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 Sildenafil Pricing and Clinical Value

BNF Listed Sildenafil: Generic vs Branded Options

The British National Formulary lists sildenafil as an effective PDE5 inhibitor for treating erectile dysfunction. EverydayMeds provides both branded Viagra and generic sildenafil options, allowing patients to choose based on their preferences and budget considerations. Generic sildenafil contains the same active ingredient as Viagra but typically costs 70-80% less than the branded version.

Clinical Effectiveness Comparison

Both generic sildenafil and branded Viagra demonstrate identical clinical outcomes when treating erectile dysfunction. The active ingredient, sildenafil citrate, works by increasing blood flow to the penis during sexual arousal. Available in 25mg, 50mg, and 100mg strengths, both formulations show equivalent bioavailability and therapeutic effectiveness. Clinical studies confirm that patients experience similar response rates, duration of action, and side effect profiles regardless of whether they choose branded or generic versions.

Cost Analysis and Value Proposition

Generic sildenafil represents exceptional value for money when treating erectile dysfunction. While maintaining identical therapeutic benefits to Viagra, the generic option reduces treatment costs significantly. This cost difference stems from expired patent protection, allowing multiple manufacturers to produce sildenafil without brand development expenses. Patients requiring long-term ED treatment can achieve substantial savings by selecting generic sildenafil while maintaining the same clinical outcomes.

Prescribing Guidelines and Recommendations

UK prescribing guidelines encourage generic prescribing to optimise healthcare resources without compromising patient care. The BNF supports generic substitution when clinically appropriate, recognising that identical active ingredients provide equivalent therapeutic benefits. EverydayMeds follows these guidelines by offering both options, ensuring patients can access cost-effective treatment that suits their individual circumstances and preferences.

Dosage Options and Treatment Flexibility

Both branded and generic sildenafil offer identical dosing flexibility, with 25mg, 50mg, and 100mg tablets available. Treatment typically begins with 50mg taken approximately one hour before sexual activity, with dosage adjustments based on effectiveness and tolerability. The maximum recommended dose is 100mg within any 24-hour period. This dosing flexibility ensures optimal treatment outcomes regardless of whether patients choose branded or generic formulations.

Quality Standards and Regulatory Compliance

Generic sildenafil available through EverydayMeds meets identical regulatory standards to branded Viagra. All medications undergo rigorous quality testing and comply with MHRA regulations ensuring safety, efficacy, and consistent pharmaceutical standards. Patients can confidently choose generic sildenafil knowing it maintains the same quality standards as branded alternatives while offering superior value for money.

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.
