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 the original brand name medication manufactured by Pfizer, whilst generic sildenafil contains the exact same active ingredient (sildenafil citrate) but is produced by different pharmaceutical companies. Both work identically by blocking the PDE5 enzyme, which increases blood flow to the penis when sexually aroused. The key differences lie in packaging, appearance, and cost rather than therapeutic effect.

Clinical Effectiveness: Do They Work the Same?

Generic sildenafil demonstrates identical clinical effectiveness to branded Viagra because they contain the same active ingredient in the same concentrations (25mg, 50mg, or 100mg). Both typically work within 30-60 minutes of taking and can remain effective for 4-6 hours. The medication requires sexual stimulation to work - it doesn't cause automatic erections. Clinical studies consistently show no significant difference in effectiveness between branded and generic versions when prescribed appropriately.

Cost Considerations for UK Patients

Generic sildenafil generally costs substantially less than branded Viagra whilst providing the same therapeutic benefits. This cost difference exists because generic manufacturers don't need to recoup the original research and development expenses. For many UK patients, this makes treatment more accessible and affordable for long-term use. At EverydayMeds, you can choose between branded Viagra or generic sildenafil during checkout following your clinical assessment.

Safety and Regulation Standards

Both branded Viagra and generic sildenafil available in the UK must meet identical MHRA safety and quality standards. Generic versions undergo rigorous testing to demonstrate bioequivalence to the original branded medication. This means they're absorbed into your system at the same rate and to the same extent as Viagra. All versions require prescription from UK-licensed prescribers following clinical assessment.

Who Can Take Sildenafil Medication?

Whether choosing branded or generic, the same eligibility criteria apply. Sildenafil is suitable for adult men experiencing erectile dysfunction who complete a clinical assessment. It's not suitable for men taking nitrates (GTN spray), those with severe heart conditions, recent stroke or heart attack, or severe liver problems. Our UK-licensed prescribers evaluate your medical history, current medications, and cardiovascular health before prescribing either option.

Making Your Choice at EverydayMeds

At EverydayMeds, we understand that patient preference matters. Some men prefer the familiarity of the original Viagra brand, whilst others choose generic sildenafil for its cost-effectiveness. Both options undergo the same clinical assessment process with our UK-licensed prescribers. Following approval, you can select your preferred option during checkout. We ensure all medications are sourced from licensed UK suppliers and delivered discreetly to your address.

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.
