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.

Viagra Safety: Clinical Evidence and Considerations

Understanding Viagra's Safety Profile

Viagra has demonstrated a well-established safety profile since its approval for erectile dysfunction treatment. The medication works as a PDE5 inhibitor, increasing blood flow to the penis when sexually aroused. Clinical studies involving thousands of men have confirmed its effectiveness and identified its side effect profile, making it one of the most researched ED treatments available.

Prescription Viagra vs Viagra Connect: Key Differences

Prescription Viagra offers complete dosage flexibility, allowing clinicians to prescribe 25mg, 50mg, or 100mg tablets based on individual needs and tolerability. This personalised approach may enhance both effectiveness and safety. Viagra Connect, available over-the-counter, provides convenient access but restricts users to a fixed 50mg dose without professional medical supervision.

The prescription route includes comprehensive medical assessment, evaluating cardiovascular health, current medications, and medical history. This thorough evaluation helps identify potential contraindications and drug interactions that could compromise safety.

Generic Sildenafil: Same Safety, Better Value

Generic sildenafil contains the identical active ingredient as branded Viagra, ensuring equivalent safety and effectiveness. The manufacturing standards for generic medicines in the UK are rigorously regulated, requiring bioequivalence studies to demonstrate identical absorption and action compared to the original branded product.

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout, providing flexibility to balance personal preferences with cost considerations. Many patients find generic sildenafil offers excellent value whilst maintaining the same therapeutic benefits.

Who Should Avoid Viagra?

Certain medical conditions and medications create contraindications for Viagra use. Men taking nitrates for chest pain, including GTN spray or isosorbide tablets, must not use Viagra due to dangerous blood pressure interactions. Recent heart attack or stroke, severe liver impairment, and very low blood pressure also preclude safe usage.

Professional medical assessment identifies these risk factors before prescribing, enhancing safety compared to self-medication approaches. UK-licensed clinicians evaluate each patient's individual circumstances to ensure appropriate treatment selection.

Common Side Effects and Management

Most men tolerate Viagra well, though some may experience mild side effects including headache, facial flushing, indigestion, or nasal congestion. These effects typically resolve naturally and often diminish with continued use. Serious side effects remain rare but require immediate medical attention, including prolonged erections lasting over four hours or sudden vision changes.

Starting with lower doses and avoiding alcohol or fatty meals can minimise side effect likelihood whilst maintaining effectiveness. Professional guidance helps optimise dosing for individual tolerance levels.

Professional Assessment at EverydayMeds

Our comprehensive consultation process evaluates your medical history, current medications, and cardiovascular health to ensure safe Viagra usage. UK-licensed prescribers review each application individually, providing personalised treatment recommendations and dosage guidance.

This thorough assessment process, combined with ongoing support and the option to choose between branded and generic formulations, ensures you receive safe, effective ED treatment tailored to your individual needs and circumstances.

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.
