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.

When to Take Viagra for Best Results

Viagra should be taken approximately 30-60 minutes before sexual activity. The medication needs time to be absorbed into your bloodstream and begin working effectively. Some men may notice effects within 30 minutes, while others may need up to an hour. Taking it on an empty stomach typically produces faster results compared to after heavy meals.

How Long Does Viagra Last?

Viagra effects can last between 4-6 hours in most men, though individual response varies. This doesn't mean you'll have an erection for this entire period - sexual stimulation is still required for the medication to work. The window simply represents when the medication remains active in your system and can help achieve erections when aroused.

Factors Affecting Viagra Timing

Several factors can influence how quickly Viagra works and how long it lasts. Age, overall health, other medications, and alcohol consumption can all impact timing. Younger men often experience faster onset, while certain health conditions may slow absorption. Heavy drinking can reduce effectiveness and delay onset significantly.

Food intake plays a crucial role in timing. Fatty or heavy meals can delay Viagra absorption by 30-60 minutes. For fastest results, take on an empty stomach or after light meals only. Grapefruit and grapefruit juice should be avoided as they can affect how your body processes the medication.

Viagra vs Sildenafil Generic Timing

Both branded Viagra and generic sildenafil contain the same active ingredient and have identical timing profiles. EverydayMeds offers both options - the choice between branded or generic comes down to personal preference and cost considerations. Generic sildenafil works exactly the same way with identical timing requirements.

Safe Timing Guidelines

Never take more than one dose within 24 hours, regardless of effectiveness. If Viagra doesn't work on first attempt, don't take additional doses the same day. Speak with your prescriber about dose adjustments if needed. If you experience an erection lasting over 4 hours, seek immediate medical attention as this requires urgent treatment.

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.
