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 and Dosage Information

Understanding Viagra Treatment

Viagra is a PDE5 inhibitor that works by increasing blood flow to the penis during sexual arousal. The medication blocks the phosphodiesterase type 5 enzyme, which allows blood vessels to relax and expand. Importantly, Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.

Dosage and Administration

Viagra is typically prescribed starting at 50mg, taken approximately one hour before sexual activity. Depending on effectiveness and tolerability, your prescriber may adjust the dose to 25mg or increase to 100mg. Only one tablet should be taken within any 24-hour period. Taking Viagra with fatty meals may delay its onset of action, so consider timing around food intake.

Viagra vs Sildenafil: Your Choice

At EverydayMeds, patients can choose between Viagra (the original branded version) and Sildenafil (the generic alternative) at checkout. Both contain identical active ingredients and work in exactly the same way. The main difference is cost - generic Sildenafil offers the same clinical benefits at a lower price point, whilst Viagra is the original formulation from Pfizer.

Eligibility and Safety Considerations

Viagra requires a prescription following consultation with a UK-licensed prescriber. The clinical assessment evaluates your cardiovascular health, current medications, and medical history to ensure safe prescribing. Men taking nitrates for heart conditions, those with severe heart disease, or recent stroke/heart attack history may not be suitable candidates for Viagra treatment.

Getting Viagra Through EverydayMeds

Our online consultation process involves completing a comprehensive medical questionnaire reviewed by qualified UK prescribers. If treatment is deemed appropriate, you can choose between Viagra or Sildenafil at checkout. All medications are dispensed from UK-registered pharmacies and delivered discreetly to your chosen address.

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.
