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 the Value Difference Between Options

What's the Actual Difference Between Viagra and Sildenafil?

The key difference lies in branding and cost rather than medical effectiveness. Viagra is Pfizer's branded version of sildenafil citrate, whilst sildenafil refers to the generic equivalent. Both contain exactly the same active ingredient in identical concentrations - 25mg, 50mg, or 100mg tablets. The medication works by inhibiting the PDE5 enzyme, which may help improve blood flow to the penis when sexually aroused. This means patients can expect similar results from either option when used as directed.

Cost Considerations and Value Assessment

Generic sildenafil typically costs significantly less than branded Viagra whilst providing the same therapeutic benefits. This price difference exists because generic manufacturers don't need to recoup the original research and development costs. For patients requiring ongoing treatment, choosing sildenafil over Viagra could result in substantial savings over time. EverydayMeds offers transparent pricing for both options, allowing you to compare costs during checkout and select the most suitable choice for your budget and preferences.

Clinical Effectiveness and Treatment Outcomes

Both Viagra and sildenafil demonstrate similar effectiveness rates in clinical studies. The medication typically begins working within 30-60 minutes of taking and effects may last 4-6 hours. However, this doesn't mean an erection will last this duration - the medication simply enables the body's natural response to sexual stimulation during this timeframe. Starting doses usually begin at 50mg, which can be adjusted to 25mg or 100mg based on individual response and any side effects experienced.

Safety Profile and Prescription Requirements

Whether choosing Viagra or sildenafil, both require the same safety considerations and prescription process. Our UK-licensed prescribers conduct thorough clinical assessments to ensure suitability, reviewing medical history, current medications, and cardiovascular health. Both medications are contraindicated with nitrates (such as GTN spray) due to dangerous interactions that could cause severe blood pressure drops. Common side effects may include headaches, flushing, or nasal congestion, occurring at similar rates regardless of whether patients choose branded or generic versions.

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.
