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.

Complete Viagra Timing Schedule & Food Guidelines

Optimal Timing for Viagra Administration

Viagra typically begins working within 30-60 minutes of administration, though individual response times may vary. For most patients, taking Viagra approximately one hour before planned sexual activity provides the best balance of effectiveness and spontaneity. The medication's effects can last up to 4-6 hours, creating a window of opportunity rather than an immediate response.

Food and Alcohol Considerations

Heavy or high-fat meals can significantly delay Viagra's absorption and onset of action. Clinical studies suggest avoiding substantial meals for at least 2 hours before taking your dose. Light meals generally don't interfere with effectiveness. Moderate alcohol consumption is typically acceptable, but excessive drinking can reduce the medication's effectiveness and increase the risk of side effects such as dizziness or low blood pressure.

Dosage Timing and Safety Guidelines

The standard starting dose is 50mg, taken once daily as needed. Your prescriber may adjust this to 25mg or 100mg based on your individual response and tolerability. It's crucial never to exceed one dose within 24 hours, regardless of effectiveness. Some patients find that splitting doses or taking smaller amounts more frequently improves results, but this should only be done under medical supervision.

Maximising Treatment Effectiveness

Sexual arousal remains essential for Viagra to work effectively - the medication enhances natural physiological responses rather than creating automatic reactions. Stress, anxiety, and fatigue can all impact effectiveness, so timing your dose when you feel relaxed and well-rested often improves outcomes. EverydayMeds patients can choose between branded Viagra and generic sildenafil at checkout, both containing the same active ingredient with identical timing requirements.

When to Contact Your Prescriber

If you consistently find that standard timing doesn't work for your lifestyle or if you experience concerning side effects, speak with your EverydayMeds prescriber about adjusting your treatment plan. Alternative PDE5 inhibitors with different timing profiles may be more suitable for some patients.

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.
