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.

Comparing Sildenafil Costs: Generic vs Branded Options

Understanding Sildenafil BNF Cost Structure

The British National Formulary (BNF) provides standardised pricing for both generic sildenafil and branded Viagra, helping patients understand treatment costs. Generic sildenafil typically costs significantly less than the branded alternative whilst containing the same active ingredient - sildenafil citrate. This PDE5 inhibitor works by increasing blood flow to the penis during sexual arousal, with both formulations offering identical clinical effectiveness.

Cost-Effectiveness Analysis of ED Treatment Options

When comparing treatment costs, generic sildenafil offers substantial savings over branded alternatives. Available in 25mg, 50mg, and 100mg strengths, patients can choose the most appropriate dosage following clinical assessment. The typical starting dose is 50mg, taken 30-60 minutes before sexual activity. EverydayMeds provides both generic sildenafil and branded Viagra options, allowing patients to select based on personal preference and budget considerations.

Clinical Equivalence and Quality Assurance

Generic sildenafil undergoes rigorous testing to ensure bioequivalence with the branded version. UK-licensed medications must meet identical safety and efficacy standards regardless of manufacturer. This means patients receive the same therapeutic benefits whether choosing generic or branded options. Our registered pharmacy sources all medications from licensed UK suppliers, ensuring consistent quality and regulatory compliance.

Choosing Between Generic and Branded Sildenafil

Factors influencing choice between generic sildenafil and branded Viagra often centre on cost considerations and personal preference. Both options require prescription following online consultation with our UK-registered prescribers. The clinical assessment evaluates medical history, current medications, and cardiovascular health to ensure treatment suitability. Patients with conditions such as severe heart disease, those taking nitrate medications, or with recent stroke history may not be suitable candidates for sildenafil treatment.

Maximising Treatment Value

To optimise cost-effectiveness, patients should consider starting with the recommended 50mg dose, which can be adjusted based on response and tolerability. Taking sildenafil on an empty stomach may improve effectiveness, whilst avoiding alcohol and fatty foods can enhance treatment outcomes. The medication's effects typically last 4-6 hours, with maximum dosing frequency of once per 24 hours. Regular review with healthcare providers ensures continued treatment appropriateness and optimal cost-benefit outcomes.

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.
