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. 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. 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.
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.

"Viagra patent expires in June, says Brazilian court". Archived from the original on 17 April 2012. 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. It works by inhibiting (blocking) the action of an enzyme called PDE5. (An enzyme is a protein that helps chemical reactions to happen inside your body.) Usually, an erection goes away when PDE5 breaks down the cyclic GMP in your penis. But Viagra blocks the action of PDE5, so it allows cyclic GMP to keep working for a longer period of time than usual. This action improves blood flow to your penis and helps you get and keep an erection. No, Viagra doesn’t directly increase your sex drive. And it doesn’t make you sexually aroused. However, some people find that if Viagra works to treat their erectile problem, it also increases their sexual confidence. And this may lead to an increased sex drive. Viagra may not work for everyone, and it may not work every time you take it. If you’re sexually aroused, Viagra should work to help you get or keep an erection within 30 minutes to 2 hours. But if you don’t get an erection within 4 hours after taking a dose, Viagra didn’t work for you this time. If the drug doesn’t work for you, you shouldn’t take another dose until at least 24 hours later. And talk with your doctor if you feel Viagra isn’t helping to treat your ED. They may recommend that you try a different medication for your ED.

It’s important to remember that Viagra only works if you’re already sexually aroused. Arousal may involve having sexual thoughts, looking at sexual images, masturbating, or engaging in foreplay. But if you feel anxious, nervous, depressed, or stressed, your body may not respond well to sexual stimulation. If this is the case, try to relax, make yourself comfortable, and take your time. In addition, if you drink alcohol, it’s best to avoid drinking a lot of it.
