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.

Effective Strategies for Sildenafil Headache Management

Why Sildenafil May Cause Headaches

Sildenafil tablets work by increasing blood flow, which can occasionally lead to headaches in some patients. This side effect typically occurs because the medication affects blood vessels throughout the body, not just in the treatment area. The headaches are usually mild to moderate and tend to improve as your body adjusts to the medication.

Immediate Relief Strategies

If you experience a headache after taking sildenafil, paracetamol is generally safe to use alongside your treatment. Ensure you stay well-hydrated by drinking plenty of water before and after taking your tablet. Avoid alcohol, as this can worsen headache symptoms and may interfere with the effectiveness of sildenafil. Rest in a quiet, dark environment if possible.

When to Contact Your Healthcare Provider

Contact your prescriber if headaches are severe, persistent, or accompanied by vision changes, chest pain, or dizziness. These symptoms require immediate medical attention. Your healthcare provider may recommend adjusting your dose or switching between different sildenafil formulations to find the most suitable option for you.

Treatment Options at EverydayMeds

Both contain the same active ingredient and are equally effective. Our UK-licensed prescribers can help determine the most appropriate dose and formulation to minimise side effects whilst maintaining treatment effectiveness through our confidential online consultation service.

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.
