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 with Viagra Treatment Online

How to Order Viagra Online from EverydayMeds

Starting your Viagra treatment is straightforward through our online consultation process. First, complete our confidential clinical assessment form, which asks about your medical history, current medications, and symptoms. A UK-licensed prescriber will review your information and determine if Viagra is suitable for you. If approved, you can choose between branded Viagra or generic Sildenafil at checkout - both contain the same active ingredient but Sildenafil offers a more budget-friendly option.

Understanding Viagra's Timing and Effectiveness

Viagra typically takes 30-60 minutes to start working, though some men may notice effects sooner or later. The medication works by increasing blood flow to the penis when you're sexually aroused - it won't cause an automatic erection. Sexual stimulation is still required for the medication to be effective. The effects can last up to 4-6 hours, giving you a window of opportunity rather than a constant erection.

Factors That May Affect How Quickly Viagra Works

Several factors can influence how long Viagra takes to work. Taking the medication on an empty stomach generally leads to faster absorption, whilst fatty meals can delay the onset by up to an hour. Alcohol consumption may also slow down the medication's effectiveness and can reduce your ability to achieve an erection. Your overall health, age, and the dosage prescribed (25mg, 50mg, or 100mg) can also impact timing.

Maximising Your Treatment Results

To get the best results from your Viagra treatment, take the tablet approximately one hour before planned sexual activity. Avoid heavy or fatty meals beforehand, and limit alcohol consumption. Remember that you should never take more than one dose in a 24-hour period. If you find the medication isn't working as expected, speak to your prescriber about adjusting your dosage rather than taking additional tablets.

Branded vs Generic: Understanding Your Options

Both branded Viagra and generic Sildenafil contain exactly the same active ingredient (sildenafil citrate) and work in the same way. The timing and effectiveness are identical between the two options. The main difference is cost - generic Sildenafil typically offers significant savings whilst providing the same clinical benefits. EverydayMeds gives you the choice between both options during checkout, allowing you to select based on your budget and preferences.

What to Expect During Treatment

When starting Viagra treatment, your prescriber will typically recommend beginning with a 50mg dose, which can be adjusted based on how well it works and any side effects you might experience. Common side effects may include headache, facial flushing, or indigestion, which are usually mild and temporary. The medication's effects typically peak around 60-90 minutes after taking it, then gradually decline over the following hours.

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.
