How Does Viagra Work? Get Your Assessment Today

Viagra works by increasing blood flow to the penis when you're sexually aroused, helping you achieve and maintain an erection. As a PDE5 inhibitor, it blocks specific enzymes that restrict blood flow. At EverydayMeds, our UK-licensed clinicians can assess your suitability for Viagra through a simple online consultation. You can choose between branded Viagra or generic sildenafil during checkout, both containing the same active ingredient but at different price points.

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.

Your Viagra Consultation Process Explained

How Viagra Works in Your Body

Viagra contains sildenafil citrate, which belongs to a group of medicines called PDE5 inhibitors. When you're sexually aroused, your body naturally releases nitric oxide, which increases blood flow to the penis. Viagra works by blocking the PDE5 enzyme that can restrict this blood flow, helping you achieve and maintain an erection suitable for sexual activity.

It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required. The medication typically begins working within 30-60 minutes of taking it, and its effects can last up to 4-6 hours, though this doesn't mean your erection will last this long.

Starting Your Online Assessment

Our streamlined consultation process makes accessing Viagra treatment straightforward and discreet. You'll begin by completing a comprehensive medical questionnaire that covers your health history, current medications, and symptoms. This assessment typically takes 5-10 minutes and asks about cardiovascular health, blood pressure, and any medications you're currently taking.

Our UK-licensed prescribers need this information to ensure Viagra is safe and suitable for you. The assessment includes questions about nitrate medications, recent heart problems, liver function, and blood pressure issues, as these can affect whether Viagra is appropriate for your situation.

Clinical Review by UK-Licensed Prescribers

Once you've submitted your consultation, one of our experienced UK-licensed clinicians will review your responses. They'll assess your suitability for treatment based on current clinical guidelines and your individual health profile. Most assessments are reviewed within 2-4 hours during working days.

If approved, you'll receive a prescription for Viagra, and you can choose your preferred strength - typically starting with 50mg, though 25mg and 100mg options are available. Your prescriber may recommend starting with a lower dose if you're taking other medications or have certain health conditions.

Choosing Between Viagra and Sildenafil

At checkout, you can select between branded Viagra manufactured by Pfizer or generic sildenafil. Both contain exactly the same active ingredient (sildenafil citrate) and work identically in your body. The main difference is cost - generic sildenafil offers significant savings whilst providing the same clinical effectiveness.

Many patients choose generic sildenafil for ongoing treatment once they've established that the medication works well for them. Your choice doesn't affect the strength or effectiveness of your treatment, and you can switch between branded and generic options in future orders.

Important Safety Information

Viagra isn't suitable for everyone. You shouldn't take it if you're using nitrate medications for chest pain, as this combination can cause a dangerous drop in blood pressure. It's also not recommended if you have severe heart disease, recent stroke, very low blood pressure, or certain eye conditions.

Common side effects may include headaches, flushing, indigestion, or nasal congestion. These are usually mild and temporary. Always take Viagra exactly as prescribed - maximum one tablet per 24 hours, and avoid taking it with large or fatty meals as this can delay its effectiveness.

Discreet Delivery and Ongoing Support

Once your prescription is approved and you've completed your order, we'll arrange discreet delivery to your chosen address. Packages arrive in plain packaging with no indication of contents, typically within 24-48 hours for UK addresses.

Our patient support team remains available for any questions about your treatment. You can also easily reorder through your patient account, with streamlined repeat consultations for ongoing treatment when clinically appropriate.

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.
