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 Guidelines for UK Patients

Optimal Timing for Viagra

Viagra should be taken 30-60 minutes before sexual activity for best results. The medication reaches peak effectiveness approximately one hour after taking, though some men may notice effects within 30 minutes. Planning ahead ensures the medication has sufficient time to work effectively when needed.

Duration of Effects

Viagra effects typically last 4-6 hours, though this doesn't mean an erection will persist throughout this period. Sexual stimulation is still required for the medication to work. The therapeutic window allows flexibility in timing intimate moments without rushing.

Factors Affecting Timing

Food intake significantly impacts Viagra's onset time. Fatty or heavy meals can delay absorption, potentially extending the time before effects begin. Taking Viagra on an empty stomach or after a light meal generally produces faster results. Alcohol consumption may also affect timing and effectiveness.

Dosage and Frequency

The standard starting dose is 50mg, which can be adjusted to 25mg or 100mg based on individual response and tolerability. Only one dose should be taken within any 24-hour period. EverydayMeds offers both Viagra and sildenafil options, allowing patients to choose between branded and generic formulations during checkout.

Safety Considerations

Before taking Viagra, ensure you're eligible through proper medical consultation. The medication isn't suitable for men taking nitrates or those with certain cardiovascular conditions. EverydayMeds provides comprehensive online consultations with UK-licensed prescribers to assess suitability and provide personalised timing advice.

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.
