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.

Understanding How Long Before Viagra Works

Viagra typically begins working within 30-60 minutes of taking it, though this can vary between individuals. The medication contains sildenafil citrate, which increases blood flow to the penis when you're sexually aroused. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective.

Factors That Affect Viagra's Onset Time

Several factors can influence how quickly Viagra works for you. Taking the medication on an empty stomach generally leads to faster absorption, whilst fatty meals may delay its effects by up to an hour. Your age, overall health, and other medications you're taking can also impact how long before Viagra works in your system.

How Our Online Consultation Works

Starting your Viagra consultation with EverydayMeds is straightforward and completely confidential. Our online assessment takes just a few minutes to complete and covers your medical history, current medications, and symptoms. This information helps our UK-licensed prescribers determine whether Viagra treatment is suitable and safe for you.

During the consultation, you'll answer questions about your cardiovascular health, as this is crucial for safe Viagra use. The medication can interact with certain heart conditions and medications, particularly nitrates, so thorough assessment is essential before prescribing.

Choosing Between Viagra and Generic Sildenafil

At checkout, you'll have the option to choose between branded Viagra and generic sildenafil. Both contain the same active ingredient (sildenafil citrate) and work identically - the main difference is cost. Generic sildenafil offers the same effectiveness at a lower price point, making treatment more accessible for many patients.

Our prescribers can advise which option might be most suitable based on your individual circumstances and preferences. Both medications are available in 25mg, 50mg, and 100mg strengths, with 50mg being the typical starting dose.

What to Expect After Your Consultation

Once you've completed your consultation, our UK-licensed prescribers will review your assessment, typically within hours. If approved, your medication will be dispensed by our registered pharmacy and dispatched for discreet delivery. We'll also provide clear guidance on how to take your medication safely and what to expect.

Remember that Viagra works best when taken 30-60 minutes before sexual activity, and you should never take more than one dose in a 24-hour period. If you find the medication isn't working as expected, don't increase the dose yourself - contact our clinical team for advice on adjusting your treatment.

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.
