What is Viagra?

Viagra is a popular treatment for erectile dysfunction (ED), a common condition experienced by men. It is produced by the pharmaceutical company Pfizer.

It is clinically proven Trusted source PubMed Government Source Database of Biomedical Research Go to source to help achieve better erections and improve the lives of men worldwide. It works in as little as 30 minutes, and the effects last up to 4 hours.

How does Viagra work?

Viagra treats erectile dysfunction by increasing blood flow to the penis.

An erection occurs when sexual arousal stimulates the brain. The brain then sends messages to the penis via the nerves. These messages tell the muscles in the penile wall to relax, allowing blood to flow in and fill the open spaces.

The blood enters faster than it can leave through the veins. The veins get compressed, trapping the blood in the penis to achieve and maintain an erection.

Viagra contains the active ingredient Sildenafil citrate, this medication is known as a PDE-5 inhibitor. It prevents the breakdown of a chemical that causes the smooth muscle to relax in the penis. This increases the flow of blood into the penis, resulting in longer-lasting erections.

Please note that for this treatment to work, you must first become sexually aroused.

What are the benefits of Viagra?

Aside from treating ED, Sildenafil has been shown to have many other benefits.

This medication is designed for you to take it as you need it, so it doesn’t matter if you forget to take a dose. Missing a dose may affect the quality of your erection.

The length of time this medication takes to work can be affected by factors such as food, alcohol and sexual stimulation.

How long does Viagra last?

Viagra lasts around 4 hours however, this may vary from person to person. If your erection lasts longer than 4 hours there is a risk that this could cause tissue damage to the penis. If this happens, seek immediate medical help.

Who can and cannot take Viagra tablets?

Sildenafil may not be suitable for some people. To make sure it's safe and right for you, speak to your doctor.

Who can take it?

Most adult men (over the age of 18) with erectile dysfunction can take Viagra.

  • severe vision loss or non-arteritic anterior ischemic optic neuropathy (NAION)

What is the difference between branded and generic Viagra?

The generic drug has the same active ingredient, Sildenafil citrate, as the brand-name drug, Viagra, and works just as well. The main difference between the two is the price; the generic version is usually much cheaper.

The same goes for Viagra Connect, which is a brand of Viagra that you can purchase without a doctor’s prescription.

Viagra Connect vs Viagra

Viagra Connect is only available in 50 mg doses, whereas Viagra is available in 25 mg, 50 mg, and 100 mg doses. It's also more expensive, most likely because it's more 'accessible' and convenient to buy.

How do I store this medication?

Store the tablets at room temperature (below 30° C). Keep these tablets in their original package to protect them from moisture and excess heat. Ensure this medicine is kept out of the reach of children.

Do not use Viagra after the expiry date stated on the carton.

Do not throw this medicine away in your household waste or flush it down the toilet. You can take this medicine to your nearest pharmacy to safely dispose of it.

What lifestyle changes should I make when taking Viagra?

Although Viagra is an effective pill, there are several factors that can influence how quickly and effectively it works. Here are some tips that can help ensure it works well for you.

Avoid heavy meals

Viagra is absorbed quicker on an empty stomach compared to when taken after a meal. Studies Trusted source DailyMed Government Source US National Library of Medicine Drug Labels Go to source show that if you take Viagra after a heavy, high-fat meal, it can delay your body's absorption of Viagra by up to an hour. This means that it may take longer to achieve an erection.

Avoid alcohol and drugs

While it’s safe to drink alcohol in moderation when taking Viagra, drinking may make it more difficult to get an erection.

Alcohol can affect many different systems in the body, including those involved in producing an erection. Excessive drinking may also increase your risk of developing side effects such as headaches, nausea and dizziness.

Don’t smoke

Tobacco smoke contains many chemicals and toxins that can damage the lining of the blood vessels. Smoking can impair circulation to all areas of the body, including the penis.
Studies Trusted source National Center for Biotechnology Information (NCBI) Government Source Biomedical Research and Literature Go to source have shown that smoking increases the risk of developing ED. The best thing you can do to improve ED is to stop smoking.

I recommend that patients take Viagra on an empty stomach or with a light meal to achieve the best results. Patients should avoid smoking, alcohol and drugs when using Viagra as these could dampen its effects.
