What should you know about wine headache?

Alcohol can affect sleep, fluid balance and blood vessels, all of which may contribute to head pain. Some people notice symptoms with a particular type of wine or after drinking without food. A blocked nose, facial pressure, fever, stress, or a usual migraine pattern may point to another contributor rather than the wine alone. Keeping a simple note of the drink, food, sleep, timing and symptoms can make patterns clearer.

A wine-related headache does not confirm an allergy. Hives, swelling, wheeze, or throat tightness after a drink need medical assessment because they are different from an isolated headache.

Stop drinking alcohol, rest in a quiet setting, and sip water or an oral rehydration drink if you can keep fluids down. Eat a light meal if you have not eaten and avoid driving or activities that need clear concentration. Use pain relief only if it is suitable for you and compatible with your medicines; a pharmacist or clinician can help if you are unsure.

If headaches repeatedly follow wine, consider avoiding the suspected drink until you have discussed the pattern with a clinician, especially if the reaction includes nasal or breathing symptoms.

Seek urgent care for a sudden severe headache, a headache after a head injury, fainting, confusion, weakness, trouble speaking, a stiff neck, persistent vomiting, or new vision loss. Get medical advice for headache with fever or rash, or for a headache that continues to recur or changes from your usual pattern.

Ask whether the timing and associated symptoms suggest alcohol, dehydration, migraine, sinus symptoms, or another cause. Bring a list of medicines and supplements, as well as details of any flushing, rash, wheezing, or nasal congestion after wine.
