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 Last? Treatment Duration Guide

Getting Started: Online ED Treatment Access

If you're looking to change your erectile dysfunction prescription, EverydayMeds provides a straightforward online consultation service. Our UK-licensed prescribers can assess your suitability for Viagra or generic sildenafil through a comprehensive clinical questionnaire. The process typically takes 5-10 minutes, and approved prescriptions are usually processed within 24 hours.

Viagra Duration: What to Expect

Viagra typically remains effective for 4-6 hours after taking a dose. This doesn't mean you'll have an erection for this entire period - rather, it's the window during which the medication can help you achieve and maintain an erection when sexually aroused. The effects usually begin within 30-60 minutes of taking the tablet, though this can vary depending on individual factors and whether you've eaten recently.

The duration can be influenced by several factors including your age, overall health, dose taken, and other medications. Some men may find effects last slightly longer or shorter than the typical 4-6 hour window. Higher doses don't necessarily extend duration significantly but may provide more consistent effectiveness during this timeframe.

Dosage Options and Timing

Viagra is available in 25mg, 50mg, and 100mg tablets, with 50mg being the standard starting dose for most men. Your prescriber may recommend adjusting the dose based on effectiveness and any side effects experienced. The medication should be taken approximately 30-60 minutes before planned sexual activity, with a maximum of one dose in any 24-hour period.

Taking Viagra with a large or fatty meal may delay the onset of effects, potentially extending the time before you notice the medication working. For optimal timing, consider taking it on a relatively empty stomach or after a light meal.

Branded vs Generic Options

At EverydayMeds, you can choose between branded Viagra and generic sildenafil during checkout. Both contain the same active ingredient (sildenafil citrate) and work identically in terms of duration and effectiveness. The main difference is typically cost, with generic sildenafil offering a more economical option while providing the same therapeutic benefits.

Safety Considerations and Contraindications

Before switching to or starting Viagra, it's crucial to complete a thorough medical assessment. The medication isn't suitable for men taking nitrates for heart conditions, those with severe cardiovascular disease, or certain other medical conditions. Our online consultation covers your medical history, current medications, and overall health to ensure safe prescribing.

Ordering Process and Delivery

Once your online consultation is approved, you can complete your order with discreet packaging and next-day delivery options available. All medications are dispensed by our UK-registered pharmacy and delivered in plain, unmarked packaging to maintain your privacy.

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.
