Viagra is a medication used to treat erectile dysfunction (ED) in men. It is a brand name for the drug sildenafil citrate and was first approved by the US Food and Drug Administration (FDA) in 1998. Since then, Viagra has become one of the most widely recognized medications in the world, with millions of men using it to treat their ED.
How Does It Work?
Viagra works by increasing blood flow to the penis, which helps to achieve and maintain an erection during sexual stimulation. It is a phosphodiesterase type 5 (PDE5) inhibitor, which means it blocks an enzyme that breaks down cGMP, a molecule that regulates blood flow in the penis. When cGMP levels increase, blood vessels in the penis dilate, allowing more blood to flow into the penis, resulting in an erection.
When Should You Take It?
Viagra should be taken 30 minutes to an hour before sexual activity. It is important to note that sexual stimulation is still needed to achieve an erection. Viagra should not be taken more than once a day, and it is not recommended to take it with high-fat meals as it may delay its effectiveness.
Side Effects
Like all medications, Viagra can cause side effects. The most common side effects include headaches, facial flushing, indigestion, and nasal congestion. These side effects are usually mild and go away within a few hours. In rare cases, Viagra can cause more serious side effects such as sudden vision loss or hearing loss. If you experience any of these side effects, seek medical attention immediately.
Who Should Not Take It?
Viagra should not be taken by men who are taking medications containing nitrates, such as nitroglycerin, as this can lead to a sudden drop in blood pressure. It is also not recommended for men who have severe liver or kidney disease, low blood pressure, or have had a recent heart attack or stroke. It is important to discuss any medical conditions or medications you are taking with your healthcare provider before taking Viagra.
Is It Safe?
Viagra is generally considered safe when taken as directed by a healthcare provider. However, like all medications, there are risks and potential side effects. It is important to follow the instructions provided by your healthcare provider and report any side effects or concerns you may have.
Alternatives to Viagra
There are several other medications available to treat ED, including Cialis and Levitra. These medications work in a similar way to Viagra but may have different side effects or duration of effectiveness. It is important to discuss the options with a healthcare provider to determine which medication may be the best choice for you.
