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 Treatment Effectiveness Issues

Why Viagra May Not Work Initially

When Viagra (sildenafil) doesn't produce the expected results, it's important to understand that this is relatively common. Studies suggest that approximately 30-35% of men don't respond adequately to their first attempt with sildenafil treatment. This doesn't mean the medication won't work for you - often, adjustments to timing, dosage, or approach can significantly improve effectiveness.

Common Factors Affecting Effectiveness

Several factors can impact how well Viagra or generic sildenafil works. Timing plays a crucial role - taking the medication too close to a large or fatty meal can delay absorption and reduce effectiveness. The medication typically works best when taken 30-60 minutes before sexual activity on a relatively empty stomach.

Psychological factors such as anxiety, stress, or performance pressure can also interfere with treatment effectiveness. Since sildenafil requires sexual arousal to work properly, mental barriers can significantly impact results. Additionally, alcohol consumption can reduce blood flow and interfere with the medication's action.

Medical Conditions That May Reduce Response

Certain underlying health conditions can affect how well erectile dysfunction treatments work. Diabetes, particularly when poorly controlled, can damage blood vessels and nerves, potentially reducing treatment response. Cardiovascular conditions that affect blood flow may also impact effectiveness.

Severe erectile dysfunction, often related to significant vascular damage or neurological conditions, may require higher doses or alternative treatment approaches. Low testosterone levels can also contribute to reduced effectiveness, as can certain medications for depression, high blood pressure, or prostate conditions.

Optimising Your Treatment Approach

If your initial experience with Viagra hasn't been successful, several adjustments might help. Dosage optimisation is often key - while most men start with 50mg, some may benefit from increasing to 100mg or, conversely, may respond better to 25mg with fewer side effects.

Timing adjustments can also make a significant difference. Some men find taking the medication 30 minutes before activity works better, while others benefit from taking it up to 2 hours beforehand. Avoiding large meals and excessive alcohol before taking the medication often improves results.

When to Consider Alternatives

If Viagra or sildenafil continues to be ineffective after proper dosage and timing adjustments, other PDE5 inhibitors might be worth considering. Different medications in this class can have varying effectiveness for individual patients. Your prescriber might recommend trying alternatives like tadalafil, which has a different duration of action.

For men who don't respond to oral medications, other treatment options may be available through specialist services. These might include vacuum devices, injection therapies, or other medical interventions, though these would require referral to appropriate specialist services.

Getting the Right Support

At EverydayMeds, our clinical team can help assess why your treatment might not be working optimally. We offer both branded Viagra and generic sildenafil, allowing you to choose the option that best suits your needs and budget. Our prescribers can review your medical history, current medications, and lifestyle factors to help optimise your treatment approach.

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.
