This action improves blood flow to your penis and helps you get and keep an erection.

Viagra works by blocking the action of a certain enzyme in your body. Since Viagra has been released onto the market, there have been a few reports of bleeding in people who have taken the drug. However, there’s no evidence that Viagra caused these bleeding problems.
The appropriate dose depends on factors like age, kidney or liver problems, and other medications being taken. While generally considered safe, Viagra can cause side effects, including headaches and low blood pressure. It can also interact negatively with other medications like nitrates. Viagra is a brand-name oral tablet prescribed for erectile dysfunction (ED). You’ll find key information about Viagra below.
Drug class: phosphodiesterase type 5 (PDE5) inhibitor In several clinical studies, Viagra was effective in treating erectile dysfunction (ED). In these studies, males who used the drug had an improved ability to have and keep erections during sexual activity. To learn more about Viagra’s effectiveness, see the “Viagra uses” section. Use of the term “male” in this article refers to sex assigned at birth. Viagra typically starts to work between 30 and 60 minutes after you take a dose of the drug. It’s not known if Viagra is safe for use in people with a bleeding problem. If you have any bleeding problems, talk with your doctor about whether Viagra is safe for you. After taking a dose of Viagra, the drug’s level in your body will gradually decrease over a period of a few hours. You’ll have low levels of the drug in your body after about 4 hours. (And at this point, the drug won’t be working any longer.) But it can actually take about 24 hours for Viagra to be completely removed from your body. If you have other questions about how long Viagra works, talk with your doctor.
But Viagra itself doesn’t give you an erection. You’ll need to be sexually aroused in order for the drug to work. Viagra keeps working in your body for up to 5 hours. This means that if you’re aroused, you should still be able to get an erection up to 4 hours after taking a dose of Viagra. Even though Viagra keeps working in your body for several hours, your erection shouldn’t last this long.
In fact, in rare cases, Viagra can cause priapism (a long-lasting and sometimes painful erection). Priapism is a medical emergency that needs to be treated right away. If it’s not treated, the condition can damage the tissues in your penis and cause irreversible erectile dysfunction. If you have an erection that lasts longer than 4 hours, go to the nearest emergency room or call 911. Viagra may work faster if you take it on an empty stomach. Viagra can cause mild or serious side effects. The following lists contain some of the key side effects that may occur while taking Viagra. These lists don’t include all possible side effects.
| Point | Explanation | Additional Advice |
|---|---|---|
| Take on an empty stomach | Food, especially high-fat meals, delays absorption | Preferably 1 hour before planned activity |
| Do not exceed prescribed dose | Risk of adverse effects | Follow doctor’s guidance |
| Engage in sexual activity only if adequately stimulated | Effectiveness depends on arousal | Not a treatment for low libido or without stimulation |

If Viagra is taken with food, especially with a high fat meal, it will take longer to start working. And in this case, it could even be less effective for you. Viagra is approved to treat erectile dysfunction (ED) in males. With ED, you have trouble getting and keeping an erection that’s firm enough to allow you to have sex. When you’re sexually aroused, your brain sends messages to your penis.
These messages cause certain chemicals to be released in your penis. One of these chemicals, called cyclic GMP, relaxes and widens certain blood vessels in your penis. Cyclic GMP also relaxes the muscles around the erectile tissue in your penis that’s called the corpus cavernosum. These actions allow blood to flow into the corpus cavernosum, which causes your penis to get hard and become erect. ED can occur if you have certain problems that affect your body’s ability to have an erection. But if they become more severe or don’t go away, talk with your doctor or pharmacist. * This is a partial list of mild side effects from Viagra.
The condition can result from problems with messages being sent from your brain. ED can also result from problems with blood flow into your penis. Viagra works to treat ED by helping you get and maintain an erection. The drug does this by improving blood flow into your penis when you’re sexually aroused. Viagra is a type of drug called a phosphodiesterase type 5 (PDE5) inhibitor. To learn about other mild side effects, talk with your doctor or pharmacist, or view the drug’s prescribing information.
