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.

Clinical Effectiveness Data for Viagra and Sildenafil

Proven Effectiveness Rates Across Clinical Studies

Extensive clinical trials have established that sildenafil-based treatments, including both Viagra and generic alternatives, demonstrate effectiveness rates between 70-85% in men with erectile dysfunction. These studies involved thousands of participants across various age groups and underlying health conditions. The effectiveness rate refers to the ability to achieve and maintain an erection sufficient for sexual activity when sexually aroused.

Factors Influencing Treatment Success

Several factors may influence how well sildenafil works for individual patients. Age, underlying health conditions such as diabetes or cardiovascular disease, psychological factors, and concurrent medications can all impact effectiveness. Patients with diabetes may experience slightly lower success rates, whilst those with primarily psychological causes of ED often see higher effectiveness rates. The presence of adequate sexual stimulation remains essential, as sildenafil does not cause automatic erections.

Comparing Branded Viagra vs Generic Sildenafil

Both branded Viagra and generic sildenafil contain identical active ingredients and demonstrate equivalent clinical effectiveness. The main difference lies in cost, with generic sildenafil offering substantial savings whilst maintaining the same therapeutic benefits. EverydayMeds provides both options, allowing patients to choose based on their preferences and budget considerations during the checkout process.

Dosage Optimisation for Maximum Effectiveness

The starting dose of 50mg proves effective for most men, though some may benefit from dose adjustment. Clinical assessment may determine whether 25mg provides sufficient effect with fewer side effects, or whether 100mg offers improved effectiveness. Taking the medication 30-60 minutes before sexual activity on an empty stomach typically provides optimal results. Heavy or fatty meals may delay the onset of action.

Timeline of Effects and Duration

Sildenafil typically begins working within 30-60 minutes of administration, with peak effectiveness occurring around 1-2 hours after taking the medication. The effects may last 4-6 hours, though this refers to the window during which the medication can be effective when combined with sexual arousal, not the duration of an erection. Individual response times may vary based on metabolism, age, and other health factors.

Realistic Expectations and Success Rates

Whilst clinical studies demonstrate high effectiveness rates, individual results may vary. Some men may need to try different doses or explore alternative treatment approaches if sildenafil does not provide adequate results. Psychological factors, relationship dynamics, and lifestyle factors all contribute to treatment success. Combining medication with lifestyle improvements such as regular exercise, stress management, and addressing underlying health conditions may enhance effectiveness.

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.
