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.

Comparing Your ED Treatment Options: Value vs Brand

Understanding the Difference Between Viagra and Sildenafil

Both Viagra and sildenafil contain the identical active ingredient - sildenafil citrate. Viagra is the original branded medication manufactured by Pfizer, whilst sildenafil is the generic equivalent. The clinical effectiveness, dosing, and safety profile remain identical between both options. The primary difference lies in cost, with generic sildenafil typically offering substantial savings compared to the branded version.

How Both Medications Work

Sildenafil (whether branded as Viagra or generic) works as a PDE5 inhibitor, blocking the phosphodiesterase type 5 enzyme to increase blood flow to the penis during sexual arousal. Neither medication causes automatic erections - sexual stimulation remains necessary. Both typically begin working within 30-60 minutes of taking and effects may last 4-6 hours, though this doesn't mean erections persist for this duration.

Available Dosage Options

Both Viagra and sildenafil are available in 25mg, 50mg, and 100mg strengths. The typical starting dose is 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if the 50mg dose proves insufficient. Only one dose should be taken within any 24-hour period, and fatty meals may delay the medication's onset of action.

Clinical Assessment and Eligibility

EverydayMeds requires all patients to complete a comprehensive clinical assessment before prescribing either Viagra or sildenafil. Our UK-licensed prescribers evaluate your cardiovascular health, current medications, and medical history to ensure safe prescribing. This assessment determines your suitability for sildenafil-based treatment and helps identify the most appropriate dosage for your individual circumstances.

Safety Considerations and Contraindications

Both Viagra and sildenafil share identical contraindications and safety profiles. These medications should not be used alongside nitrate medications (such as GTN spray), riociguat, or by individuals with severe cardiovascular conditions, recent heart attacks or strokes, severe liver impairment, or very low blood pressure. Alpha-blockers, some antifungal medications, and certain HIV treatments may require dosage adjustments or careful monitoring.

Making the Right Choice for You

When deciding between Viagra and sildenafil, consider that both offer identical therapeutic benefits. Generic sildenafil provides excellent value whilst maintaining the same quality standards and effectiveness as branded Viagra. Some patients prefer the reassurance of the original brand, whilst others prioritise cost-effectiveness. EverydayMeds allows you to choose between both options during checkout, ensuring you receive the treatment that best suits your preferences and budget. Our discreet packaging and next-day delivery service applies to both branded and generic options, maintaining your privacy throughout the treatment process.

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.
