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.

What to Expect During Your First Viagra Experience

Understanding How Viagra Works

Viagra contains sildenafil citrate, a PDE5 inhibitor that 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. The medication works by blocking an enzyme that restricts blood flow, making it easier to achieve and maintain an erection during sexual activity.

Your First Consultation Process

Before receiving Viagra, you'll complete a clinical assessment with a UK-licensed prescriber. This consultation evaluates your medical history, current medications, and cardiovascular health to ensure Viagra is safe for you. The prescriber will ask about any heart conditions, blood pressure medications, and other treatments you're taking, as some combinations can be dangerous.

Choosing Between Viagra and Sildenafil

At EverydayMeds, you can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient and work identically - the main difference is cost. Generic sildenafil offers the same effectiveness as branded Viagra but at a lower price point, making treatment more accessible for many patients.

Taking Your First Dose

Most first-time users start with 50mg, taken 30-60 minutes before sexual activity. Take the tablet with water, and avoid heavy or fatty meals beforehand as these can delay the medication's onset. Remember that you should only take one dose per 24-hour period, regardless of whether the first attempt is successful.

What to Expect: Timing and Effects

Viagra typically begins working within 30-60 minutes, with effects lasting 4-6 hours. This doesn't mean you'll have an erection for hours - rather, you'll find it easier to achieve erections during this window when sexually stimulated. Many first-time users notice improved confidence even before the physical effects become apparent.

Managing First-Time Side Effects

Common side effects include headaches, facial flushing, and mild dizziness. These are usually temporary and decrease as your body adjusts to the medication. If you experience chest pain, prolonged erections lasting over 4 hours, or sudden vision changes, seek immediate medical attention.

When Viagra May Not Be Suitable

Viagra isn't appropriate for everyone. You cannot take it if you're using nitrate medications (like GTN spray), have severe heart disease, or have had a recent heart attack or stroke. Your prescriber will review these factors during your consultation to ensure your safety.

Optimising Your Treatment

If your first experience isn't optimal, don't be discouraged. Your prescriber may adjust your dose to 25mg or 100mg based on effectiveness and tolerability. Some patients find that reducing alcohol consumption and managing stress improves their results with ED 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.
