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.

Get Viagra Online Through Clinical Assessment

How to Access Viagra Through Online Consultation

Getting Viagra or sildenafil online through EverydayMeds is straightforward and confidential. Our online consultation process connects you with UK-licensed prescribers who can assess your suitability for erectile dysfunction treatment. You'll complete a comprehensive medical questionnaire covering your health history, current medications, and symptoms. This clinical assessment ensures the medication is safe and appropriate for your individual circumstances.

Understanding How Long Viagra Works

Viagra typically remains effective for 4-6 hours after taking, though individual response times may vary. The medication begins working within 30-60 minutes of taking on an empty stomach, with peak effectiveness usually occurring 1-2 hours after administration. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to work effectively.

Several factors can influence how long Viagra works for you, including your age, overall health, other medications, and whether you've eaten recently. Fatty meals may delay the onset of action, whilst alcohol can reduce effectiveness. Your prescriber will provide personalised guidance about timing and expectations during your online consultation.

Branded Viagra vs Generic Sildenafil Options

EverydayMeds offers both branded Viagra and generic sildenafil, allowing you to choose the option that best suits your preferences and budget. Both medications contain the same active ingredient - sildenafil citrate - and work identically in your body. Generic sildenafil provides the same clinical effectiveness as branded Viagra but at a lower cost, making treatment more accessible.

During your online assessment, you can discuss with your prescriber which option might be most suitable. Whether you choose branded Viagra or generic sildenafil, both are available in 25mg, 50mg, and 100mg strengths. Most men start with a 50mg dose, which can be adjusted based on effectiveness and any side effects experienced.

What to Expect During Your Online Consultation

Our online consultation process is designed to be thorough yet convenient. You'll answer detailed questions about your medical history, current health conditions, and any medications you're taking. The assessment covers cardiovascular health, blood pressure, and factors that might affect your suitability for sildenafil-based treatments.

UK-licensed clinicians review every consultation personally, ensuring you receive appropriate medical care. If approved, your prescription is processed by our registered UK pharmacy and dispatched in discreet packaging. The entire process typically takes 24-48 hours from consultation to delivery, making it a convenient alternative to traditional GP appointments.

Safety Considerations and Medical Supervision

Viagra and sildenafil are prescription-only medicines that require proper medical supervision. Our online consultation process identifies any potential contraindications or drug interactions that could make treatment unsuitable. Men taking nitrate medications, those with severe heart conditions, or certain other medical circumstances may not be suitable candidates for these treatments.

Regular monitoring through follow-up consultations helps ensure your treatment remains safe and effective. Our pharmacists are available to answer questions about your medication and provide ongoing support throughout your treatment journey.

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.
