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 How to Prevent Them

Understanding Viagra-Related Headaches

Headaches occur in approximately 16% of men taking Viagra, making them one of the most frequently reported side effects. These headaches result from sildenafil's mechanism of action - the same process that improves blood flow to treat erectile dysfunction also affects blood vessels throughout the body, including those in the head and neck.

Immediate Relief Strategies

When a headache strikes after taking Viagra, paracetamol (up to 1000mg) or ibuprofen (200-400mg) can provide effective relief. These medications are safe to use alongside Viagra and won't interfere with its effectiveness. Applying a cold compress to your forehead or the back of your neck can also help reduce discomfort.

Prevention Techniques

Staying properly hydrated is crucial - drink plenty of water before taking Viagra and continue throughout the day. Avoid alcohol, which can worsen headaches and reduce Viagra's effectiveness. If you experience predictable headaches, taking a preventive paracetamol dose 30 minutes before your Viagra may help.

Dosage Considerations

If headaches persist, speak with your prescriber about reducing your dose. Many men find that lowering from 100mg to 50mg, or from 50mg to 25mg, significantly reduces headache frequency whilst maintaining treatment effectiveness. EverydayMeds offers both branded Viagra and generic sildenafil in all three strengths, giving you flexibility to find your optimal dose.

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 more serious side effects requiring immediate attention. Most Viagra headaches are mild to moderate and resolve within a few hours as the medication's effects diminish.

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.
