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 to Access Sildenafil Through EverydayMeds

Understanding BNF Sildenafil Prescription Requirements

The British National Formulary (BNF) classifies sildenafil as a prescription-only medicine (POM) for erectile dysfunction treatment in the UK. To legally obtain sildenafil, you must receive a valid prescription from a UK-licensed healthcare professional following a thorough clinical assessment. EverydayMeds streamlines this process through our regulated online consultation service, making it convenient to access treatment whilst maintaining the highest safety standards.

Online Consultation Process

Our straightforward consultation begins with a comprehensive medical questionnaire covering your symptoms, medical history, and current medications. This assessment helps our UK-licensed prescribers determine whether sildenafil is suitable for your individual circumstances. The consultation typically takes 5-10 minutes and follows strict BNF guidelines to ensure your safety. You'll receive a decision within hours, not days.

Sildenafil Dosage Options Available

Following BNF recommendations, sildenafil is available in three strengths: 25mg, 50mg, and 100mg tablets. Most patients start with the standard 50mg dose, taken approximately one hour before sexual activity. Your prescriber may recommend adjusting the dose based on effectiveness and any side effects experienced. The maximum recommended frequency is once daily, with effects typically lasting 4-6 hours.

Choose Between Generic and Branded Options

EverydayMeds offers both generic sildenafil and branded Viagra, allowing you to choose based on your preferences and budget. Both contain the same active ingredient (sildenafil citrate) and work identically. Generic sildenafil provides the same clinical effectiveness as Viagra but at a more affordable price point. At checkout, you can select your preferred option without any difference in our consultation process.

Safety Considerations and Contraindications

The BNF outlines specific contraindications for sildenafil use. Our prescribers carefully screen for conditions that may make sildenafil unsuitable, including severe cardiovascular disease, concurrent nitrate medication use, or significant liver impairment. We also check for potential drug interactions, particularly with blood pressure medications and alpha-blockers. This thorough assessment ensures sildenafil is both safe and appropriate for your circumstances.

Fast, Discreet UK Delivery

Once approved, your sildenafil prescription is dispensed by our UK-registered pharmacy and dispatched the same day for next-day delivery. All packages arrive in plain, confidential packaging with no indication of contents. We offer various delivery options including standard post, tracked delivery, and nominated day services to suit your schedule and privacy requirements.

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.
