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.

Understanding and Preventing Viagra-Related Headaches

Why Does Viagra Cause Headaches?

Viagra (sildenafil) works by increasing blood flow throughout the body, not just to the penis. This vasodilation effect can cause blood vessels in the head to widen, leading to headaches in some users. The same mechanism that helps treat erectile dysfunction can temporarily affect blood vessels elsewhere in the body, resulting in this common side effect.

Practical Headache Prevention Strategies

Several approaches may help reduce headache occurrence when taking Viagra. Starting with the lowest effective dose, typically 25mg, allows your body to adjust gradually. Many patients find that headaches become less frequent as their body adapts to the medication over several uses. Ensuring adequate hydration before taking Viagra is crucial, as dehydration can worsen headache symptoms.

Timing your dose appropriately can also make a difference. Taking Viagra on an empty stomach may increase the likelihood of side effects, whilst having a light meal beforehand might help reduce headache intensity. Avoiding alcohol when using Viagra is recommended, as both substances can lower blood pressure and potentially worsen headache symptoms.

Safe Headache Management Options

If you do experience a headache after taking Viagra, standard over-the-counter pain relievers are generally safe to use. Paracetamol (acetaminophen) is often the first choice, as it's gentle on the stomach and doesn't interact with sildenafil. Ibuprofen may also be used, though it should be taken with food to protect the stomach lining.

When to Seek Medical Advice

Whilst mild headaches are common and usually manageable, certain symptoms warrant immediate medical attention. Severe, sudden-onset headaches, particularly those accompanied by vision changes, chest pain, or difficulty breathing, require urgent medical assessment. If headaches persist beyond 24 hours or significantly impact your daily activities, consult with a healthcare professional.

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.
