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: Clinical Solutions

Understanding Why Viagra Pills Cause Headaches

Viagra and generic sildenafil work by increasing blood flow through PDE5 inhibition. This mechanism can cause temporary blood vessel dilation in the head, leading to tension headaches in some users. The MHRA recognises headaches as a common side effect, affecting approximately 16% of men taking sildenafil citrate.

Immediate Relief Strategies

If you develop a headache after taking your Viagra pill, paracetamol (up to 1000mg) or ibuprofen (400mg) can provide effective relief. Both pain relievers are safe to use with sildenafil and won't interfere with its effectiveness for erectile dysfunction. Ensure adequate hydration by drinking at least 500ml of water when taking your medication.

Dose Optimisation Options

Many patients find headaches reduce when switching from 100mg to 50mg sildenafil. Clinical studies show 50mg remains effective for most men whilst reducing side effect frequency. EverydayMeds offers flexible dosing options for both Viagra and generic sildenafil, allowing you to find your optimal balance between effectiveness and tolerability.

Lifestyle Modifications

Avoiding alcohol on treatment days can significantly reduce headache severity. Fatty meals may also contribute to side effects whilst delaying onset of action. Consider taking your Viagra pill on a lighter stomach and limiting alcohol intake to improve your experience.

When to Seek Clinical Review

Contact your prescriber if headaches are severe, persist beyond 24 hours, or worsen over time. EverydayMeds provides ongoing clinical support to help optimise your treatment. Alternative PDE5 inhibitors like tadalafil may be suitable if sildenafil headaches prove problematic despite dose adjustment.

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.
