How long does Viagra take to work?

If you have questions about how quickly Viagra will work for you, talk with your doctor or pharmacist.

What should you do if Viagra doesn’t seem to work?

If Viagra doesn’t seem to work for you, talk with your doctor. They may recommend that you take a higher dose of the drug to see if that helps the drug work for you.

In other cases, your doctor may recommend a different medication altogether.

Let your doctor know if you have concerns about Viagra not working.

Can you make Viagra work faster?

In most cases, Viagra works within 1 hour after you take a dose. But if you take your dose on an empty stomach, the drug may work faster. Taking Viagra with a meal that’s high in fat may make the drug work more slowly.

If you’d like to know more about this, ask your doctor or pharmacist.

How long does Viagra last?

Viagra works at its best within a few hours after it’s taken.

Talk with your doctor to learn more about how long you can expect Viagra to work.

How long does Viagra stay in your system? What’s its half-life?

The half-life of Viagra is about 4 hours. This means that 4 hours after you take a dose, your body has cleared half of the dose.

In most cases, it takes about 5 half-lives for your body to completely remove a drug from your system. So this means it may take about 20 hours for Viagra to be completely cleared from your body. But as your body clears the drug, it may not be working any longer.
