How ED treatment works in your body.

Increases blood flow

Increases blood flow

When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

Increase erections

Increase erections

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

Complete Viagra Treatment Guide

How Does Viagra Work?

Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis during sexual arousal. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required. The medication blocks the phosphodiesterase type 5 enzyme, allowing blood vessels to relax and improve circulation when you're sexually aroused.

Available Dosages and Options

Viagra is available in 25mg, 50mg, and 100mg tablets. Most men start with 50mg, which can be adjusted based on effectiveness and tolerability. At EverydayMeds, you can choose between branded Viagra or generic sildenafil at checkout - both contain the same active ingredient, with sildenafil offering a more cost-effective option.

Timing and Duration

Take Viagra 30-60 minutes before sexual activity on an empty stomach for best results. Fatty meals may delay its onset. The effects can last 4-6 hours, though this doesn't mean you'll have an erection for this entire period. Remember, only take one dose within any 24-hour period.

Who Can Take Viagra?

Viagra is suitable for adult men over 18 experiencing erectile dysfunction. However, it's not appropriate for everyone. Men taking nitrates for heart conditions, those with severe cardiovascular disease, or recent stroke/heart attack history should not use Viagra. Our online consultation process ensures the treatment is safe and suitable for your individual circumstances.

Getting Viagra Through EverydayMeds

Our UK-licensed prescribers conduct thorough clinical assessments to determine if Viagra is right for you. The consultation covers your medical history, current medications, and cardiovascular health. If approved, you can choose between branded Viagra or generic sildenafil, both offering the same therapeutic benefits with different pricing options.

What you need to know about erectile dysfunction

It's one of the most common conditions we treat, and one of the most treatable.

What is Erectile Dysfunction?
ED means finding it hard to get or keep an erection firm enough for sex. It's not unusual to have an off night; the point at which it's worth doing something is when it's happening regularly, or when it's starting to bother you.
How will I feel when I take ED medication?
For most men, nothing feels different day to day. The medication works in the background — when you're sexually aroused, it helps blood flow where it's needed, so erections come more easily and last longer. It doesn't cause arousal on its own. Some men notice mild, short-lived effects like a headache, facial flushing or a stuffy nose, which usually pass as the dose wears off.
Why do I need a prescription for ED medication?
ED treatments are prescription-only medicines in the UK because they aren't suitable for everyone — for example, alongside certain heart conditions or medications like nitrates. That's why we ask you to complete a short online consultation first. A UK-registered prescriber reviews your answers to make sure your chosen treatment is safe and right for you before it's dispensed.
