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 Viagra Online: Your Complete UK Guide

How Quickly Does Viagra Work?

Viagra generally becomes effective within 30-60 minutes of taking the tablet. However, several factors can influence this timing. Taking Viagra on an empty stomach may lead to faster absorption, whilst a heavy or fatty meal beforehand can delay the onset by up to an hour. The medication can remain effective for 4-6 hours, though this doesn't mean you'll have an erection for this entire period - sexual stimulation is still required for the medication to work.

Ordering Viagra Online Through EverydayMeds

Our streamlined online service makes accessing ED treatment straightforward and discreet. Start by completing our confidential medical questionnaire, which covers your medical history, current medications, and symptoms. A UK-licensed prescriber reviews your assessment, typically within 24 hours. If approved, you can choose between Viagra (the well-known branded version) or Sildenafil (the same active ingredient at a lower cost) during checkout.

Understanding Viagra Dosages and Timing

Viagra is available in 25mg, 50mg, and 100mg tablets, with 50mg being the standard starting dose for most men. Your prescriber may adjust this based on how well the medication works for you and any side effects experienced. Take your prescribed dose approximately one hour before sexual activity for optimal results. Remember, you should only take one dose within a 24-hour period.

Who Can Take Viagra Safely?

Viagra is suitable for adult men experiencing erectile dysfunction, but it's not appropriate for everyone. During our online consultation, our prescribers check for conditions that might make Viagra unsuitable, such as severe heart disease, low blood pressure, or if you're taking certain medications like nitrates. This medical review ensures you receive treatment that's both safe and effective for your individual circumstances.

Viagra vs Sildenafil: Making Your Choice

Both options contain the same active ingredient (sildenafil citrate) and work identically. Viagra is the original branded version manufactured by Pfizer, whilst Sildenafil is the generic alternative. Many patients find the generic version offers excellent value whilst maintaining the same effectiveness. Our service allows you to choose your preferred option at checkout, giving you flexibility over your treatment costs.

Maximising Treatment Effectiveness

To get the best results from your medication, take your tablet at the right time - usually 30-60 minutes before sexual activity. Avoid excessive alcohol, which can reduce effectiveness and increase the likelihood of side effects. If you're taking the medication for the first time, you might want to allow extra time to see how your body responds.

Ongoing Support and Reordering

Once approved for treatment, your prescription remains valid for six months, making reordering quick and convenient. Our customer service team is available if you have questions about your treatment or need to adjust your prescription. We also provide detailed patient information leaflets with every order, ensuring you have all the guidance needed for safe, effective use.

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.
