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.

Essential Viagra Information for UK Patients

How Does Viagra Work?

Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis during sexual arousal. It doesn't cause automatic erections but enhances your natural response to sexual stimulation. Effects typically begin within 30-60 minutes and may last up to 4-6 hours.

Choosing Between Viagra and Sildenafil

EverydayMeds offers both Pfizer's branded Viagra and generic sildenafil at checkout. Both contain identical active ingredients and work the same way. Generic sildenafil provides the same effectiveness at a lower cost, whilst branded Viagra offers the assurance of Pfizer's original formulation.

Dosage and Administration

Available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or 100mg if 50mg proves insufficient. Never exceed one dose per 24 hours.

Who Can Take Viagra?

Adult men with erectile dysfunction may be suitable candidates following clinical assessment. Our UK-licensed prescribers evaluate your medical history, current medications, and cardiovascular health. Men taking nitrates, with severe heart conditions, or recent stroke/heart attack typically cannot take sildenafil safely.

Common Side Effects

Mild side effects may include headaches, facial flushing, nasal congestion, or indigestion. These usually resolve as your body adjusts to treatment. Serious side effects are rare but require immediate medical attention, including prolonged erections lasting over four hours or sudden vision/hearing changes.

Getting Viagra Safely

Viagra requires prescription following consultation with qualified healthcare professionals. EverydayMeds provides confidential online consultations with UK-licensed prescribers who ensure treatment suitability and safety for your individual circumstances.

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.
