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.

Optimal Timing for Viagra and Sildenafil

Standard Timing Guidelines

Viagra and sildenafil should typically be taken 30-60 minutes before sexual activity. This timeframe allows the medication to be absorbed into your system and begin working effectively. The active ingredient sildenafil citrate requires time to increase blood flow to the penis when sexual arousal occurs.

Factors That Affect Timing

Food intake significantly impacts how quickly Viagra works. Taking the medication on an empty stomach generally provides faster results, whilst fatty or heavy meals can delay absorption by up to two hours. Alcohol consumption may also reduce effectiveness and should be limited when using ED treatments.

Duration and Frequency

The effects of both Viagra and sildenafil typically last 4-6 hours, though this doesn't mean an erection will persist for this duration. Sexual stimulation is still required for the medication to work. It's crucial never to take more than one dose within 24 hours, regardless of effectiveness.

Choosing Between Viagra and Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil at checkout, allowing patients to select their preferred option during the ordering process. Both contain the same active ingredient and work identically - the main difference is cost, with sildenafil being the more affordable generic alternative.

Starting Your Treatment

Most men begin with a 50mg dose, which can be adjusted to 25mg or 100mg based on effectiveness and any side effects experienced. Our online consultation process ensures you receive the appropriate dosage and timing guidance from UK-licensed prescribers who review your medical history and current medications.

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.
