Designed to be taken as needed shortly before sexual activity, Viagra can take 30 minutes to an hour to take effect. It can last in your system for up to 4-5 hours and help you become erect anytime during that window. The most common dose is 50 milligrams (mg), and it should not be taken with food. Instead, Viagra is most effective when taken on an empty stomach.

For most men, Viagra is a safe and effective treatment option for ED. However, it can cause side effects, including dizziness, nausea, rash, pain in the arms or legs, and abnormal vision.

Causes of Erectile Dysfunction
There are several potential causes of ED, including underlying health issues such as heart disease or diabetes. The causes of ED are often categorized into two types: organic (physical) and psychogenic (mental).

Approximately 80% of ED cases are organic, meaning they’re caused by endocrine or non-endocrine factors. Endocrine-related causes are often connected to low testosterone levels, though more research is required to fully understand how the two intersect. Non-endocrine related causes of ED include medical conditions that affect blood supply, blood flow, and nervous system function.

Studies also suggest that there is often a psychogenic component of ED, even in cases with organic causes. Whether or not psychological conditions contribute to the cause of your ED, the condition can have negative effects on your psychological well-being, including mood, quality of life, and intimate relationships.

If you’re experiencing symptoms of ED, it’s important to talk with your provider to determine the cause and right course of treatment for you.
Treatment for Erectile Dysfunction
There are four FDA-approved medications to treat ED in men: sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Stendra).

All of these are phosphodiesterase-5 (PDE5) inhibitors. They work by enhancing the effects of nitric oxide to relax the penile muscles, expand blood vessels that go into the penis, and improve penile blood flow. This helps improve the ability to get and maintain erections.

However, PDE5 inhibitors like Viagra can interfere with certain medications, including alpha blockers and heart medications that contain nitrates. For this reason, not all men are eligible for ED treatment like Viagra.
