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 Viagra Before Your First Dose

How Viagra Works in Your Body

Viagra contains sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you're sexually aroused, your body releases nitric oxide, which helps relax blood vessels in the penis. Viagra enhances this natural process by blocking an enzyme that restricts blood flow. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to work effectively.

What to Expect on Your First Dose

Most men start with a 50mg dose of Viagra, taken approximately one hour before sexual activity. The medication typically begins working within 30-60 minutes, though this can vary between individuals. Effects may last up to 4-6 hours, but this doesn't mean you'll have an erection for this entire period - rather, it's the window during which the medication can help you achieve an erection when sexually aroused.

Preparing for Your First Experience

To maximise effectiveness, avoid large or fatty meals before taking Viagra, as these can delay absorption and reduce the medication's impact. Limit alcohol consumption, as excessive drinking can interfere with the medication's effectiveness and increase the risk of side effects. Plan to take your dose when you're relaxed and not under time pressure, as anxiety can affect your response to treatment.

Common First-Time Side Effects

Many men experience mild side effects when first taking Viagra, which often diminish as your body adjusts to the medication. The most common include headaches, facial flushing, indigestion, and nasal congestion. These effects are usually temporary and mild. However, if you experience any severe side effects, chest pain, or an erection lasting more than four hours, seek immediate medical attention.

Branded Viagra vs Generic Sildenafil

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil during checkout. Both contain the same active ingredient - sildenafil citrate - and work identically. The main difference is cost, with generic sildenafil typically being more affordable whilst providing the same therapeutic benefits. Our UK-licensed prescribers can help you determine which option suits your needs and budget best.

Maximising Treatment Success

Success with Viagra often improves over the first few uses as anxiety decreases and you become more familiar with how the medication affects you. Maintain realistic expectations - whilst Viagra is highly effective for most men with erectile dysfunction, individual responses vary. Your prescriber may adjust your dose based on your response and any side effects experienced. Open communication with your healthcare provider ensures optimal treatment outcomes.

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.
