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 Maximum Effectiveness

Standard Timing Guidelines

Viagra should typically be taken 30-60 minutes before sexual activity. The medication reaches peak concentration in your bloodstream approximately one hour after ingestion, making this the optimal window for effectiveness. However, individual response times may vary based on factors including age, metabolism, and overall health status.

Impact of Food on Timing

Taking Viagra on an empty stomach generally provides faster onset of action. Fatty meals can significantly delay absorption, potentially extending the time needed for the medication to become effective by up to 60 minutes. If you've eaten a large or high-fat meal, consider waiting 2-3 hours before taking your dose, or allow extra time before planned sexual activity.

Duration of Effects

Viagra's effects typically last 4-6 hours, though this doesn't mean you'll maintain an erection for this entire period. The medication creates a window during which achieving an erection becomes easier with sexual stimulation. Some men report effects lasting slightly longer, particularly with the 100mg dose, though individual experiences vary considerably.

Dosage Timing Considerations

Your prescribed dose affects both onset and duration. The 25mg dose may work slightly faster but with potentially shorter duration, whilst the 100mg dose might take longer to become effective but could last longer. EverydayMeds offers both branded Viagra and generic sildenafil in all three strengths (25mg, 50mg, 100mg), allowing patients to choose their preferred option during checkout following consultation.

Important Safety Reminders

Never exceed one dose within 24 hours, regardless of timing. If your first dose doesn't provide the desired effect, resist the temptation to take another tablet the same day. Our UK-licensed prescribers can adjust your dosage or provide alternative recommendations during follow-up consultations if needed.

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.
