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.

Duration Comparison: Viagra vs Sildenafil Options

Understanding ED Treatment Duration

Both Viagra and generic sildenafil contain sildenafil citrate as the active ingredient, meaning they offer identical duration and effectiveness. The medication typically begins working within 30-60 minutes and may remain effective for 4-6 hours. This timeframe represents the window during which the medication can help achieve an erection when sexually aroused, not the duration of any single erection.

Branded vs Generic: What's the Difference?

Viagra, manufactured by Pfizer, was the original branded version of sildenafil. Generic sildenafil contains the same active ingredient in identical concentrations but costs significantly less. Many patients choose generic sildenafil for this reason, as it provides the same clinical benefits at a more affordable price point. EverydayMeds offers both options, allowing patients to select based on their preferences and budget.

Dosage Options and Duration

Both Viagra and sildenafil are available in 25mg, 50mg, and 100mg strengths. Most patients start with 50mg, which can be adjusted based on effectiveness and tolerability. Higher doses don't necessarily extend duration but may improve effectiveness for some individuals. The maximum recommended frequency is one dose per 24-hour period, regardless of strength chosen.

Factors Affecting Duration

Several factors can influence how long sildenafil works effectively. Age, overall health, other medications, and lifestyle factors all play a role. Food intake, particularly fatty meals, can delay the onset of action but doesn't significantly affect total duration. Alcohol consumption may reduce effectiveness and is best minimised when taking ED medication.

Getting ED Treatment Online

EverydayMeds provides convenient access to both Viagra and sildenafil following online consultation with UK-licensed prescribers. The clinical assessment evaluates medical history, current medications, and suitability for treatment. Once approved, patients can choose between branded Viagra or generic sildenafil based on their preferences, with discreet delivery across the UK.

Safety Considerations

Sildenafil is generally well-tolerated but isn't suitable for everyone. Men taking nitrate medications or with certain cardiovascular conditions shouldn't use sildenafil-based treatments. The online consultation process helps identify any contraindications and ensures safe prescribing. Common side effects may include headache, flushing, or indigestion, typically mild and temporary.

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.
