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

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

How Long Does Viagra Last? Complete UK Guide

How to Buy Viagra Online in the UK

Purchasing Viagra online through EverydayMeds is straightforward and regulated. Start by completing our confidential online consultation form, which takes just a few minutes. A UK-licensed prescriber will review your medical history and current medications to determine if Viagra is suitable for you. Once approved, you can choose between branded Viagra or generic sildenafil at checkout - both contain the same active ingredient but generic sildenafil offers a more cost-effective option.

How Long Does Viagra Last in Your System?

Viagra typically remains effective for 4-6 hours after taking the tablet. This doesn't mean you'll have an erection for this entire duration - you'll still need sexual stimulation for the medication to work. The effects usually begin within 30-60 minutes of taking the tablet on an empty stomach. Fatty meals can delay the onset, so consider timing your dose accordingly. Most men find the strongest effects occur within the first 2-3 hours.

Factors Affecting Viagra Duration

Several factors can influence how long Viagra lasts in your system. Age plays a role - men over 65 may experience longer-lasting effects due to slower metabolism. Your overall health, particularly liver and kidney function, affects how quickly your body processes the medication. Alcohol consumption can reduce effectiveness and shouldn't be consumed excessively when taking Viagra. The dosage prescribed (25mg, 50mg, or 100mg) also impacts duration and intensity of effects.

Online Consultation Process

Our online consultation ensures you receive appropriate treatment safely. You'll answer questions about your medical history, current medications, and symptoms of erectile dysfunction. UK-licensed prescribers check for contraindications, particularly with nitrate medications which can cause dangerous interactions. The consultation covers cardiovascular health, as Viagra affects blood flow. Once approved, your prescription is fulfilled by our registered UK pharmacy.

Viagra vs Generic Sildenafil Options

EverydayMeds offers both branded Viagra and generic sildenafil to suit different preferences and budgets. Both medications contain identical active ingredients and work in exactly the same way. Generic sildenafil provides significant cost savings while maintaining the same effectiveness and safety profile. You can discuss which option suits your needs during the consultation process. Both are available in 25mg, 50mg, and 100mg strengths.

Dosage and Usage Guidelines

The standard starting dose is 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if 50mg proves insufficient. Never exceed one tablet in any 24-hour period. Take the tablet with water and avoid large, fatty meals beforehand. Plan intimate activity within the 4-6 hour effectiveness window for optimal results.

Safety Considerations and Side Effects

Common side effects include headaches, facial flushing, and nasal congestion, which typically resolve as the medication leaves your system. Viagra can cause a temporary drop in blood pressure, so avoid combining with alcohol or other blood pressure medications without medical advice. Rare but serious side effects require immediate medical attention, including prolonged erections lasting over 4 hours or sudden vision changes. Our prescribers will assess your suitability based on your medical history.

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.
