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.

Professional Headache Management for ED Treatment

Why Viagra May Cause Headaches

Viagra and sildenafil work by increasing blood flow through vasodilation, which can affect blood vessels throughout the body, not just in the genital area. This mechanism may cause temporary changes in blood pressure and circulation patterns that can trigger headaches in some patients. The intensity typically varies between individuals and may decrease as your body adjusts to the medication over several uses.

Immediate Headache Relief Options

When experiencing mild to moderate headaches after taking Viagra, paracetamol (up to 1000mg) or ibuprofen (up to 400mg) may provide relief. These common painkillers do not interact dangerously with sildenafil and are generally safe to use alongside ED treatment. However, avoid aspirin if you have any cardiovascular concerns, and always follow the recommended dosages on pain relief packaging.

Preventative Measures

Proper hydration before taking Viagra may significantly reduce headache likelihood. Drink plenty of water throughout the day and avoid excessive alcohol consumption, which can worsen both dehydration and potential side effects. Taking your dose on a relatively empty stomach may also help, as fatty foods can affect how the medication is absorbed and processed by your body.

When to Consult Your Prescriber

Persistent or severe headaches warrant professional medical advice. Your prescriber may recommend adjusting your dose from the standard 50mg to 25mg, or exploring whether the generic sildenafil option might be more suitable for your individual response. EverydayMeds provides both Viagra and sildenafil alternatives, allowing flexibility in your treatment approach under proper medical guidance.

Choosing Between Viagra and Sildenafil

Both branded Viagra and generic sildenafil contain the same active ingredient and work identically. Some patients report different tolerance levels between formulations, though this varies individually. The generic option offers significant cost savings whilst maintaining the same clinical effectiveness, making it an attractive choice for long-term treatment management.

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.
