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.

Viagra Timing: Key Considerations for Best Results

Optimal Timing for Taking Viagra

Viagra should be taken 30-60 minutes before sexual activity for best results. The medication typically begins working within 30 minutes for most men, though this can vary based on individual factors such as age, health status, and whether food has been consumed recently. Effects may last up to 4-6 hours, providing a window of opportunity rather than a continuous erection.

Dosage and Frequency Guidelines

The standard starting dose is 50mg, which can be adjusted to 25mg or 100mg based on effectiveness and tolerability. Crucially, only one dose should be taken within any 24-hour period. Taking more than the recommended dose increases the risk of serious side effects, including dangerous drops in blood pressure. At EverydayMeds, patients can choose between branded Viagra and generic sildenafil during checkout, both containing the same active ingredient.

Food and Alcohol Considerations

Large or fatty meals can significantly delay Viagra's onset of action. High-fat foods slow the absorption of sildenafil, potentially delaying effectiveness by several hours. Light meals are preferable before taking the medication. Whilst small amounts of alcohol may not interfere significantly, excessive drinking can impair the medication's effectiveness and increase the risk of side effects such as dizziness or low blood pressure.

Important Safety Considerations

Before taking Viagra, ensure you're not using nitrate medications (such as GTN spray for angina), as this combination can cause dangerous blood pressure drops. Men with certain heart conditions, recent strokes, or severe liver problems should not use Viagra. A proper medical consultation is essential to determine suitability and appropriate dosing. EverydayMeds' UK-licensed prescribers conduct thorough assessments to ensure safe treatment.

Maximising Effectiveness

Sexual stimulation remains necessary for Viagra to work effectively. The medication doesn't cause automatic erections but enhances the natural response to sexual arousal. Stress, anxiety, and relationship issues can affect effectiveness regardless of timing. Creating a relaxed environment and maintaining realistic expectations can help optimise results with either branded Viagra or generic sildenafil alternatives.

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.
