How does Viagra work?
Viagra is a PDE5 inhibitor, meaning it works by allowing blood vessels to expand and relax. This increases blood flow to the penis when a man is aroused, which improves sexual performance for men with erectile dysfunction (ED). Sildenafil and Viagra work in exactly the same way, because the active ingredient is identical.
How long does it take for Viagra to work?
Viagra usually starts to work within 30-60 minutes. Maximum erection potential is usually after 1 hour. Learn more on our blog.

What causes erectile dysfunction?
There are many causes of ED, generally split into psychological or organic/psychological causes (such as medications, hormonal, neurovascular, anatomical factors). In many patients it can be a combination of factors, and so we advise having a checkup by a doctor. We give comprehensive guidance on what you should have checked with our prescription message.
When and how to start treatment/should I start treatment?
Approximately 40% of men are affected by ED at age 40 and nearly 70% of men at age 70. So it's very common. However, the statistics show most men don’t seek treatment for it.
So if your having erectile dysfunction, don’t ignore it. There is plenty that can be done to help. You should also have a health check and see what might be causing it.
If you decide to treat the problem, an oral medication like Viagra is the most popular and common way to start. Many men find it really improves their sexual confidence to have access to it in their time of need. So over time their erections improve, and they can stop needing medication.
For others, it’s just there whenever they need it and that's ok. Provided you take it as prescribed, it's not doing you any harm.
We are experts at prescribing for erectile dysfunction online. We’ll ensure it's safe for you, and give all the advice and guidance you need. We’re here for you.
How effective is it?
It’s suggested that 85% of men who take Viagra achieve erections strong enough for sex.
Viagra was the first treatment to be clinically approved to treat erectile dysfunction. Since then a number of similar medications have come onto the market, such as Cialis, Levitra, and Spedra. In a review of 82 trials covering over 47,000 patients, Viagra 50mg was found to be the most effective of all other comparable medications. Hence why it's our treatment of choice.
How long does Viagra work for?
Viagra starts to work within 30-60 mins and maximum erection potential happens after the one hour mark. It should last around four hours, in some cases longer.
Are there any side effects?
If present, side effects from taking Viagra are usually mild and temporary.
The most common side effects of Viagra are: Headache, flushing, indigestion, nasal congestion, dizziness, nausea, hot flushes, vision changes (such as having a blue colour tinge, or blurred vision).
Please read the patient information leaflet carefully for a full list of side effects and advice.
Cautions / how do I get the most out of the treatment?
Do not take more than one dose of Viagra in a 24-hour period.
Viagra will only work if you are sexually aroused, so ensure you still engage in foreplay.
Do not drink large amounts of alcohol before you plan to take Viagra. Drinking too much alcohol can reduce your ability to get an erection and this may prevent you from getting the maximum benefit from the tablets.
It is recommended that you do not drink grapefruit juice with Viagra. This is because grapefruit juice can increase the amount of Viagra in your bloodstream and this makes side-effects more likely.
If you feel the tablets are too strong for you, discuss this with the clinician as your dose may need to be reduced. Alternatively, if you do not get an erection after taking Viagra, or if it does not last long enough for you to have sex, you should discuss this with your clinician - do not take more tablets than you have been told to.
You should not take Viagra if you are using any other products or taking any other medicines that treat erectile dysfunction.
If you’ve had an erection lasting longer than 4 hours, it’s time to seek urgent help. Go to your local A&E immediately.
