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 Sildenafil Effectiveness and Success Rates

Clinical Evidence for Sildenafil Success Rates

Extensive clinical research demonstrates that sildenafil citrate achieves positive results in 70-85% of men with erectile dysfunction. These success rates vary based on underlying causes, with higher effectiveness observed in men with psychogenic ED compared to those with severe vascular conditions. The medication works by blocking the PDE5 enzyme, increasing blood flow to the penis when sexually stimulated.

Comparing Generic Sildenafil and Branded Viagra

Both generic sildenafil and branded Viagra contain identical active ingredients and deliver equivalent effectiveness rates. The primary difference lies in cost, with generic sildenafil typically offering significant savings whilst maintaining the same therapeutic benefits. EverydayMeds stocks both options, enabling patients to select their preferred choice during the ordering process based on personal preference and budget considerations.

Factors Influencing Treatment Success

Several factors can impact sildenafil's effectiveness rate. Men with diabetes, cardiovascular disease, or those taking certain medications may experience varying response rates. Age also plays a role, though sildenafil remains effective across different age groups. Lifestyle factors such as smoking, excessive alcohol consumption, and obesity can reduce effectiveness. Proper timing is crucial - taking sildenafil 30-60 minutes before sexual activity optimises results.

Dosage Optimisation for Maximum Effectiveness

Sildenafil is available in 25mg, 50mg, and 100mg strengths, with 50mg serving as the standard starting dose for most men. Clinical assessments help determine the optimal dosage based on individual response and tolerability. Some men may require dose adjustments to achieve maximum effectiveness whilst minimising potential side effects. The medication should not be taken more than once within 24 hours.

What to Expect from Treatment

When sildenafil works effectively, men typically notice improved ability to achieve and maintain erections suitable for sexual intercourse. The medication requires sexual stimulation to be effective and does not cause automatic erections. Effects begin within 30-60 minutes and can last up to 4-6 hours, providing a suitable window for sexual activity. Success rates may improve over the first few uses as men become more comfortable with the treatment.

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.
