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 Viagra vs Sildenafil: The Key Differences

What's the Difference Between Viagra and Sildenafil?

Viagra is the original brand name medication manufactured by Pfizer, whilst sildenafil is the generic version containing exactly the same active ingredient. Think of it like branded paracetamol versus generic paracetamol - the therapeutic effect is identical, but the price differs considerably. Both medications work by blocking the PDE5 enzyme, increasing blood flow to the penis when sexually aroused.

Does Viagra Make You Last Longer Than Sildenafil?

Neither Viagra nor sildenafil directly affects ejaculation timing or helps you "last longer" during sexual activity. Both medications specifically treat erectile dysfunction by helping achieve and maintain erections when sexually stimulated. The effects can last 4-6 hours, but this refers to the window during which the medication may help with erections, not the duration of sexual activity itself.

Effectiveness: Branded vs Generic

Clinical studies consistently show that generic sildenafil demonstrates identical effectiveness to branded Viagra. Both contain the same concentration of active ingredient and must meet identical regulatory standards set by the MHRA. The bioavailability - how much medication reaches your bloodstream - is equivalent between branded and generic versions.

Cost Considerations

Generic sildenafil typically costs 60-80% less than branded Viagra whilst delivering identical therapeutic benefits. For example, whilst Viagra 50mg might cost £6-8 per tablet, generic sildenafil 50mg could cost £1-3 per tablet. Over time, this price difference becomes substantial, particularly for men requiring regular treatment.

Which Should You Choose?

The choice between Viagra and sildenafil often comes down to personal preference and budget. Some men prefer the reassurance of the original branded medication, whilst others appreciate the significant cost savings of generic sildenafil. Both require the same clinical assessment process and have identical dosing schedules - typically 50mg taken 30-60 minutes before sexual activity.

Safety and Quality Standards

Both Viagra and generic sildenafil sold through UK-licensed pharmacies like EverydayMeds meet stringent quality standards. Generic medications must demonstrate bioequivalence to the original branded version before receiving MHRA approval. This ensures identical safety profiles, effectiveness, and quality between branded and generic options.

Getting Started with Treatment

Whether you choose Viagra or sildenafil, you'll need to complete a clinical assessment with a UK-licensed prescriber. This evaluation considers your medical history, current medications, and cardiovascular health to ensure safe treatment. EverydayMeds offers both options, allowing you to make your choice during the ordering process based on your preferences and budget.

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.
