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 Long Does Viagra Last and How to Access It Online

Viagra contains the active ingredient sildenafil citrate, which typically provides effects lasting 4-6 hours. It's important to understand that this doesn't mean you'll have an erection for the entire duration - sexual stimulation is still required for the medication to work effectively.

Beginning Your Online Consultation

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

The consultation process includes questions about your cardiovascular health, as erectile dysfunction treatments can interact with certain heart medications, particularly nitrates. You'll also be asked about any liver problems, recent strokes or heart attacks, and current blood pressure medications.

Choosing Between Viagra and Sildenafil

At checkout, you can choose between branded Viagra and generic sildenafil - both contain the same active ingredient and work identically. Many patients opt for sildenafil as it offers the same effectiveness at a lower cost. Both options are available in 25mg, 50mg, and 100mg strengths.

Most men start with a 50mg dose, taken 30-60 minutes before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if the initial dose isn't effective enough. Remember, you should only take one dose within any 24-hour period.

What to Expect During Treatment

Viagra begins working within 30-60 minutes of taking it, with effects lasting up to 6 hours. Taking it on an empty stomach may help it work faster, as fatty meals can delay absorption. The medication doesn't cause automatic erections - you'll still need sexual stimulation for it to be effective.

Common side effects may include headaches, flushing, indigestion, or nasal congestion. These are usually mild and temporary. If you experience chest pain, sudden vision changes, or an erection lasting more than 4 hours, seek immediate medical attention.

Completing Your Order

Once approved by our prescriber, your medication will be dispensed by our UK-registered pharmacy and dispatched with discrete packaging. We offer next-day delivery across the UK, so you can start treatment quickly and conveniently.

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.
