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: 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 equivalent containing the identical active ingredient - sildenafil citrate. Both work as PDE5 inhibitors, increasing blood flow to the penis when sexually aroused. The clinical effectiveness, safety profile, and mechanism of action are identical between branded and generic versions.

Cost Comparison and Value

Generic sildenafil typically costs significantly less than branded Viagra, often representing savings of 60-80% whilst maintaining the same therapeutic benefits. This makes sildenafil an attractive option for men seeking cost-effective ED treatment without compromising on quality. At EverydayMeds, we offer both options at competitive prices, allowing you to choose based on your personal preference and budget considerations.

Quality and Regulatory Standards

Both Viagra and generic sildenafil available through UK pharmacies must meet identical regulatory standards set by the Medicines and Healthcare products Regulatory Agency (MHRA). Generic medications undergo rigorous bioequivalence testing to ensure they deliver the same therapeutic effect as the original branded version. This means you can expect the same onset time (30-60 minutes), duration of action (4-6 hours), and effectiveness regardless of which option you choose.

Dosage Options and Flexibility

Both Viagra and sildenafil are available in three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately one hour before sexual activity. Based on individual response and tolerability, your prescriber may adjust the dose to 25mg (if side effects occur) or increase to 100mg (if 50mg proves insufficient). The maximum recommended frequency is one dose per 24-hour period.

Prescription Requirements and Safety

Whether you choose Viagra or sildenafil, both require a prescription following consultation with a qualified healthcare provider. This ensures the medication is suitable for your individual health profile and doesn't interact with any existing medications or medical conditions. Our online consultation service allows you to complete this process discretely from home, with UK-licensed prescribers reviewing your medical history and current health status.

Choosing Between Viagra and Sildenafil

Your choice between branded Viagra and generic sildenafil often comes down to personal preference and budget considerations. Some patients prefer the familiarity and brand recognition of Viagra, whilst others prioritise the cost savings offered by generic sildenafil. Both options provide the same therapeutic benefits for treating erectile dysfunction when used as directed.

Our platform allows you to choose between Viagra and sildenafil during the ordering process, ensuring you receive the option that best meets your needs.

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.
