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 Guidelines for Viagra and Sildenafil

When to Take Viagra for Best Results

Viagra (sildenafil citrate) should typically be taken 30-60 minutes before planned sexual activity. The medication reaches peak effectiveness approximately one hour after administration. EverydayMeds provides both branded Viagra and generic sildenafil, with identical timing recommendations for both formulations.

Food and Timing Considerations

Taking Viagra on an empty stomach generally produces faster results. Heavy or fatty meals can significantly delay the medication's onset, potentially extending the time to effectiveness by up to two hours. Light meals are generally acceptable and may not significantly impact timing. Patients should plan accordingly based on their meal schedule.

Alcohol and Viagra Timing

Moderate alcohol consumption may be acceptable, but excessive drinking can reduce Viagra's effectiveness and increase the risk of side effects such as dizziness or low blood pressure. It's advisable to limit alcohol intake when taking the medication for optimal results.

Duration of Effects

Viagra's effects can last 4-6 hours after taking the tablet. This doesn't mean an erection will persist for this duration, but rather that the medication may help achieve erections during this timeframe when combined with sexual stimulation. The medication doesn't cause automatic erections.

Dosage and Timing Flexibility

Standard starting doses are typically 50mg, which can be adjusted to 25mg or 100mg based on individual response and tolerability. Regardless of dosage strength, the timing recommendations remain consistent. Only one dose should be taken within any 24-hour period.

Factors Affecting Timing

Individual factors can influence how quickly Viagra works, including age, overall health, other medications, and stress levels. Some men may notice effects within 30 minutes, while others may need the full hour. Consistency in timing helps establish what works best for each individual.

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.
