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 and Managing Viagra Headaches Effectively

Why Does Viagra Cause Headaches?

Viagra (sildenafil) works by increasing blood flow, which can sometimes lead to headaches in approximately 10-15% of users. This occurs because the medication relaxes blood vessels throughout the body, not just in the penis. The temporary change in blood pressure and circulation can trigger headache symptoms, particularly during the first few doses as your body adjusts to the treatment.

Prevention Strategies for Viagra Headaches

Proper hydration is crucial when taking Viagra. Drink plenty of water before and after taking your dose, as dehydration can significantly increase headache risk. Avoid alcohol consumption, which can worsen side effects and reduce the medication's effectiveness. Taking Viagra on an empty stomach or with a light meal rather than after heavy, fatty foods can also help minimise side effects.

Dosage Adjustments for Headache Management

If you experience persistent headaches with Viagra, speak to your prescriber about dose adjustment. Starting with 25mg instead of the standard 50mg dose may reduce side effects whilst still providing effective treatment for erectile dysfunction. Some patients find that headaches diminish after taking the medication for several weeks as their body adapts to the treatment.

Safe Pain Relief Options

For mild to moderate headaches, paracetamol (500mg-1g) or ibuprofen (200-400mg) can be safely taken alongside Viagra. These common painkillers do not interact with sildenafil and can provide effective relief. Avoid aspirin if you're taking other medications, and never exceed recommended doses of any painkiller.

When to Seek Medical Advice

Contact your healthcare provider if headaches are severe, persistent, or accompanied by vision changes, chest pain, or dizziness. These could indicate a more serious reaction requiring immediate medical attention. At EverydayMeds, our clinical team is available to discuss any concerns about your ED treatment, whether you're using branded Viagra or generic sildenafil.

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.
