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.

Quick Solutions for Common British Viagra Problems

MHRA Licensing and Legal Requirements

All legitimate British Viagra suppliers must hold valid MHRA (Medicines and Healthcare products Regulatory Agency) licences. EverydayMeds operates under full UK regulatory compliance, ensuring you receive genuine Pfizer Viagra or approved generic sildenafil. Both medications contain the same active ingredient - patients can choose between branded or generic options at checkout based on preference and budget.

Prescription Requirements Under UK Law

British Viagra requires a valid prescription from a UK-licensed prescriber. This applies to both branded Viagra and generic sildenafil formulations. The clinical assessment evaluates cardiovascular health, current medications, and medical history to ensure safe treatment. Viagra Connect (50mg) may be available over-the-counter from pharmacies for eligible patients, though prescription options offer greater dosage flexibility.

Common Dosage and Effectiveness Issues

If British Viagra isn't working effectively, several factors may be involved. Food, particularly fatty meals, can delay onset by up to 60 minutes. Alcohol consumption reduces effectiveness and may cause side effects. The standard starting dose is 50mg, but this can be adjusted to 25mg or 100mg based on response and tolerability. Never exceed one dose per 24-hour period.

Timing and Administration Problems

Take British Viagra 30-60 minutes before sexual activity for optimal results. The medication requires sexual stimulation to work - it doesn't cause automatic erections. Effects typically last 4-6 hours, though this doesn't mean erections persist throughout this period. If timing remains problematic, discuss alternatives with your prescriber.

Contraindications and Safety Warnings

British Viagra is contraindicated with nitrate medications (GTN spray, isosorbide) due to dangerous blood pressure interactions. Patients with severe cardiovascular disease, recent heart attack or stroke, or severe liver impairment should not use sildenafil. Always inform prescribers about all current medications and health conditions during assessment.

When to Contact Your Prescriber

Contact your prescriber if you experience chest pain, prolonged erections (over 4 hours), sudden vision or hearing loss, or severe side effects. Dose adjustments may be needed if standard strengths prove ineffective or cause unwanted effects. EverydayMeds provides ongoing clinical support for treatment optimisation.

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.
