What is Viagra?

Viagra is a safe and effective medicine for the treatment of erectile dysfunction. It is used by men who have
trouble achieving or maintaining their erection. Viagra contains the active ingredient sildenafil and was the first
medicine to be licensed for treating erectile dysfunction. It has been used for over 17 years and has helped to
treat  more than 20 million men around the world. Viagra has been shown to be effective for 88% of men.

How does Viagra work?

The active component in the medication, sildenafil, is a Phosphodiesterase type 5 (PDE-5) inhibitor, which works on the muscles that surround the blood vessels in the groin region. It causes the muscles to relax, allowing the blood vessels within to enlarge and allow more blood to pass through. This extra blood flow to the penis is responsible for helping an erection to occur.

There are many processes that normally occur in a man’s body when he is sexually aroused that eventually lead to an increase in blood flow to the penis and a resulting erection for sexual activity. As it is the final step in the process of having an erection, it successfully helps the vast majority of men suffering from ED, no matter what the original cause is.

When should you take Viagra?

The majority of medications used to treatment ED are not used every day, but rather when they are needed. For this reason, you should take care to time the dose well to ensure it is working with optimal results when you need it.

It takes approximately 30 minutes to become effective enough to allow sexual activity and after about 4 hours, the optimal effect begins to wear off. Therefore, you should be prepared and aim to take the pill about 1 hour before sexual activity. You will then be ready when you need to be, but the effect should last long enough to allow you to fulfill your sexual needs.

It doesn’t matter if you take this medication with or without food, as it will have approximately the same effect regardless. However, it may take slightly longer to work if you take it with or soon after a heavy meal.

What Dose Of Viagra Should you Take?

Viagra comes in three different doses: 25mg, 50mg and 100mg. These options allow you to find the right dose to help obtain an erection, whilst also decreasing the risk of any possible side effects.

It is best for most men to start with the standard dose of 50mg to understand how it affects their body, and then we can alter the dose if needed. If it has good results and you don’t notice any side effects, continue with the standard dose.

However, if you do notice any unwanted effects after taking this medication, it is recommended that you decrease the dose to 50mg. This is often successful in eliminating side effects, whilst still providing the desired results.

On the other hand, if you find that it isn’t working as well as you would like, you can increase the dose to 100mg. You should try the standard dose on four separate occasions before increasing the dose, to ensure that it is not a one-off occurrence. If you still aren’t satisfied with the results you should see your doctor to discuss other medication options. Increasing the dose more than 100mg is not likely to produce effective results, so discussing different options is the best way forward.

What are the Side Effects of Viagra?

Viagra is generally well tolerated and comes in a variety of dosages so the strength can easily be decreased for men
experiencing bothersome side effects. Some men may experience side effects when taking Viagra, and it is best if you are aware of these before taking the medication so that you can recognise them if they do occur.

  • Headache – the most common adverse effect that can affect up to 10% of users and occurs in varying degrees of severity.
  • Visual Problems – blurred vision, altered colours and associated dizziness.
  • Stomachache – nausea and indigestion.
  • Nasal congestion – blocked or runny nose.
  • Flushing – red flushing of the face and feeling of heat in the upper body.

Fortunately, because this medication has a short duration of action and usually wears off after about 4 hours, the side effects usually cease with the effect. This is comforting to know if you do experience side effects, as they are usually temporary.

For this reason, some men who experience side effects do not find them invasive enough to change the dose. If you do experience uncomfortable side effects, lowering the dose or changing to another medication to treat ED may help.

How long does Viagra Last?

Viagra will stay in the body on average 4 hours after dosing. For some men it may remain as long as 5 hours, or a
few as 3 hours.

How Long Does Viagra Take To Work?

When taken on an empty stomach, Viagra is absorbed relatively rapidly and it will usually work within 30-60 minutes,
although it may take up to 120 minutes in a small percentage of men. Taking Viagra with food will decrease the rate
of absorption and can significantly increase the time taken for Viagra to work.

less effective than hoped, or for whom planned dosing is difficult, there are other PDE5 inhibitors available in
