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: Complete Online Assessment

Understanding Viagra Duration and Effects

Viagra typically provides effective treatment for erectile dysfunction for 4-6 hours after taking. This timeframe represents how long the medication remains active in your system, not the duration of any single erection. The active ingredient sildenafil citrate works by increasing blood flow when you're sexually aroused, with effects usually beginning 30-60 minutes after taking the tablet.

Start Your Online ED Assessment Today

EverydayMeds offers a straightforward online consultation process to access prescription ED treatments. Our UK-licensed prescribers conduct thorough clinical assessments to determine if Viagra or generic sildenafil is suitable for you. The online assessment evaluates your medical history, current medications, and cardiovascular health to ensure safe treatment.

During checkout, you can choose between branded Viagra or generic sildenafil - both contain the same active ingredient but generic options offer significant cost savings. Our clinical team will recommend the most appropriate dosage, typically starting with 50mg, which can be adjusted to 25mg or 100mg based on effectiveness and tolerability.

Factors Affecting How Long Viagra Lasts

Several factors influence Viagra's duration and effectiveness. Food intake, particularly fatty meals, can delay the medication's onset but doesn't significantly affect how long it lasts. Age, overall health, and other medications may also impact duration. Alcohol consumption can reduce effectiveness and should be limited when taking sildenafil-based treatments.

The medication works only when you're sexually stimulated - it doesn't cause automatic erections. Most men find the effects peak around 1-2 hours after taking Viagra, with effectiveness gradually declining over the 4-6 hour window.

Online Consultation Process

Our confidential online assessment takes approximately 5-10 minutes to complete. You'll answer questions about your medical history, current medications, and symptoms. UK-licensed prescribers review every consultation to ensure treatment safety and appropriateness.

If approved, your prescription is processed immediately and dispatched for next-day delivery in discreet packaging. We offer ongoing support through our clinical team, who can adjust your prescription if needed during follow-up consultations.

Dosage and Safety Information

Viagra is available in 25mg, 50mg, and 100mg strengths. Take only one tablet within any 24-hour period, approximately 30-60 minutes before sexual activity. The medication is not suitable for men taking nitrate medications, those with severe heart conditions, or recent stroke/heart attack history.

Common side effects may include headache, facial flushing, or indigestion, which typically resolve as the medication leaves your system. Serious side effects are rare but require immediate medical attention if experienced.

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.
