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.

How Long Does Viagra Actually Last?

Viagra's effects typically last between 4-6 hours after taking the tablet, though individual responses may vary. This timeframe refers to how long the medication remains effective in your system, not the duration of an erection. The medication begins working within 30-60 minutes of taking it, reaching peak effectiveness around 1-2 hours. During this window, you may find it easier to achieve and maintain erections when sexually aroused.

Accessing Viagra Through EverydayMeds

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

Prescription Requirements and Medical Assessment

UK regulations require a valid prescription for Viagra, as it's classified as a prescription-only medicine (POM). Our clinicians evaluate several factors including cardiovascular health, existing medical conditions, and potential drug interactions. Men taking nitrate medications, those with severe heart conditions, or recent stroke history typically cannot use Viagra due to safety concerns. The assessment also considers your blood pressure, liver function, and any medications that might interact dangerously with sildenafil.

Branded Viagra vs Generic Sildenafil Options

EverydayMeds offers both branded Viagra and generic sildenafil at checkout, allowing you to choose based on preference and budget. Both contain the same active ingredient (sildenafil citrate) and work identically, with generic versions offering significant cost savings. The duration of effectiveness remains the same regardless of whether you choose branded or generic options. Available strengths include 25mg, 50mg, and 100mg tablets, with 50mg being the typical starting dose.

Factors Affecting Viagra's Duration

Several factors influence how long Viagra lasts in your system. Age, overall health, and metabolism affect the medication's duration and effectiveness. Food intake, particularly fatty meals, can delay onset but doesn't significantly impact overall duration. Alcohol consumption may reduce effectiveness and should be limited when using Viagra. Individual response varies, with some men experiencing effects for the full 6-hour window whilst others find effectiveness diminishes after 4 hours.

Safety Considerations and Ongoing Support

Taking Viagra requires adherence to prescribed dosing guidelines - never exceed one tablet in 24 hours. Common side effects include headache, facial flushing, and mild indigestion, typically resolving within a few hours. Serious side effects are rare but require immediate medical attention, including prolonged erections lasting over 4 hours or sudden vision changes. EverydayMeds provides ongoing clinical support, allowing you to discuss any concerns with our medical team and adjust treatment as needed.

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.
