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

When to Take Viagra for Best Results

Viagra should typically be taken 30-60 minutes before sexual activity. This timeframe allows the medication to be properly absorbed and begin working effectively. Some men may find that Viagra works more quickly on an empty stomach, whilst others may not notice significant differences with food.

Duration of Effects

Once taken, Viagra can remain effective for approximately 4-6 hours. This doesn't mean an erection will last this entire time - sexual stimulation is still required for the medication to work. The duration may vary between individuals based on factors such as age, metabolism, and overall health status.

Factors Affecting Absorption Timing

Several factors can influence how quickly Viagra works. Large or fatty meals may delay absorption by up to an hour, so timing your dose accordingly is important. Alcohol consumption should be limited as it may reduce effectiveness and increase the risk of side effects such as dizziness or low blood pressure.

Dosage Timing Guidelines

Standard doses include 25mg, 50mg, and 100mg tablets. Most men start with 50mg, which can be adjusted based on effectiveness and tolerability. Never take more than one dose within a 24-hour period, regardless of the strength used. EverydayMeds offers both branded Viagra and generic sildenafil - you can choose your preferred option during checkout.

Planning Around Daily Activities

Consider your daily routine when planning to take Viagra. If you're taking other medications, particularly those for heart conditions or blood pressure, timing becomes even more important. Our clinical team can provide personalised guidance on the best timing for your individual circumstances during your consultation.

What to Avoid

Certain substances can interfere with Viagra's effectiveness or cause dangerous interactions. Never combine with nitrate medications such as GTN spray. Grapefruit juice may also affect how your body processes the medication, so it's best avoided close to dosing time.

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.
