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 Our Viagra Assessment Works

Getting started with Viagra through EverydayMeds is straightforward and completely confidential. Our online consultation process is designed to assess your suitability for ED treatment safely and efficiently. You'll complete a comprehensive medical questionnaire covering your symptoms, medical history, current medications, and cardiovascular health. This information is reviewed by our UK-licensed prescribers who determine whether Viagra or Sildenafil is appropriate for your individual circumstances.

Understanding Viagra Duration and Effectiveness

Viagra typically remains active in your system for 4-6 hours after taking a dose. However, it's important to understand that this doesn't mean you'll maintain an erection for this entire period. The medication works by improving blood flow to the penis when you're sexually aroused, so you'll still need sexual stimulation for it to be effective. Most men find Viagra starts working within 30-60 minutes of taking it, with peak effectiveness usually occurring around 1-2 hours after consumption.

Choosing Between Viagra and Sildenafil

At EverydayMeds, we offer both branded Viagra and generic Sildenafil at checkout, giving you the flexibility to choose based on your preferences and budget. Both contain the same active ingredient (sildenafil citrate) and work identically - the main difference is cost. Generic Sildenafil provides the same clinical benefits as branded Viagra but at a more affordable price point. Our prescribers can advise which option might be most suitable during your consultation.

Dosage Options and Personalisation

Viagra and Sildenafil are available in 25mg, 50mg, and 100mg strengths. Most men start with the 50mg dose, which can then be adjusted based on effectiveness and any side effects experienced. Your prescribed dosage will depend on factors including your medical history, current medications, and how you respond to treatment. Remember, you should never take more than one dose within 24 hours, and the medication should be taken approximately 30-60 minutes before sexual activity.

Who Can Access Viagra Treatment

Viagra is suitable for adult men over 18 experiencing erectile dysfunction. However, it's not appropriate for everyone. During our assessment, we'll check for any contraindications such as cardiovascular conditions, current medications that may interact dangerously with sildenafil, or other health factors that might make treatment unsuitable. Men taking nitrate medications (such as GTN spray) cannot safely use Viagra due to the risk of dangerous blood pressure drops.

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.
