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 Evidence: Sildenafil Effectiveness Rates

Understanding Sildenafil Success Rates

Clinical trials consistently demonstrate that sildenafil, whether as branded Viagra or generic sildenafil, achieves success rates between 70-85% for men with erectile dysfunction. These impressive statistics are based on extensive research involving thousands of participants across different age groups and underlying health conditions. The effectiveness rate can vary depending on the cause of erectile dysfunction, with psychological causes often showing higher success rates than those related to underlying medical conditions.

Comparing Branded Viagra vs Generic Sildenafil

Both branded Viagra and generic sildenafil contain the identical active ingredient - sildenafil citrate. This means they deliver equivalent effectiveness rates, with the primary difference being cost. Generic sildenafil typically costs significantly less than branded Viagra, making it an attractive option for many patients. At EverydayMeds, we provide both options during checkout, allowing you to choose based on your preference and budget whilst receiving the same clinical benefits.

Factors Affecting Treatment Success

Several factors influence sildenafil's effectiveness rate. Age plays a role, with younger men often experiencing higher success rates, though sildenafil remains effective across all adult age groups. Underlying health conditions such as diabetes, cardiovascular disease, or hormonal imbalances may impact effectiveness. Lifestyle factors including smoking, excessive alcohol consumption, and stress levels can also influence treatment outcomes. Additionally, taking sildenafil on an empty stomach typically improves absorption and effectiveness compared to taking it after heavy meals.

Optimising Treatment Effectiveness

To maximise sildenafil's effectiveness, several strategies can be employed. Taking the medication 30-60 minutes before sexual activity allows optimal absorption. Avoiding large, fatty meals beforehand prevents delayed onset. The standard starting dose is 50mg, which can be adjusted to 25mg or 100mg based on individual response and tolerability. It's important to remember that sexual stimulation is still required - sildenafil enhances natural physiological responses rather than creating automatic erections.

When Sildenafil May Not Be Effective

Whilst sildenafil shows high success rates, it may not be suitable for everyone. Men taking nitrate medications for heart conditions cannot safely use sildenafil due to dangerous drug interactions. Those with severe cardiovascular disease, recent heart attacks, or very low blood pressure require careful medical evaluation. Some men may not respond to sildenafil due to severe nerve damage, hormonal deficiencies, or severe vascular disease. In such cases, alternative treatments may be recommended following consultation with healthcare providers.

Prescription-Only Access and Safety

In the UK, sildenafil requires a prescription following consultation with a qualified prescriber. This ensures treatment suitability and safety for individual patients. EverydayMeds provides secure online consultations with UK-licensed prescribers who review medical history, current medications, and cardiovascular health before prescribing. This process protects patient safety whilst providing convenient access to effective ED treatment. Remember, you cannot legally buy prescription-strength sildenafil over the counter without proper medical assessment.

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.
