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 Viagra vs Sildenafil: Same Medicine, Different Costs

What's the Difference Between Viagra and Sildenafil?

The fundamental difference between Viagra and sildenafil lies in branding and cost rather than effectiveness. Viagra is the original brand name medication manufactured by Pfizer, whilst sildenafil is the generic version containing the same active ingredient - sildenafil citrate. Both medications work identically by inhibiting the PDE5 enzyme, which helps increase blood flow to the penis when sexually aroused.

Cost Considerations: Why Choose Generic Sildenafil?

Generic sildenafil offers significant cost savings compared to branded Viagra, often costing substantially less per tablet. This price difference exists because generic manufacturers don't need to recoup the original research and development costs. For men requiring ongoing treatment, these savings can be considerable over time. The lower cost doesn't compromise effectiveness - generic medications must meet the same strict regulatory standards as branded versions.

Clinical Effectiveness: No Difference in Performance

Both Viagra and generic sildenafil contain identical amounts of the active ingredient and work in exactly the same way. Clinical studies consistently show equivalent effectiveness between branded and generic versions. Both typically begin working within 30-60 minutes of taking and can remain effective for 4-6 hours. The choice between branded and generic often comes down to personal preference and budget considerations rather than medical effectiveness.

Prescription Requirements and Safety

Both Viagra and sildenafil are prescription-only medicines in the UK, requiring consultation with a licensed prescriber. This clinical assessment ensures the medication is safe and appropriate for your individual circumstances. The prescriber will review your medical history, current medications, and cardiovascular health before determining suitability. Common starting doses include 25mg, 50mg, or 100mg, with 50mg being typical for most men.

Over-the-Counter Options

Viagra Connect (50mg sildenafil) is available over-the-counter from UK pharmacies without prescription, though this requires consultation with a qualified pharmacist. However, prescription options often provide greater flexibility in dosing and may be more cost-effective for regular use, particularly when choosing generic sildenafil.

Making Your Choice at EverydayMeds

EverydayMeds offers both branded Viagra and generic sildenafil, allowing you to choose based on your preferences and budget. Both options undergo the same rigorous clinical assessment process to ensure safety and suitability. Many patients find generic sildenafil provides excellent value without compromising on quality or effectiveness. The choice ultimately depends on whether brand preference or cost savings are more important to 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.
