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.

Understanding Your Sildenafil and Viagra Options

What's the Difference Between Viagra and Sildenafil?

Viagra is the original brand name medication manufactured by Pfizer, whilst sildenafil refers to the generic version containing the identical active ingredient - sildenafil citrate. Both medications work through the same mechanism, blocking the PDE5 enzyme to increase blood flow to the penis when sexually aroused. The clinical effectiveness, onset time (30-60 minutes), and duration of action (4-6 hours) remain identical between branded and generic versions.

Cost Comparison: Generic vs Branded

Generic sildenafil typically costs considerably less than branded Viagra, often representing savings of 60-80% whilst maintaining identical therapeutic effects. This cost difference exists because generic manufacturers don't need to recoup the original research and development costs. For men requiring ongoing ED treatment, these savings can be substantial over time. EverydayMeds provides transparent pricing for both options, allowing you to compare costs during the checkout process.

Over-the-Counter Options

Viagra Connect (sildenafil 50mg) became available over-the-counter from UK pharmacies, though this requires a consultation with a registered pharmacist. However, prescription options through online consultations often provide better value and access to different dosage strengths (25mg, 50mg, 100mg) that may be better suited to individual needs following proper medical assessment.

Clinical Effectiveness and Safety

Both Viagra and generic sildenafil undergo the same rigorous manufacturing standards and contain identical active ingredients. Clinical studies demonstrate equivalent effectiveness rates between branded and generic formulations. The Medicines and Healthcare products Regulatory Agency (MHRA) ensures generic medications meet the same safety and quality standards as original branded medicines. Common side effects, contraindications, and drug interactions remain identical for both options.

Choosing Between Viagra and Sildenafil

The choice between branded Viagra and generic sildenafil often comes down to personal preference and budget considerations. Some men prefer the branded option for peace of mind, whilst others choose generic sildenafil for the cost savings. Both require the same clinical assessment to ensure suitability, checking for contraindications like nitrate medications, severe heart conditions, or significant drug interactions. Your prescriber can help determine the most appropriate dosage strength based on your individual circumstances.

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.
