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 Monitoring and Safety Protocols for Viagra

Pre-Treatment Safety Assessment

Before prescribing Viagra, UK-licensed prescribers conduct comprehensive clinical assessments to determine patient suitability. This evaluation includes cardiovascular health screening, current medication review, and medical history analysis. Patients with heart conditions, those taking nitrates, or individuals with severe liver impairment may not be suitable candidates. EverydayMeds ensures all patients complete thorough consultations before accessing treatment, with both branded Viagra and generic sildenafil options available following approval.

Ongoing Monitoring Requirements

Effective Viagra treatment requires regular monitoring to track therapeutic response and identify potential side effects. Healthcare professionals assess treatment effectiveness typically within 4-6 weeks of starting therapy, evaluating whether the prescribed dose achieves desired results without adverse effects. Patients may require dose adjustments from the standard 50mg starting dose to 25mg or 100mg based on individual response and tolerability.

Safety Protocols and Risk Management

Viagra safety protocols include strict adherence to maximum dosing guidelines of one tablet per 24-hour period and careful monitoring for drug interactions. Common side effects such as headaches, facial flushing, and nasal congestion are generally mild and temporary. However, serious adverse effects including sudden vision changes, prolonged erections exceeding four hours, or chest pain require immediate medical attention. Regular follow-up consultations allow healthcare providers to adjust treatment plans and ensure continued safety.

Contraindication Screening

Comprehensive contraindication screening prevents potentially dangerous situations. Patients taking nitrates for heart conditions cannot safely use Viagra due to severe blood pressure interactions. Recent heart attacks, strokes, or severe hypotension also contraindicate use. Licensed prescribers review all current medications and health conditions to identify potential conflicts before prescribing either branded Viagra or generic sildenafil alternatives.

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.
