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.

Professional Monitoring and Treatment Assessment

Initial Treatment Monitoring Period

When starting Viagra or sildenafil treatment, healthcare professionals typically recommend monitoring effectiveness over 4-6 attempts before making dose adjustments. The standard starting dose of 50mg may be increased to 100mg or reduced to 25mg based on individual response and tolerability. EverydayMeds provides both branded Viagra and generic sildenafil options, allowing patients flexibility in their treatment choice whilst maintaining consistent monitoring protocols.

Effectiveness Tracking Parameters

Effective monitoring involves assessing several key factors including onset time, duration of effect, quality of erections achieved, and any side effects experienced. Patients should note whether the medication works within the expected 30-60 minute timeframe and whether effects last the typical 4-6 hours. Food intake, particularly fatty meals, can significantly impact absorption and should be documented when tracking treatment response.

Side Effect Monitoring

Common side effects such as headaches, facial flushing, nasal congestion, or indigestion should be recorded for severity and duration. Most side effects are mild and temporary, but any persistent or concerning symptoms warrant immediate consultation with the prescribing clinician. Cardiovascular monitoring is particularly important for patients with underlying heart conditions or those taking multiple medications.

Regular Clinical Reviews

NHS guidelines recommend regular reviews every 3-6 months to assess ongoing treatment effectiveness and safety. These consultations evaluate whether the current dose remains appropriate, discuss any changes in health status or medications, and ensure continued suitability for PDE5 inhibitor therapy. EverydayMeds facilitates these reviews through qualified UK-licensed prescribers, ensuring patients receive comprehensive ongoing care.

Treatment Optimisation Strategies

If initial treatment proves less effective than expected, several optimisation strategies may be considered. These include dose adjustment, timing modifications, lifestyle factors review, or consideration of underlying causes that may affect treatment response. The choice between branded Viagra and generic sildenafil typically does not affect monitoring requirements, as both contain the same active ingredient and require identical clinical oversight.

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.
