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 the Key Differences Between Viagra and Sildenafil

What Makes Viagra and Sildenafil Different?

Viagra is the original brand name medication manufactured by Pfizer, whilst sildenafil refers to the generic version containing the identical active ingredient. Both medications work in exactly the same way as PDE5 inhibitors, blocking the phosphodiesterase type 5 enzyme to increase blood flow to the penis when sexually aroused. The key differences lie in manufacturing, appearance, and cost rather than therapeutic effect.

Quality and Manufacturing Standards

Generic sildenafil manufactured for the UK market must meet the same stringent quality standards as branded Viagra. The Medicines and Healthcare products Regulatory Agency (MHRA) requires generic medications to demonstrate bioequivalence to the original branded version. This means generic sildenafil must deliver the same amount of active ingredient to your bloodstream at the same rate as Viagra. Licensed manufacturers must follow Good Manufacturing Practice guidelines, ensuring consistent quality and safety.

Price Comparison and Value Considerations

The most significant difference between Viagra and sildenafil is cost. Generic sildenafil typically costs substantially less than branded Viagra whilst providing identical therapeutic effects. This price difference exists because generic manufacturers don't need to recoup research and development costs that Pfizer invested in originally developing the medication. For many patients, choosing generic sildenafil represents excellent value without compromising on effectiveness or safety.

Available Dosages and Treatment Options

Both Viagra and sildenafil are available in 25mg, 50mg, and 100mg strengths. Your prescriber will typically recommend starting with 50mg, which can be adjusted based on effectiveness and tolerability. The medication should be taken 30-60 minutes before sexual activity, with effects potentially lasting 4-6 hours. Remember that sexual stimulation is still required - neither medication causes automatic erections.

Clinical Assessment and Prescription Requirements

Whether you choose Viagra or sildenafil, both require prescription following consultation with a UK-licensed prescriber. At EverydayMeds, our clinical assessment evaluates your medical history, current medications, and cardiovascular health to ensure safe prescribing. This assessment helps identify any contraindications, such as concurrent use of nitrate medications or severe heart conditions that would make treatment unsuitable.

Making Your Choice: Branded vs Generic

Many patients choose generic sildenafil for its cost-effectiveness, whilst others prefer the familiarity of the Viagra brand. Both options are equally effective when sourced from licensed UK pharmacies. Some patients report feeling more confident with branded medications, whilst others appreciate the significant cost savings of generics. The choice often comes down to personal preference and budget considerations rather than clinical differences.

Safety Considerations for Both Options

Both Viagra and sildenafil carry identical safety profiles and contraindications. Neither should be used with nitrate medications, and both require caution in patients with cardiovascular conditions. Common side effects may include headaches, flushing, or indigestion, regardless of which version you choose. Always follow prescribing instructions and never exceed one dose per 24-hour period.

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.
