Understanding whether you're a suitable candidate involves evaluating your health status, current medications, and medical history.

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 Assessment for Viagra Safety

Medical Eligibility Requirements

Viagra is safe when prescribed to appropriate candidates following thorough clinical assessment. Our UK-licensed prescribers evaluate several key factors to determine suitability. Adult men experiencing erectile dysfunction represent the primary candidate group, though not all men qualify for treatment. Your cardiovascular health, current medications, and medical history significantly influence whether Viagra represents a safe option.

Patients must complete a comprehensive medical questionnaire covering heart health, blood pressure status, and all current medications. This assessment ensures Viagra is safe for your specific circumstances whilst identifying any potential contraindications that might make treatment unsuitable.

Cardiovascular Considerations

Viagra is safe for men with stable cardiovascular health, though certain heart conditions may preclude treatment. Recent heart attack or stroke within six months typically contraindicate Viagra use. Similarly, severe heart disease, uncontrolled high blood pressure, or very low blood pressure may make treatment inappropriate.

Men taking nitrate medications for chest pain cannot safely use Viagra due to dangerous blood pressure interactions. This includes GTN sprays, isosorbide tablets, and similar cardiac medications. Your prescriber will carefully review all medications to ensure Viagra is safe for concurrent use.

Age and General Health Factors

Viagra is safe across various age groups, though older patients may require dose adjustments. Men over 65 often start with lower 25mg doses rather than the standard 50mg starting dose. This cautious approach ensures Viagra remains safe whilst providing effective results.

Liver or kidney problems may affect how your body processes Viagra, potentially requiring dose modifications. Severe liver impairment may contraindicate treatment entirely. Your prescriber will evaluate these factors to determine appropriate dosing or alternative treatments.

Medication Interactions and Safety

Viagra is safe when not combined with certain medications. Beyond nitrates, some blood pressure medications, particularly alpha-blockers, may interact with Viagra. Riociguat, used for pulmonary hypertension, represents another dangerous combination.

Recreational drugs containing nitrates or "poppers" must be avoided completely when using Viagra. Your prescriber will provide comprehensive guidance on medication interactions to ensure Viagra remains safe throughout treatment.

Choosing Between Viagra and Generic Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil, allowing patients to choose based on preference and budget. Both contain identical active ingredients and undergo the same safety assessments. Generic sildenafil provides a more affordable option whilst maintaining equivalent safety and efficacy profiles.

Many patients find generic sildenafil offers excellent value without compromising safety or effectiveness. Your consultation will explore both options, ensuring you receive appropriate treatment that fits your clinical needs and personal preferences whilst maintaining the highest safety standards.

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.
