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.

Online Prescription Process for Viagra

How to Access Viagra Through EverydayMeds

Getting Viagra online through EverydayMeds is straightforward and confidential. Our clinical team provides prescription-only erectile dysfunction treatments following a comprehensive online assessment. You'll complete a detailed medical questionnaire reviewed by UK-licensed prescribers who ensure the treatment is suitable for your health profile.

During checkout, you can choose between branded Viagra or generic sildenafil - both contain the same active ingredient but sildenafil offers a more cost-effective alternative. Our prescribers evaluate your cardiovascular health, current medications, and medical history to determine appropriate dosing, typically starting with 50mg tablets.

Understanding Viagra's Duration and Effectiveness

Viagra's effects typically last 4-6 hours, meaning the medication remains active in your system during this window. However, this doesn't mean you'll maintain an erection for hours - sexual stimulation is still required for the medication to work effectively. Most men find Viagra takes 30-60 minutes to become effective, with peak effects occurring around 1-2 hours after taking.

The duration can vary based on individual factors including age, overall health, alcohol consumption, and food intake. Fatty meals may delay Viagra's onset, so taking it on an empty stomach often produces faster results. Remember, you should only take one dose per 24-hour period, regardless of whether you choose branded Viagra or generic sildenafil.

Prescription Requirements and Safety Considerations

Viagra requires a prescription because it can interact dangerously with certain medications, particularly nitrates used for chest pain. Our clinical assessment ensures you're not taking contraindicated medications and that your cardiovascular system can safely handle the increased blood flow that Viagra promotes.

Men with severe heart conditions, recent strokes, very low blood pressure, or severe liver problems may not be suitable candidates. Our prescribers also review any medications you're currently taking, as certain drugs can affect how long Viagra lasts or increase the risk of side effects.

Discreet Service and Delivery Options

EverydayMeds prioritises your privacy throughout the prescription process. All consultations are conducted confidentially online, and medications arrive in unmarked packaging. We offer next-day delivery options so you can access your prescribed treatment quickly and discreetly.

Whether you choose branded Viagra or generic sildenafil, you'll receive the same professional service and clinical oversight. Our UK-licensed prescribers are available to answer questions about dosing, timing, or any concerns about how long the effects should last for your individual 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.
