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: Practical Solutions

Why Does Viagra Cause Headaches?

Viagra works by dilating blood vessels to increase blood flow to the penis. This same mechanism can affect blood vessels throughout the body, including those in the head, potentially leading to headaches. The vasodilation effect is temporary and typically subsides as the medication is processed by your body.

Immediate Relief Strategies

If you experience a headache after taking Viagra, paracetamol or ibuprofen can provide effective relief. These common painkillers do not interact with sildenafil and are safe to use together. Ensure you stay well-hydrated by drinking plenty of water, as dehydration can worsen headache symptoms.

Applying a cold compress to your forehead or the back of your neck may also help alleviate discomfort. Rest in a quiet, dimly lit environment if possible, as this can reduce headache intensity.

Prevention Techniques

Starting with a lower dose may help reduce headache frequency. Many men find that beginning with 25mg or 50mg produces fewer side effects whilst still providing effective results. Your prescriber can adjust your dose based on how you respond to treatment.

Timing your dose correctly can also help. Taking Viagra on an empty stomach or with a light meal may reduce the likelihood of side effects compared to taking it after a heavy, fatty meal.

When to Seek Medical Advice

Whilst mild to moderate headaches are common and usually manageable, certain symptoms require medical attention. Contact your GP or prescriber if you experience severe headaches that don't respond to painkillers, headaches accompanied by vision changes, or headaches that persist for more than 24 hours after taking Viagra.

Alternative Options

EverydayMeds offers both branded Viagra and generic sildenafil during checkout. Some patients find that switching between formulations or adjusting the dose helps minimise side effects whilst maintaining effectiveness. Your healthcare provider can discuss whether alternative ED treatments might be more suitable if headaches continue to be problematic.

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.
