How long does Viagra last?

The amount of time that Viagra will last depends on many factors. Dosage, age, and overall health are just some of the factors that can impact how well Viagra works and lasts for someone.

Viagra 100mg

A smaller dosage of Viagra (recommended for older adults) means that the drug won’t last as long.

The average dose of Viagra is 25-100 mg, taken 30 to 60 minutes, or up to four hours before sexual activity. For adults over the age of 65, the recommended dose is 25 mg. Many older adults have slower metabolisms, which means that a lower dose may last longer for them in comparison to a younger person taking a small dose.

Take Viagra before sexual activity, as it takes time for Viagra to absorb into the bloodstream. It’s unlikely that Viagra will help you last longer during sexual intercourse. However, some men—depending on their metabolism—may experience multiple erections while Viagra is in their system. Once it starts working, Viagra typically lasts for up to four or five hours. If you do experience an erection that lasts longer than this (priapism) or is painful, it may be time to seek medical advice.

Viagra won’t necessarily help you recover faster after orgasm. Recovery time (called the refractory period) varies for each individual. Consuming alcohol while taking Viagra can make the medication less effective by decreasing blood flow to the penis.

For people with certain medical conditions, Viagra might not last as long. Feelings of anxiety, depression, or nervousness often cause Viagra not to last as long or be as effective. Having a heart problem, heart disease, diabetes, or other nervous system problems can also cause Viagra not to last as long.

Certain medications may interact negatively with Viagra and interfere with its effectiveness. Drugs that lower blood pressure can interact with Viagra to cause dangerously low blood pressure. Don’t take Viagra with any medication that contains nitrates, which includes street drugs called “poppers” like amyl nitrate and butyl nitrate. Antifungal and antiviral medications may increase the amount of Viagra in the bloodstream, which can lead to toxicity. Talking with your healthcare provider is the best way to determine if Viagra will cause any drug interactions.
