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

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

Understanding Viagra Prescription Criteria for Men

Essential Medical Requirements for Viagra Prescription

To obtain a Viagra prescription as a male patient in the UK, you must meet specific clinical criteria established by regulatory authorities. The primary requirement is being an adult male aged 18 or over experiencing erectile dysfunction symptoms. Our UK-licensed prescribers conduct thorough assessments to ensure Viagra is medically appropriate for your individual circumstances.

The prescription process involves evaluating your cardiovascular health, as Viagra affects blood flow and can interact with heart medications. Men taking nitrate medications for chest pain cannot safely use Viagra due to dangerous blood pressure interactions. Similarly, those with severe heart conditions, recent strokes, or very low blood pressure may not be suitable candidates for treatment.

Clinical Assessment Process at EverydayMeds

Our online consultation system guides you through a comprehensive medical questionnaire covering your erectile dysfunction symptoms, general health, and current medications. This information allows our GMC-registered prescribers to assess your eligibility accurately. The assessment typically takes 5-10 minutes to complete and covers essential safety questions about your cardiovascular health and medication history.

Honest completion of the clinical questionnaire is crucial for your safety. Our prescribers need accurate information about any heart conditions, blood pressure medications, or recreational drug use to make appropriate prescribing decisions. This includes disclosing use of recreational substances like "poppers" which contain nitrates and can cause dangerous interactions with Viagra.

Age and Health Considerations

Viagra prescription requirements include minimum age restrictions, with treatment only available to men aged 18 and over. There is no upper age limit, but older patients may require additional cardiovascular assessment due to increased risk of heart conditions. Our prescribers consider your overall health status, not just your age, when determining suitability for treatment.

Men with diabetes, high blood pressure, or other chronic conditions can often still access Viagra treatment, provided these conditions are well-controlled and don't contraindicate use. The key is ensuring your cardiovascular system can safely handle the medication's effects on blood flow and the physical demands of sexual activity.

Medication Interactions and Contraindications

Prescription requirements include detailed review of your current medications to identify potential interactions. Viagra is absolutely contraindicated with nitrate medications used for angina, including GTN spray and isosorbide tablets. Taking these medications together can cause life-threatening blood pressure drops.

Alpha-blocker medications for prostate problems may require dose adjustments or careful monitoring when combined with Viagra. Our prescribers review all your medications, including over-the-counter supplements, to ensure safe prescribing. Blood pressure medications, certain antibiotics, and antifungal treatments can affect how Viagra works in your system.

Choosing Between Branded and Generic Options

Once you meet the prescription requirements, EverydayMeds offers flexibility in choosing between branded Viagra and generic sildenafil. Both contain the same active ingredient and work identically, with the main difference being cost. Our prescribers explain both options, allowing you to make an informed choice at checkout based on your preferences and budget.

The prescription requirements are identical whether you choose branded Viagra or generic sildenafil. Both require the same clinical assessment and safety checks. Some men prefer the branded option for psychological reasons, whilst others choose the generic version for cost savings without compromising on quality or effectiveness.

Dosage Determination and Prescription Flexibility

Meeting prescription requirements allows access to different Viagra dosages: 25mg, 50mg, and 100mg tablets. Our prescribers typically start with 50mg for most men, adjusting based on effectiveness and tolerability. The prescription process includes discussing your specific needs and any previous experience with erectile dysfunction treatments.

Prescription flexibility means you can request dose adjustments through follow-up consultations. If the initial prescribed dose isn't optimal, our clinical team can modify your prescription accordingly. This personalised approach ensures you receive the most appropriate treatment whilst maintaining safety standards throughout your care.

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.
