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.

Why Viagra Causes Headaches and Prevention Tips

Understanding Viagra-Related Headaches

Headaches occur in approximately 10-15% of men taking Viagra (sildenafil). These headaches develop because sildenafil widens blood vessels throughout the body, not just in the penis. This vasodilation can affect blood vessels in the head and neck, potentially triggering tension headaches or mild migraines. The good news is that these headaches are typically mild to moderate and often improve as your body adjusts to the medication.

Immediate Headache Management Strategies

If you develop a headache after taking Viagra, several safe options may provide relief. Paracetamol (up to 1000mg) or ibuprofen (200-400mg) can be taken alongside Viagra without dangerous interactions. However, never combine headache medications containing nitrates with Viagra, as this combination can cause a dangerous drop in blood pressure. Applying a cold compress to your forehead or temples may also provide natural relief.

Prevention Through Proper Dosing

Many headaches can be prevented by starting with the lowest effective dose. EverydayMeds offers Viagra in 25mg, 50mg, and 100mg strengths, with 50mg being the standard starting dose. If you experience headaches with 50mg, your prescriber may recommend reducing to 25mg. Generic sildenafil is also available as a cost-effective alternative with identical active ingredients and side effect profile.

Lifestyle Modifications for Headache Prevention

Staying properly hydrated is crucial for preventing Viagra-related headaches. Drink plenty of water before taking your dose and continue hydrating throughout the day. Avoid excessive alcohol consumption, which can worsen both headaches and erectile dysfunction. Taking Viagra on an empty stomach or with a light meal may reduce both headache risk and improve the medication's effectiveness.

When to Seek Medical Advice

Whilst mild headaches are common and manageable, certain symptoms require immediate medical attention. Contact your healthcare provider if you experience severe headaches, sudden vision changes, chest pain, or headaches that worsen over time. These could indicate more serious complications requiring prompt evaluation. Your EverydayMeds prescriber can also adjust your treatment plan if headaches significantly impact your quality of life.

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.
