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.

Getting Started: Your Viagra Timeline and Access Process

How Quickly Does Viagra Work?

Viagra typically starts working within 30-60 minutes of taking it, though this can vary between individuals. The medication reaches peak effectiveness around 1-2 hours after taking it, with effects lasting up to 4-6 hours. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective.

Factors That Affect Viagra's Onset Time

Several factors can influence how quickly Viagra begins working. Taking the medication on an empty stomach typically leads to faster absorption, whilst fatty meals may delay its effects by 30-60 minutes. Alcohol consumption can also slow absorption and may reduce effectiveness. Age and overall health status can influence onset time, with some men noticing effects within 15-30 minutes, whilst others may need the full hour.

Accessing Viagra Through EverydayMeds

Our online consultation process makes accessing ED treatment straightforward and discreet. You'll complete a comprehensive medical questionnaire that covers your symptoms, medical history, current medications, and cardiovascular health. This assessment is reviewed by one of our UK-licensed prescribers who will determine if Viagra or sildenafil is suitable for you.

Treatment Options Available

At checkout, you can choose between branded Viagra and generic sildenafil - both contain the same active ingredient (sildenafil citrate) and work identically. The main difference is cost, with generic sildenafil offering significant savings whilst maintaining the same effectiveness and safety profile. Both options are available in 25mg, 50mg, and 100mg strengths, with 50mg being the typical starting dose.

The Online Consultation Process

Our clinical assessment evaluates your suitability for ED treatment by reviewing potential contraindications and drug interactions. The prescriber will assess whether you're taking medications that could interact dangerously with sildenafil, such as nitrates for heart conditions. They'll also review your cardiovascular health, as ED medications can affect blood pressure.

Delivery and Ongoing Support

Once approved, your treatment is dispensed by our registered pharmacy and dispatched with next-day delivery in discreet packaging. We provide detailed information about proper usage, including timing recommendations and what to expect. Our clinical team remains available for ongoing support, and you can easily request repeat prescriptions through your online account when needed.

Maximising Treatment Effectiveness

To optimise Viagra's effectiveness, take it approximately one hour before planned sexual activity. Avoid large or fatty meals beforehand, and limit alcohol consumption. If the initial 50mg dose isn't effective, speak with our clinical team about adjusting to 25mg or 100mg. Remember that stress and anxiety can affect performance, so maintaining realistic expectations helps achieve the best outcomes.

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.
