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.

Sildenafil Timing: What You Need to Know

How Long Before Sildenafil Takes Effect

Sildenafil tablets typically begin working within 30-60 minutes of taking them. However, the exact timing can vary between individuals based on factors such as age, overall health, and whether you've eaten recently. The medication reaches peak concentration in your bloodstream approximately 1-2 hours after taking it, which is when you're likely to experience optimal effects.

Duration of Action

Once sildenafil becomes active, its effects can last for 4-6 hours. This doesn't mean you'll have an erection for this entire period - sexual stimulation is still required for the medication to work. Instead, this timeframe represents the window during which the medication can help you achieve and maintain an erection when sexually aroused.

Factors That Affect Timing

Several factors can influence how quickly sildenafil works. Taking the tablet on an empty stomach generally results in faster absorption compared to taking it after a large or fatty meal. Alcohol consumption can also affect the medication's effectiveness and timing, so it's advisable to limit alcohol intake when planning to use sildenafil.

Optimal Timing Strategy

For best results, plan to take your sildenafil tablet approximately one hour before anticipated sexual activity. This allows sufficient time for the medication to be absorbed and become effective. Remember that sexual arousal is necessary for the medication to work - sildenafil enhances natural erectile function rather than causing automatic erections.

Important Safety Considerations

Never take more than one sildenafil tablet within a 24-hour period, regardless of the dosage strength. If you're considering treatment, EverydayMeds offers both generic sildenafil and branded Viagra options, allowing you to choose based on your preferences during the checkout process. Both contain the same active ingredient and work in the same way.

Getting Started with Treatment

Before starting sildenafil treatment, you'll need to complete a clinical assessment with a UK-licensed prescriber. This ensures the medication is suitable for your individual circumstances and doesn't interact with any existing medications or health conditions you may have.

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.
