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 Viagra and Sildenafil Treatment

When to Take Viagra for Best Results

Viagra should be taken approximately 30-60 minutes before sexual activity. This timing allows the medication to be absorbed into your bloodstream and begin working effectively. The active ingredient sildenafil requires time to reach therapeutic levels in your system, which is why advance planning is important for optimal results.

Duration of Effects

Viagra's effects typically last between 4-6 hours after taking the tablet. However, this doesn't mean you'll have an erection for this entire period. The medication creates a window of opportunity during which you may find it easier to achieve and maintain an erection when sexually aroused. Individual response times can vary based on factors including age, overall health, and other medications.

Factors That Affect Timing

Several factors can influence how quickly Viagra works. Food intake plays a significant role - fatty or heavy meals can delay absorption and reduce effectiveness. For best results, take Viagra on an empty stomach or after a light meal. Alcohol consumption should be minimal, as excessive drinking can impair the medication's effectiveness and increase the risk of side effects.

Dosage Timing Considerations

EverydayMeds provides both Viagra and sildenafil in standard dosages of 25mg, 50mg, and 100mg. The starting dose is typically 50mg, taken once daily as needed. Your prescriber may adjust this based on your response and any side effects experienced. Never take more than one dose in a 24-hour period, regardless of the strength prescribed.

Planning Ahead

Unlike some alternatives, Viagra requires advance planning due to its timing requirements. Some patients find this less spontaneous than desired. During your consultation with our UK-licensed prescribers, discuss whether Viagra or sildenafil timing suits your lifestyle, or if alternative treatments might be more appropriate for your circumstances.

Important Safety Reminders

Always follow your prescriber's specific instructions regarding timing and dosage. If you're taking any medications containing nitrates, do not use Viagra or sildenafil, as this combination can cause dangerous drops in blood pressure. Contact EverydayMeds if you have questions about timing or experience any concerning symptoms after taking your medication.

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.
