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-Related Headaches: Clinical Guidance

Why Viagra Gel and Tablets Cause Headaches

Viagra and generic sildenafil work by relaxing blood vessels to improve blood flow to the penis. This same mechanism can affect blood vessels throughout your body, including those in your head, potentially causing headaches. The MHRA recognises headaches as a common side effect, occurring in approximately 16% of users taking standard doses.

Immediate Headache Management Strategies

If you develop a headache after taking Viagra gel or tablets, several approaches may provide relief. Paracetamol (500mg-1g) is generally safe to use alongside sildenafil, though you should check with your pharmacist or prescriber first. Ibuprofen may also be suitable unless you have contraindications. Ensure adequate hydration as dehydration can worsen headaches.

Prevention Through Dosage Optimisation

Many patients find that starting with a lower dose reduces headache frequency. EverydayMeds prescribers can adjust your dose from the standard 50mg to 25mg if headaches are problematic. Both branded Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths, allowing for personalised dosing that balances effectiveness with tolerability.

Timing and Lifestyle Adjustments

Taking Viagra gel or tablets with food may slow absorption and reduce the intensity of side effects including headaches. Avoid alcohol before taking sildenafil as this can worsen headaches and reduce effectiveness. If headaches persist or are severe, contact your prescriber as dose adjustment or alternative treatments may be appropriate.

When to Seek Medical Advice

Severe or persistent headaches warrant medical attention. If you experience sudden, severe headache unlike your usual pattern, seek immediate medical help. EverydayMeds clinical team can review your treatment and suggest alternatives if headaches significantly impact your quality of life. Both Viagra and generic sildenafil options remain available with appropriate clinical oversight.

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.
