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.

Viagra Timing: Essential Facts for Best Results

Optimal Timing for Taking Viagra

Viagra should be taken 30-60 minutes before you plan to engage in sexual activity. This timing window allows the medication to be absorbed into your bloodstream and begin working effectively. The active ingredient sildenafil citrate needs time to block the PDE5 enzyme and improve blood flow to the penis when sexual arousal occurs.

How Long Does Viagra Last?

Viagra's effects can last up to 4-6 hours after taking the tablet. However, this doesn't mean you'll have an erection for this entire duration. The medication creates a window of opportunity during which you may find it easier to achieve and maintain an erection when sexually stimulated. Most men find the peak effectiveness occurs within the first 2-3 hours after taking Viagra.

Factors That Affect Viagra Timing

Several factors can influence how quickly Viagra works and how long it remains effective. Taking Viagra on an empty stomach typically results in faster absorption compared to taking it after a large or fatty meal, which can delay onset by 30-60 minutes. Alcohol consumption should be limited as it can reduce the medication's effectiveness and increase the risk of side effects.

Dosage and Timing Considerations

The standard starting dose of Viagra is 50mg, though your prescriber may adjust this to 25mg or 100mg based on your response and tolerability. Regardless of the dose, the timing recommendations remain the same. Remember that you should never take more than one dose of Viagra in a 24-hour period, even if the first dose seems less effective than expected.

Planning Ahead with Viagra

Unlike some ED treatments, Viagra is taken on-demand rather than daily. This means you need to plan ahead for sexual activity. Many men find it helpful to take Viagra about an hour before they anticipate intimacy, allowing flexibility in timing while ensuring the medication has taken effect. EverydayMeds provides both branded Viagra and generic sildenafil options, giving you choice between the original formulation and a more cost-effective alternative with the same active ingredient.

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.
