How does Viagra work?

Viagra  works by relaxing muscles in blood vessel walls to help increase blood flow to the penis, making it easier to get and maintain an erection. Viagra is only effective if there is sexual stimulation, such as that occurring during sexual intercourse. When stimulation first happens, Viagra helps increase blood flow to the penis and then works to help maintain an erection.

According to the Boston University School of Sexual Medicine, erectile dysfunction affects up to 52% of men between the ages of 40-70, many of whom turn to erectile dysfunction medications to help with their symptoms. Viagra is a type of erectile dysfunction drug called a phosphodiesterase 5 inhibitor. PDE5 inhibitors keep a particular enzyme called phosphodiesterase type-5 (PDE5) from acting too quickly. If PDE5 acts slower, then a substance that’s responsible for relaxing muscles and widening blood vessels can do its job.

Viagra will not be as effective for people with certain conditions. You may not get the full benefits of Viagra if you are sick, fatigued, or intoxicated. Alcohol can worsen the side effects of viagra and potentially make erectile dysfunction worse.

You should take Viagra on an empty stomach about one hour before sex. It starts working within 30 to 60 minutes, but an erection requires sexual stimulation.

“Some patients experience the effects of Viagra within 20 to 30 minutes after taking the medication,” says Amber Williams, Pharm.D., a compounding pharmacist at Family Pharmacy in Sarasota. “However, if the dose is taken with a high-fat meal, the peak response may be delayed for up to 60 minutes.

In most patients, the effects of Viagra will last for up to two hours. A duration of two hours or less indicates that an appropriate dose was taken. If the duration is greater than four hours, medical attention should be sought out immediately to avoid damaging effects on the tissues.”

VIAGRA works for men with ED by increasing blood flow to the penis so you can get and keep an erection hard enough for sex.* VIAGRA only works when you are sexually stimulated. It has been proven to help guys with all degrees of ED. VIAGRA usually starts to work within 30-60 minutes. And you only take it when you need it.
