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 Sildenafil Quality

Identical Active Ingredients, Different Prices

The fundamental difference between branded Viagra and generic sildenafil 100mg lies in cost rather than effectiveness. Both medications contain exactly the same active ingredient - sildenafil citrate - in identical concentrations. Generic sildenafil undergoes the same rigorous manufacturing standards and quality controls as branded Viagra, ensuring consistent potency and safety. The MHRA requires generic medications to demonstrate bioequivalence to branded versions, meaning they must deliver the same therapeutic effects in your body.

Price differences occur because generic manufacturers don't bear the original research and development costs that Pfizer invested in creating Viagra. Once patent protection expires, multiple pharmaceutical companies can produce generic versions, creating healthy competition that drives prices down whilst maintaining quality standards.

Clinical Effectiveness: Branded vs Generic

Clinical studies consistently demonstrate that generic sildenafil 100mg produces identical therapeutic outcomes to branded Viagra. Both work by inhibiting the PDE5 enzyme, increasing blood flow to the penis when sexually aroused. The onset time (30-60 minutes), duration of action (4-6 hours), and success rates remain equivalent between branded and generic formulations.

Men switching from branded Viagra to generic sildenafil typically experience no difference in effectiveness or side effect profiles. The same precautions apply to both versions - taking on an empty stomach for faster onset, avoiding excessive alcohol consumption, and maintaining the 24-hour dosing interval. Whether you choose branded or generic, the 100mg strength represents the maximum recommended dose for most men.

Quality Assurance and Regulatory Standards

Both branded Viagra and generic sildenafil sold in the UK must meet identical regulatory standards set by the MHRA. Generic manufacturers must prove their products contain the correct amount of active ingredient, dissolve at the same rate, and produce equivalent blood levels as the branded version. These bioequivalence studies ensure generic sildenafil performs identically in clinical practice.

GPhC-registered pharmacies like EverydayMeds source generic sildenafil from licensed manufacturers who maintain the same quality systems required for branded medications. The manufacturing facilities undergo regular inspections, and each batch receives quality testing before release. This regulatory framework ensures patients receive consistent, effective treatment regardless of whether they choose branded or generic options.

Cost Considerations and Value

Generic sildenafil 100mg typically costs significantly less than branded Viagra whilst delivering identical therapeutic benefits. This cost difference can be substantial over time, particularly for men requiring regular treatment. The savings allow many patients to access effective ED treatment who might otherwise find branded options financially prohibitive.

Some men prefer branded Viagra for psychological reasons, feeling more confident in the original formulation despite identical clinical effects. EverydayMeds respects this preference by offering both options at checkout, allowing patients to choose based on their personal priorities and budget considerations. Neither choice compromises treatment effectiveness or safety when obtained through legitimate prescription channels.

Side Effects and Safety Profiles

The side effect profile remains identical between branded Viagra and generic sildenafil 100mg. Common side effects include headache, facial flushing, indigestion, and nasal congestion, occurring at the same frequency regardless of manufacturer. The same contraindications apply - particularly the dangerous interaction with nitrate medications that can cause life-threatening blood pressure drops.

Serious side effects like priapism (painful erections lasting over 4 hours) or sudden vision changes require immediate medical attention with both branded and generic formulations. The identical safety profile means prescribers use the same clinical assessment criteria when recommending either option, evaluating cardiovascular health, current medications, and medical history.

Making Your Choice: Branded or Generic?

The decision between branded Viagra and generic sildenafil 100mg often comes down to personal preference and budget rather than clinical differences. Both require the same prescription process, clinical assessment, and follow-up care. Some patients value the reassurance of the original branded product, whilst others prefer maximising value with generic alternatives.

EverydayMeds streamlines this decision by offering both options through the same convenient ordering process. After completing your clinical assessment with our UK-registered prescribers, you can select your preferred option at checkout. This flexibility ensures you receive effective ED treatment that aligns with your preferences and financial considerations whilst maintaining the highest safety standards.

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.
