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.

Viagra vs Sildenafil: Understanding Your Options

What's the Difference Between Viagra and Sildenafil?

Viagra is the original branded medication manufactured by Pfizer, whilst sildenafil is the generic equivalent. Both contain exactly the same active ingredient - sildenafil citrate - in identical concentrations of 25mg, 50mg, or 100mg. The key differences lie in appearance, packaging, and crucially, price. Generic sildenafil typically costs significantly less than branded Viagra, making it an attractive option for men seeking effective ED treatment without the premium price tag.

How Do Both Medications Work?

Whether you choose Viagra or generic sildenafil, the mechanism of action remains identical. Both work as PDE5 inhibitors, blocking the phosphodiesterase type 5 enzyme to increase blood flow to the penis during sexual arousal. Neither medication causes automatic erections - sexual stimulation is still required. The effects typically begin within 30-60 minutes and can last 4-6 hours, though this doesn't mean an erection persists for this duration.

Choosing Between Branded and Generic Options

When deciding between Viagra and sildenafil, consider your personal preferences and budget. Some men prefer the reassurance of the original branded medication, whilst others prioritise the cost savings offered by generic alternatives. Both undergo rigorous quality testing and contain the same active ingredient in identical doses. EverydayMeds offers both options, allowing you to choose based on your individual needs and preferences during the checkout process.

Where Can You Safely Purchase These Medications?

In the UK, both Viagra and sildenafil are prescription-only medicines (POM) that require consultation with a qualified healthcare professional. Licensed online pharmacies like EverydayMeds provide a convenient, discreet alternative to traditional face-to-face consultations. Our UK-licensed prescribers conduct thorough clinical assessments to ensure these medications are safe and appropriate for your individual circumstances.

The Consultation Process

Before prescribing either Viagra or sildenafil, healthcare professionals must evaluate your medical history, current medications, and cardiovascular health. This assessment is crucial because ED medications can interact dangerously with certain drugs, particularly nitrates used for heart conditions. The consultation also determines the most appropriate starting dose, typically 50mg, which can be adjusted based on effectiveness and any side effects experienced.

Safety Considerations and Contraindications

Both Viagra and sildenafil carry the same contraindications and safety warnings. They should not be used by men taking nitrate medications, those with severe heart disease, recent stroke or heart attack, severe liver problems, or very low blood pressure. Always disclose all medications and health conditions during your consultation to ensure safe prescribing.

Value and Cost Considerations

Generic sildenafil offers exceptional value, providing the same therapeutic benefits as branded Viagra at a fraction of the cost. This makes long-term ED treatment more affordable and accessible. Many men find that choosing generic sildenafil allows them to maintain their treatment regimen without financial strain, potentially improving their overall quality of life and relationship satisfaction.

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.
