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 Branded vs Generic ED Medications

What's the Difference Between Viagra and Generic Sildenafil?

Viagra is Pfizer's brand name for sildenafil citrate, the original erectile dysfunction medication approved in 1998. Generic sildenafil contains exactly the same active ingredient at identical concentrations but is manufactured by different pharmaceutical companies once Pfizer's patent expired. The key differences lie in price, packaging, and tablet appearance rather than therapeutic effect.

Are Generic Versions as Effective as Branded Viagra?

Generic sildenafil demonstrates equivalent effectiveness to branded Viagra because both contain identical amounts of the same active ingredient. UK regulations require generic medications to prove bioequivalence to the original branded version, meaning they must deliver the same therapeutic effect in the body. Clinical studies consistently show no significant difference in effectiveness between branded and generic sildenafil for treating erectile dysfunction.

Safety and Quality Standards

Both branded Viagra and generic sildenafil available through UK pharmacies meet the same stringent safety and quality standards set by the Medicines and Healthcare products Regulatory Agency (MHRA). Generic manufacturers must demonstrate that their products contain the same active ingredient, strength, and dosage form as the branded version. All sildenafil medications, whether branded or generic, undergo rigorous testing for purity, potency, and quality.

Cost Considerations

Generic sildenafil typically costs significantly less than branded Viagra, often representing savings of 50-80% or more. This price difference occurs because generic manufacturers don't need to recoup research and development costs that went into creating the original medication. For patients requiring ongoing treatment, choosing generic sildenafil can result in substantial long-term savings without compromising effectiveness.

Choosing Between Branded and Generic Options

The choice between Viagra and generic sildenafil often comes down to personal preference and budget considerations. Some patients prefer the familiarity and reassurance of the original branded medication, while others prioritise the cost savings offered by generic alternatives. Both options require the same clinical assessment and prescription process through EverydayMeds.

Available Strengths and Dosing

Both branded Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately 30-60 minutes before sexual activity. Depending on effectiveness and tolerability, your prescriber may recommend adjusting to 25mg or increasing to 100mg. The maximum recommended frequency is once daily, regardless of whether you choose branded or generic options.

Clinical Assessment Process

Whether you choose Viagra or generic sildenafil, the prescription process remains identical. You'll complete a comprehensive clinical assessment covering your medical history, current medications, and cardiovascular health. This ensures sildenafil is safe and appropriate for your individual circumstances. The assessment helps identify any contraindications or potential drug interactions that could make treatment unsuitable.

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.
