after taking the drug. But Viagra itself will not give you an erection. Instead, you will have sexual arousal for the drug to work.

Viagra works in your body for up to 5 hours. This means that if you are aroused, you should have an erection within 4 hours of taking Viagra. So its preferable to 비아그라 

Although Viagra works for several hours in your body, your erection should not last that long. In fact, rarely can Viagra cause priapism. With this condition, you have a long and sometimes painful erection.

Priapism is an emergency medical procedure that requires immediate treatment. If left untreated, this can damage the tissues of your penis and cause irreversible erectile dysfunction (ED).

If you have an erection that lasts longer than 4 hours, go to the nearest emergency room or call 911.

What can I do to make Viagra work faster?

Viagra can work faster if you take it on an empty stomach. However, if Viagra is taken with food, especially fatty foods, the onset of labor will take longer. In this case, it may even be less effective for you.

How long will Viagra stay in my system?

After taking a dose of Viagra, the level of the drug in your body will gradually decrease over several hours. After about 4 hours you will have low medication in your body. (And at this point, the drug will no longer work.) But it can take up to 24 hours for Viagra to be completely removed from your body.

How Viagra works

Viagra is approved for the treatment of erectile dysfunction in men. With ED, you have trouble getting and maintaining an erection that is strong enough to cause you to have sex.

What causes an erection?

When you are sexually aroused, either through sexual thoughts or touch, your brain sends messages to the penis. These messages cause certain chemicals in your penis.

One of these chemicals, called cyclic GMP, soothes and dilates certain blood vessels in the penis. Cyclic GMP also relaxes the muscles around the erectile tissue of your penis called the cavernous body. These actions give blood to the cavernous body, causing your penis to harden and erect.

What happens to ED?

ED can occur if you have certain problems that affect your body’s ability to get an erection. This condition can lead to problems sending messages from the brain. ED can also cause circulatory problems in the penis.

What does Viagra do for ED?

Viagra works to treat ED and help you maintain an erection. The drug does this by improving blood flow to the penis when you are sexually aroused.

Viagra is a type of drug called a phosphodiesterase type 5 (PDE5) inhibitor. It acts by inhibiting the action of an enzyme called PDE5. (An enzyme is a protein that helps chemical reactions occur in your body.)

Normally, an erection goes when PDE5 destroys the cyclic GMP of your penis. But Viagra blocks the action of PDE5, so it allows cyclic GMP to continue to work longer than usual. This action improves blood circulation to the penis and helps you maintain and maintain an erection.
