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 Taking Viagra

When to Take Viagra

Viagra should be taken approximately 30-60 minutes before you plan to engage in sexual activity. The medication requires time to be absorbed and begin working effectively. Most men find that taking it about one hour beforehand provides optimal results, though individual response times may vary.

How Long Viagra Takes to Work

Viagra typically begins working within 30-60 minutes of taking the tablet. However, sexual stimulation is still required for the medication to be effective - it does not cause automatic erections. The onset time can be influenced by factors such as food intake, alcohol consumption, and individual metabolism.

Duration of Effects

The effects of Viagra can last between 4-6 hours after taking a dose. This does not mean you will have an erection for this entire period - rather, it means the medication may help you achieve erections during this timeframe when sexually aroused. The duration can vary between individuals and may be affected by factors such as age, overall health, and dosage.

Food and Timing Considerations

Taking Viagra with a large or high-fat meal may delay its onset of action. If you plan to eat before taking the medication, consider having a light meal to avoid potential delays. Alcohol can also affect how well Viagra works and may increase the risk of side effects, so moderation is advisable.

Dosage and Frequency

The standard starting dose is typically 50mg, though your prescriber may recommend 25mg or 100mg based on your individual needs and medical history. It is important never to take more than one dose in a 24-hour period, regardless of the strength prescribed. EverydayMeds offers both branded Viagra and generic sildenafil in various strengths, with patients able to choose their preferred option during the checkout process following consultation.

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.
