  • Take 30-60 minutes before sexual activity on an empty stomach for optimal absorption
  • Start with 50mg dose and adjust based on effectiveness and tolerability
  • Avoid fatty meals and excessive alcohol which can delay onset of action
  • Ensure sexual stimulation is present as Viagra requires arousal to be effective

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.

Optimising Your Viagra Treatment Results

Understanding Viagra vs Sildenafil Options

Both Viagra (branded) and sildenafil (generic) contain the same active ingredient - sildenafil citrate. EverydayMeds provides both options, allowing patients to choose based on personal preference and budget considerations. The generic sildenafil offers identical clinical effectiveness at a lower cost, whilst branded Viagra may be preferred by some patients. Both require the same clinical assessment and prescription from our UK-licensed prescribers.

Dosage Optimisation for Best Results

The standard starting dose is 50mg, taken approximately one hour before sexual activity. Based on individual response and tolerability, this may be adjusted to 25mg or increased to a maximum of 100mg. Only one dose should be taken within a 24-hour period. Clinical studies demonstrate that proper dosing significantly impacts treatment effectiveness, with most men finding their optimal dose within the first few attempts.

Timing and Administration Guidelines

For maximum effectiveness, take Viagra on an empty stomach or after a light meal. Fatty foods can delay absorption by up to two hours. The medication typically begins working within 30-60 minutes, with effects potentially lasting 4-6 hours. This timeframe provides flexibility for spontaneous intimacy whilst ensuring the medication remains effective when needed.

Lifestyle Factors Affecting Effectiveness

Several lifestyle factors can influence Viagra's effectiveness. Excessive alcohol consumption may impair the medication's action and reduce sexual performance. Regular exercise, maintaining a healthy weight, and managing stress levels can enhance treatment outcomes. Smoking cessation is particularly beneficial as it improves blood circulation, which is essential for Viagra's mechanism of action.

Safety Considerations and Contraindications

Viagra is not suitable for all men. Those taking nitrate medications, having severe cardiovascular conditions, or certain medical histories require alternative treatments. Our clinical assessment process ensures safe prescribing by evaluating medical history, current medications, and individual health factors. This comprehensive approach maximises both safety and treatment effectiveness for each patient.

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.
