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 Viagra Works and Your Treatment Options

Starting Your Viagra Treatment with EverydayMeds

Beginning ED treatment has never been more straightforward. Our online consultation process connects you with UK-licensed prescribers who assess your suitability for Viagra or sildenafil treatment. The consultation typically takes 5-10 minutes and covers your medical history, current medications, and symptoms.

During checkout, you can choose between branded Viagra or generic sildenafil - both contain identical active ingredients and work in exactly the same way. Many patients opt for sildenafil as it offers the same effectiveness at a lower cost, whilst others prefer the original Viagra brand.

Understanding How Viagra and Sildenafil Work

Viagra works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). This action increases blood flow to the penis during sexual arousal, helping to achieve and maintain erections. Importantly, Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.

The medication typically begins working within 30-60 minutes of taking it, with effects potentially lasting 4-6 hours. This doesn't mean your erection will last this long, but rather that you may find it easier to achieve erections during this timeframe when sexually aroused.

Dosage Options and Getting Started

Both Viagra and sildenafil are available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which can be adjusted up to 100mg or down to 25mg based on effectiveness and any side effects experienced.

Take your tablet 30-60 minutes before sexual activity, and remember that fatty meals may delay how quickly it works. You should only take one dose within any 24-hour period.

Safety Considerations and Who Can Take Viagra

Viagra and sildenafil are prescription-only medicines suitable for adult men experiencing erectile dysfunction. However, they're not suitable for everyone. The medication cannot be taken alongside nitrate medications (such as GTN spray) due to potentially dangerous interactions.

Our online consultation will assess whether Viagra is appropriate for your individual circumstances, considering factors such as cardiovascular health, current medications, and medical history. This ensures you receive safe, effective treatment.

Ordering Process and Next Steps

Once your consultation is approved, you can complete your order and choose your preferred delivery option. We offer discreet packaging and next-day delivery services. Your medication will be dispensed by our UK-registered pharmacy and delivered directly to your chosen address.

If you have questions about your treatment, our pharmacy team is available to provide guidance and support throughout your treatment journey.

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.
