Viagra may also be used off-label for other conditions. ED can be caused by several different factors. These include psychological or emotional problems, such as:. Viagra increases blood flow to your penis, which helps you have and maintain an erection. These success rates varied depending on the cause of their ED and the dosage of Viagra being used.
Some studies looked at the effect of different doses of Viagra. These studies, which involved 1, men, lasted up to 6 months. Improved erections were reported in:. For example, one study specifically looked at men with ED that was related to complications of diabetes.

One review of studies showed that current research has conflicting results on how Viagra affects women. For example, in women with female sexual arousal disorder , the review showed the following findings:. In men, Viagra improves blood flow to their penis by blocking the action of a chemical called PDE5.
This chemical is also found in the vagina and the clitoris of women. So in theory, if a woman takes Viagra, it could increase blood flow to her genitals. This could explain why Viagra has less of a physical effect in women than it does in men. And keep in mind that sexual problems in women often have a lot to do with reduced sexual desire and arousal. Viagra is unlikely to address these issues. Below, we describe the condition Addyi is approved to treat and how the drug works. Addyi contains the active drug flibanserin.
The condition can have various physical or psychological causes. Instead, Addyi affects the activity of certain neurotransmitters that are involved in sexual desire and arousal.

For some women with HDSS, Addyi can improve sexual desire and increase the number of sexually satisfying events.
For example, in clinical studies , treatment with Addyi was compared with that of a placebo no active drug. When you get Viagra from the pharmacy, the pharmacist will add an expiration date to the label on the bottle. This date is typically 1 year from the date they dispensed the medication.
The expiration date helps guarantee that the medication is effective during this time. If you have unused medication that has gone past the expiration date, talk to your pharmacist about whether you might still be able to use it.

Before taking Viagra, talk with your doctor about your health history. Viagra may not be right for you if you have certain medical conditions or other factors affecting your health. These include:. Your insurance plan may require you to get prior authorization before approving coverage for Viagra. This means that your doctor and insurance company will need to communicate about your prescription before the insurance company will cover the drug.

Viagra enhances the action of cyclic GMP, which is released in the penis in response to sexual stimulation. Cyclic GMP dilates smooth muscle in the penile tissue. It also increases blood to flow into the corpus cavernosum, causing an erection. Viagra blocks PDE5 from breaking down cyclic GMP, thereby improving the ability to achieve and maintain an erection in response to sexual stimulation.
When taken on an empty stomach, the time to reach peak plasma concentration Tmax is approximately 30 to minutes. The median Tmax is 60 minutes. Taking Viagra with a high-fat meal delays Tmax by about 60 minutes. Sildenafil is primarily metabolized by hepatic CYP3A4, to a metabolite with similar activity to sildenafil. Sildenafil and its active metabolite have a terminal half-life of approximately 4 hours.
Reduced clearance of sildenafil is seen in people ages 65 years and over, and in those with hepatic impairment or severe renal impairment. Viagra is contraindicated in people with a known allergy to sildenafil, or any of the inactive ingredients in Viagra.

Dr Capogrosso continued "We need to be clear about what these figures mean. They do not indicate any change in the prevalence of these conditions, what they show is why men came to the clinic. In other words, it shows what they are concerned about. The changes probably also reflect the availability of treatments; as treatments for sexual conditions have become available over the last few years, men are less likely to suffer in silence".
