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.

Meeting Prescription Requirements for Viagra Access

Understanding Viagra Prescription Requirements in the UK

Viagra remains a prescription-only medicine (POM) in the UK, meaning you cannot legally purchase it without first obtaining a valid prescription from a qualified healthcare professional. This prescription requirement exists because Viagra can interact dangerously with certain medications, particularly nitrates used for heart conditions, and may not be suitable for men with specific health conditions. The prescription process ensures your safety whilst providing access to effective treatment that typically works within 30-60 minutes of taking.

At EverydayMeds, our online consultation process streamlines prescription requirements whilst maintaining full clinical oversight. You'll complete a comprehensive medical questionnaire reviewed by UK-licensed prescribers who assess your suitability for Viagra or generic sildenafil treatment. This remote assessment meets all regulatory requirements whilst offering convenience and discretion.

Clinical Assessment Requirements for Viagra Prescriptions

The prescription process for Viagra involves a thorough clinical assessment covering several key areas. Prescribers must evaluate your cardiovascular health, as sexual activity places demands on your heart, and Viagra affects blood pressure. You'll need to disclose current medications, particularly any nitrates, alpha-blockers, or blood pressure medications that could interact with sildenafil. Previous medical history, including heart attacks, strokes, liver problems, or eye conditions, forms part of the assessment.

Your age and overall health status influence prescription decisions. Whilst Viagra is licensed for men aged 18 and over, prescribers may recommend starting with lower doses (25mg) for older men or those with underlying health conditions. The assessment also considers whether you've previously used erectile dysfunction treatments and any side effects experienced. This comprehensive evaluation ensures Viagra's 30-60 minute onset time delivers safe, effective results.

Online Prescription Process at EverydayMeds

EverydayMeds has developed a secure online prescription service that meets all UK regulatory requirements whilst providing convenient access to Viagra. The process begins with our detailed medical questionnaire, covering your health history, current medications, and erectile dysfunction symptoms. This information is reviewed by GMC-registered prescribers who specialise in men's health conditions.

Once approved, you can choose between branded Viagra or generic sildenafil at checkout - both contain identical active ingredients and work within the same 30-60 minute timeframe. Many patients choose generic sildenafil due to significant cost savings whilst maintaining the same clinical effectiveness. Your prescription is then dispensed by our GPhC-registered pharmacy and prepared for discreet delivery.

Documentation and Legal Requirements

Valid Viagra prescriptions must include specific information to meet UK legal requirements. The prescription must specify the exact dosage (typically 25mg, 50mg, or 100mg), quantity supplied, and clear patient identification details. Prescribers must also maintain records of the clinical assessment and ongoing monitoring requirements.

EverydayMeds maintains full audit trails of all prescriptions, ensuring compliance with MHRA regulations and GPhC standards. Your prescription remains valid for six months from the date of issue, allowing repeat orders without repeating the full consultation process, provided your health circumstances remain unchanged. This convenience means you can reorder when needed, knowing your Viagra will continue working within its established 30-60 minute timeframe.

Safety Checks and Contraindication Screening

Prescription requirements include mandatory safety screening for conditions that could make Viagra dangerous. Men taking nitrate medications for angina or heart conditions cannot safely use Viagra due to potentially fatal blood pressure drops. The prescription process identifies these contraindications through detailed medication reviews and health history assessment.

Other safety considerations include severe liver or kidney problems, recent heart attacks or strokes, certain eye conditions, and blood pressure abnormalities. These screening requirements protect your safety whilst ensuring Viagra can work effectively within its normal timeframe. EverydayMeds' prescribers are trained to identify these risk factors and recommend alternative treatments when appropriate.

Ongoing Monitoring and Prescription Reviews

Viagra prescriptions require periodic review to ensure continued safety and effectiveness. Prescribers assess whether the medication continues working as expected within its 30-60 minute onset time, evaluate any side effects, and review changes in your health status or other medications. These reviews typically occur every 6-12 months but may be more frequent if you have underlying health conditions.

EverydayMeds facilitates ongoing monitoring through follow-up questionnaires and clinical reviews. This ensures your prescription remains appropriate and effective whilst maintaining the convenience of online access. If your health circumstances change or you start new medications, additional clinical assessment may be required before your next Viagra prescription can be issued.

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.
