How long does Viagra work?

If you are thinking about taking Viagra, it is useful to know what you can expect from the “little blue pill”. One question that many people ask themselves is how long it is active in their system. So what is Viagra, how long does Viagra work and what could affect it?

What is Viagra?

Viagra is the most popular treatment for adult men with erectile dysfunction. This is when a man cannot get or keep a hard, erect penis suitable for penetrating sex. Viagra belongs to a class of drugs known as PDE-5 (phosphodiesterase type 5) inhibitors. PDE-5 is basically an enzyme that your body produces and that stops blood flow to your penis – PDE-5 inhibitors prevent this enzyme from being released for a certain amount of time.

Viagra and the other PDE-5 inhibitors can help men with erectile dysfunction (male impotence) by increasing the erectile response when a man is sexually stimulated.

How long does Viagra work?

Viagra is most effective in the first 0-5 hours after taking it – but in many cases the drug can continue to cause an erection for several hours longer. Viagra remains in your body for about 24 hours, although its effects usually wear off after about 12 hours.

Once you have taken Viagra, you can usually expect a hard erection to last up to 33 minutes (on average), or slightly less when you are older.

The effects of Viagra will not begin until you actually feel aroused – you will not get an erection with Viagra unless you feel “aroused”. You won’t have a constant erection either – despite some depictions of the drug in popular culture! Your penis “goes down” when you don’t feel “aroused”, so you don’t need to worry about being embarrassed in public.

When should you take Viagra?

Viagra should be taken one hour before you expect to engage in sexual activity. Although it has been shown to work for some people as early as 12 minutes after taking the drug, the average time to take it is about 30-60 minutes. Think about when you expect to have sex in advance and then take a pill. The good news is that Viagra continues to work for a few hours after you take it, so there is no need to rush.

Some of the factors that affect how long Viagra works include

Dosage – The amount of Viagra you take will affect how long the effect lasts. The smallest dose (25 mg) will not last as long as the largest dose (100 mg). It is important that you consult your doctor before taking a higher dose, as it may not be safe for you.
Age – The older you get, the more your metabolism slows down. This means that Viagra may work longer as you get older.
Medication – Some medications may interact with Viagra and affect the length of time you take it. It’s best to ask your doctor when you think about taking Viagra and inform him or her about the medications you are taking (especially if you have diabetes or high blood pressure).
Food – It is best not to eat too much before taking Viagra. This is because a heavy meal before taking the medicine can prevent it from being broken down.
General health – Diseases such as diabetes and heart disease such as atherosclerosis can affect the effectiveness of Viagra.

Alcohol – Drinking alcohol reduces the blood flow to the penis. Excessive alcohol consumption can affect erections, whether or not you suffer from erectile dysfunction.
Illegal drugs – Illegal drugs, like alcohol, can interfere with the effects of Viagra, so it is best to avoid them. It is also important not to mix Viagra with drugs known as “poppers” as this can have negative side effects.
Mental health – If you feel particularly stressed or anxious, Viagra may not work for you.

How often should Viagra be taken?

It is important to remember that Viagra should only be taken once every 24 hours. This means just one pill, regardless of the dosage. It is also important never to take Viagra together with other erectile dysfunction medications as this can cause physical damage to your penis.

If the prescription prescribed by your family doctor does not seem to work, do not be tempted to “double” the dosage. This can have adverse effects and can do more harm than good. If Viagra does not work for you the first time, talk to your doctor, and he or she may either increase the dose or put you on an alternative treatment.

What dose of Viagra should I take?

Viagra comes in three doses: 25 mg, 50 mg, and 100 mg. The recommended starting dose is a 50 mg tablet. 100 mg is the maximum dosage, but it is important that you are fit and have no health problems if you want to start with such a high dose.

How long does Viagra stay in your system?

Viagra remains in your system for about 24 hours, although the effect of Viagra is less pronounced after about 4-5 hours.

Is there anything I can do to make Viagra work longer?

Yes, of course. As mentioned above, there are a number of lifestyle factors that can slow down or interfere with the effectiveness of Viagra. By changing some of your behavior, you may be able to influence how well Viagra works – and you may not need it at all.

Getting fit – losing weight and getting in shape can help make Viagra more effective so that blood can flow more efficiently through your body. It can also help with problems with your body image that can make you feel uncomfortable in the bedroom.
Drink less alcohol – Alcohol has long been associated with erection problems, so drinking less will almost certainly help to ease erection problems.
Smoking – Smoking is also a common cause of erectile dysfunction as it can damage the blood vessels. If you stop smoking, it may mean that Viagra works better for you – and you may not need it anymore.
Reduce stress – Try to relax before sexual activity – don’t bring the office into the bedroom!
I am not getting the desired effect from Viagra – can I take more than one tablet?
No, you should never take more than the prescribed dose of Viagra. If the effect is not as good as you would like, consult your family doctor.

What are the best alternatives to Viagra?

There are a number of alternative treatments for erectile dysfunction, including

Cialis: Known as the “36-hour pill”, Cialis contains the active ingredient tadalafil and offers a long-lasting solution for erectile dysfunction.
Sildenafil: Sildenafil is essentially the same drug as Viagra without the brand name Viagra and is much cheaper.
Spedra: Spedra is the fastest acting ED medication and should be taken about 15 minutes before sex.
Knowing when to take Viagra and how long it works can be helpful to get the most out of the medicine. By keeping these points in mind, you can get the Viagra effect that you and your partner want.
