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 Guide: Dosing, Safety & Support

Getting Started with Viagra Treatment

Viagra requires a prescription following consultation with a UK-licensed prescriber. Our clinical assessment evaluates your medical history, current medications, and cardiovascular health to ensure safe treatment. You can choose between branded Viagra or generic sildenafil - both contain the same active ingredient with identical effectiveness.

Proper Dosing and Administration

The standard starting dose is 50mg, taken 30-60 minutes before sexual activity. Your dose may be adjusted to 25mg or 100mg based on effectiveness and tolerability. Take only one dose per 24-hour period. Avoid fatty meals which can delay absorption and reduce effectiveness.

Important Safety Considerations

Never combine Viagra with nitrate medications (GTN spray, isosorbide) as this can cause dangerous drops in blood pressure. Inform your prescriber about all medications you're taking, including heart medications, blood pressure treatments, and alpha-blockers which may require dose adjustments.

Common Side Effects and Management

Mild side effects may include headache, facial flushing, or nasal congestion. These typically resolve within a few hours. If you experience chest pain, prolonged erection lasting over 4 hours, or sudden vision changes, seek immediate medical attention.

When to Contact Your Prescriber

Reach out if your current dose isn't effective after several attempts, you're experiencing bothersome side effects, or your health status changes. Our team can review your treatment and make necessary adjustments to optimise your results safely.

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.
