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 Windows for Sildenafil

Sildenafil citrate typically begins working within 30-60 minutes after taking. For most men, taking sildenafil approximately one hour before planned sexual activity provides the best balance of effectiveness and spontaneity. The medication reaches peak concentration in your bloodstream around 60-90 minutes after ingestion, which is when you're likely to experience maximum effectiveness.

Factors That Affect Sildenafil Timing

Several factors can influence how quickly sildenafil works. Food intake significantly impacts absorption - fatty meals can delay effectiveness by up to 90 minutes. Alcohol consumption may also affect both timing and effectiveness. Age and overall health status can influence absorption rates, with older adults sometimes requiring slightly longer for the medication to take effect.

Planning Your Dose Schedule

Never take more than one dose of sildenafil in 24 hours, regardless of timing. If you find the standard 50mg dose isn't effective within the expected timeframe, consult your prescriber about adjusting the dose rather than taking additional tablets. Some men benefit from the 25mg dose taken 45 minutes before activity, while others may need 100mg taken 60-75 minutes beforehand.

EverydayMeds Sildenafil Options

EverydayMeds offers both branded Viagra and generic sildenafil citrate, allowing you to choose the option that best suits your needs and budget. Both contain identical active ingredients and follow the same timing guidelines. Our UK-licensed prescribers can help determine the optimal dose and timing schedule during your confidential consultation.

When to Seek Timing Adjustments

If sildenafil consistently takes longer than 90 minutes to work, or if you experience timing-related issues, speak with a healthcare provider. Factors such as other medications, underlying health conditions, or the need for dose adjustment may require professional evaluation. Never adjust timing by taking multiple doses or increasing frequency beyond the 24-hour limit.

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.
