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.

Managing Viagra Headaches: Professional Solutions

Why Viagra Causes Headaches

Headaches occur because sildenafil (the active ingredient in both Viagra and generic alternatives) works by dilating blood vessels. This vasodilation effect, whilst improving blood flow to help with erectile dysfunction, can also affect blood vessels in the head, leading to tension headaches or mild throbbing sensations. Studies show approximately 15-20% of men experience headaches when taking sildenafil-based treatments.

Immediate Headache Relief Strategies

If you develop a headache after taking Viagra, over-the-counter painkillers like paracetamol (up to 1000mg) or ibuprofen (400mg) are safe and effective options. These medications do not interact with sildenafil and can be taken as needed. Ensure you're drinking plenty of water - dehydration commonly worsens medication-related headaches. A cold compress applied to the forehead for 10-15 minutes may also provide relief.

Dosage Adjustments for Headache Prevention

Many men find that starting with a lower 25mg dose significantly reduces headache frequency whilst still providing effective results. Your prescriber can adjust your dosage based on your response. Some patients discover that generic sildenafil causes fewer side effects than branded Viagra, though both contain identical active ingredients. EverydayMeds offers both options, allowing you to find the most suitable treatment for your needs.

When to Seek Medical Advice

Contact a healthcare professional if headaches are severe, persistent, or accompanied by vision changes, chest pain, or dizziness. Sudden, severe headaches are uncommon but require immediate medical attention. Most Viagra-related headaches are mild and temporary, typically resolving within 2-4 hours as the medication leaves your system.

Long-term Management Tips

Regular users often find headaches diminish over time as their body adjusts to the medication. Maintaining consistent timing, taking sildenafil on a relatively empty stomach, and avoiding excessive alcohol can help minimise side effects. If headaches persist, discuss alternative PDE5 inhibitors with your prescriber, as individual responses vary between different medications in this class.

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.
