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.

Understanding Viagra Timing and Duration

How Long Before Viagra Takes Effect

Viagra typically begins working within 30 to 60 minutes of taking the tablet. The exact timing can vary between individuals and may be influenced by factors such as food intake, alcohol consumption, and individual metabolism. For optimal results, many patients find taking Viagra on an empty stomach or after a light meal works best.

Peak Effectiveness and Duration

Viagra reaches peak effectiveness approximately one to two hours after taking the tablet. The medication's effects can last up to four to six hours, though this does not mean an erection will persist for this duration. Sexual stimulation is still required for Viagra to work effectively, and erections should subside naturally after sexual activity concludes.

Food and Alcohol Considerations

High-fat meals can significantly delay Viagra's absorption, potentially reducing its effectiveness and delaying onset. Alcohol in moderation is generally acceptable, but excessive drinking can impair sexual function and may increase the risk of side effects such as dizziness or low blood pressure. Planning your meal timing around when you intend to take Viagra can help ensure optimal results.

Dosage and Frequency Guidelines

The standard starting dose is 50mg, which can be adjusted to 25mg or 100mg based on effectiveness and tolerance. It's crucial never to exceed one dose in a 24-hour period, regardless of the strength taken. Patients should not take additional doses if the first dose doesn't work as expected on a particular occasion.

Choosing Between Viagra and Sildenafil

At EverydayMeds, patients can choose between branded Viagra and generic Sildenafil during checkout. Both contain the same active ingredient and work identically, but Sildenafil offers a more cost-effective option. The timing guidelines apply equally to both formulations, and the choice often comes down to personal preference and budget considerations.

When to Seek Medical Advice

If you experience an erection lasting more than four hours, seek immediate medical attention. Contact your healthcare provider if Viagra stops working effectively or if you experience concerning side effects. Regular medication reviews ensure continued suitability and optimal dosing for your individual needs.

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.
