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.

How Viagra Works: The Science Behind ED Treatment

Understanding How Viagra Works for Erectile Dysfunction

Viagra contains the active ingredient sildenafil citrate, which belongs to a class of medicines called PDE5 inhibitors. When you become sexually aroused, your body naturally releases nitric oxide, which helps relax the blood vessels in your penis. Viagra works by blocking the PDE5 enzyme that would normally break down this process, allowing increased blood flow to the penis. This enhanced circulation helps you achieve and maintain an erection suitable for sexual activity.

Getting Started with Viagra Through EverydayMeds

Accessing Viagra treatment through EverydayMeds is straightforward and convenient. Start by completing our confidential online consultation form, which takes just a few minutes. Our UK-licensed prescribers will review your medical history and current medications to ensure Viagra is suitable for you. The assessment covers important factors like cardiovascular health, current medicines, and any contraindications that might affect your treatment.

Once approved, you can choose between branded Viagra or generic Sildenafil at checkout. Both contain the same active ingredient and work identically - the generic version simply offers a more cost-effective option. Your treatment will be dispensed by our registered UK pharmacy and sent with fast, discreet delivery.

What to Expect When Taking Viagra

Viagra typically starts working within 30-60 minutes of taking the tablet, though this can vary between individuals. The effects may last up to 4-6 hours, but this doesn't mean you'll have an erection for this entire period. Sexual stimulation is still required for the medication to work - Viagra doesn't cause automatic erections. For best results, avoid large or fatty meals before taking Viagra, as these can delay how quickly it works.

The usual starting dose is 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg or 100mg depending on how well you respond to treatment and any side effects you might experience. Never take more than one dose in 24 hours, regardless of the strength prescribed.

Who Can Take Viagra and Important Safety Information

Viagra is suitable for adult men experiencing erectile dysfunction, but it's not appropriate for everyone. During your consultation, our prescribers will check for conditions that might make Viagra unsuitable, such as severe heart disease, recent heart attack or stroke, very low blood pressure, or severe liver problems. Certain medications, particularly nitrates used for chest pain, can interact dangerously with Viagra.

Common side effects may include headache, facial flushing, indigestion, or nasal congestion. These are usually mild and temporary. If you experience any severe side effects or an erection lasting more than four hours, seek immediate medical attention.

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.
