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 Effectiveness & Treatment Options

Viagra Effectiveness Rates in Clinical Studies

Clinical trials consistently demonstrate that Viagra achieves effectiveness rates of 70-85% across different patient populations. This branded sildenafil treatment works by blocking the PDE5 enzyme, which may increase blood flow to the penis when combined with sexual arousal. The medication typically begins working within 30-60 minutes, with effects potentially lasting 4-6 hours, though this doesn't mean erections persist throughout this period.

Comparing Viagra and Generic Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil, allowing patients to choose their preferred option. Both contain the same active ingredient - sildenafil citrate - and demonstrate identical effectiveness rates. The main difference lies in cost, with generic sildenafil typically offering better value whilst maintaining the same clinical benefits. Patients can select between branded or generic options during the checkout process following their clinical assessment.

Dosage Options and Treatment Personalisation

Viagra and sildenafil are available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, which may be adjusted based on effectiveness and tolerability. The maximum recommended dose is 100mg once per 24-hour period. Taking the medication 30-60 minutes before anticipated sexual activity typically provides optimal results, though fatty meals may delay onset of action.

Factors Affecting Treatment Effectiveness

Several factors may influence how well Viagra works for individual patients. Age, underlying health conditions, current medications, and psychological factors can all impact effectiveness rates. Men with diabetes, cardiovascular conditions, or those taking multiple medications may experience different response rates. This is why clinical assessment by UK-licensed prescribers helps determine the most suitable treatment approach.

Safety Considerations and Eligibility

Viagra requires prescription following online consultation to ensure patient safety and suitability. The medication isn't appropriate for men taking nitrates, those with severe heart conditions, or recent stroke/heart attack history. Drug interactions, particularly with blood pressure medications and alpha-blockers, require careful evaluation. EverydayMeds' clinical assessment process helps identify any contraindications before prescribing.

Getting Started with ED Treatment

Men considering Viagra can begin with an online consultation through EverydayMeds' platform. The assessment includes questions about medical history, current medications, and cardiovascular health. Once approved by a UK-licensed prescriber, patients can choose between branded Viagra or generic sildenafil based on their preferences and budget considerations. Discreet delivery ensures 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.
