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 Quickly Does Viagra Take Effect?

Viagra typically begins working within 30-60 minutes after taking the tablet. The active ingredient sildenafil citrate requires time to be absorbed into your bloodstream before it can effectively increase blood flow to help achieve and maintain an erection during sexual arousal. Peak effectiveness usually occurs around 1-2 hours after taking the medication.

Getting Started with EverydayMeds Online Consultation

Our streamlined online consultation process makes accessing ED treatment straightforward and confidential. Simply complete our comprehensive medical questionnaire, which covers your medical history, current medications, and symptoms. Our UK-licensed clinicians will review your assessment within hours, not days.

During checkout, you can choose between branded Viagra or the generic sildenafil - both contain the same active ingredient but sildenafil offers a more cost-effective option whilst maintaining the same clinical effectiveness.

What to Expect During Your Assessment

Our clinical team evaluates several factors to determine your suitability for sildenafil treatment. This includes checking for potential contraindications such as heart conditions, current use of nitrate medications, or blood pressure concerns. The consultation also considers any other medications you're taking to avoid dangerous interactions.

If approved, your prescription can be dispatched the same day with next-day delivery options available across the UK. All packaging is completely discreet with no indication of contents.

Factors Affecting Viagra's Onset Time

Several factors can influence how quickly Viagra works for you. Taking the medication on an empty stomach typically results in faster absorption, whilst fatty meals can delay the onset by 30-60 minutes. Alcohol consumption may also slow absorption and reduce effectiveness.

Age and overall health can impact how quickly you metabolise the medication. Some men find that Viagra works more quickly after taking it regularly, though you should never exceed one tablet in 24 hours.

Dosage Options and Effectiveness

EverydayMeds offers Viagra and sildenafil in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, which can be adjusted based on effectiveness and tolerance. Our clinicians will recommend the most appropriate starting dose based on your consultation responses.

The medication's effects can last 4-6 hours, though this doesn't mean you'll have an erection for this duration. You'll still need sexual arousal for the medication to be effective, as it works by enhancing your natural response rather than causing automatic erections.

Ongoing Support and Prescription Management

After your initial consultation, managing your prescription is simple through your secure patient portal. You can request repeat prescriptions, adjust dosages with clinical approval, or ask questions about your treatment. Our pharmacy team is available to provide guidance on timing, storage, and any concerns about your medication.

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.
