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

Active Ingredient Comparison

Both Viagra and generic sildenafil contain sildenafil citrate as their active ingredient. This PDE5 inhibitor works by increasing blood flow to the penis during sexual arousal, helping achieve and maintain erections. The mechanism of action remains identical whether you choose branded Viagra manufactured by Pfizer or generic sildenafil from licensed pharmaceutical companies. Clinical studies demonstrate equivalent bioavailability and therapeutic effects between branded and generic formulations.

Cost Considerations

Generic sildenafil typically costs significantly less than branded Viagra, making it an attractive option for ongoing treatment. This cost difference exists because generic manufacturers don't need to recoup research and development expenses that original brand developers invested. At EverydayMeds, patients can compare prices between branded and generic options during checkout, allowing informed decisions based on budget and personal preferences.

Quality and Regulatory Standards

Both branded Viagra and generic sildenafil available through UK pharmacies must meet identical MHRA regulatory standards. Generic medications undergo rigorous testing to demonstrate bioequivalence to the original branded product. This means generic sildenafil must prove it delivers the same amount of active ingredient into the bloodstream at the same rate as branded Viagra. UK-approved generics maintain the same quality, safety, and efficacy standards as their branded counterparts.

Dosage and Administration

Whether choosing Viagra or generic sildenafil, the same dosing guidelines apply. Both are available in 25mg, 50mg, and 100mg strengths. The typical starting dose is 50mg, taken approximately 30-60 minutes before sexual activity. Maximum dosing frequency remains one tablet per 24-hour period for both options. Food intake, particularly fatty meals, can delay onset for both branded and generic formulations.

Effectiveness and Duration

Clinical effectiveness remains consistent between Viagra and generic sildenafil. Both can help improve erectile function for 4-6 hours after administration, though this doesn't mean erections persist for this entire duration. Sexual stimulation remains necessary for both medications to work effectively. Response rates and improvement in erectile function show no clinically significant differences between branded and generic versions in peer-reviewed studies.

Patient Choice at EverydayMeds

EverydayMeds recognises that medication preferences vary between individuals. Some patients prefer branded medications for psychological confidence, while others prioritise cost-effectiveness with generics. Both options undergo the same clinical assessment process with UK-licensed prescribers. During checkout, patients can select their preferred option based on personal circumstances and treatment goals. This flexibility ensures treatment remains accessible while respecting individual preferences.

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.
