Can over-the-counter medicine treat cluster headaches?

Cluster attacks can build rapidly and may end before a tablet has had time to work. Taking repeated doses without guidance can expose you to side effects and may contribute to medication-overuse headache. The one-sided pain around the eye, along with tearing, redness, or a blocked nostril, is a pattern a clinician should assess rather than treat indefinitely with self-care. A diagnosis also helps separate cluster headache from other causes of headache and facial pain.

Check the label before taking any non-prescription medicine and do not combine products with the same active ingredient. Keep a record of dose, timing, response, sleep, alcohol exposure, and other possible triggers. Arrange a GP consultation, especially if attacks are recurring or interrupting sleep. A clinician may discuss a rapid treatment for attacks and a preventive medicine, taking account of your other conditions, current medicines, and blood pressure.

Seek emergency care for a sudden thunderclap headache, new neurological symptoms, fainting, seizure, severe confusion, fever with a stiff neck, or vision loss. A red painful eye with visual change requires urgent assessment. Get prompt advice when a headache is new, progressively different, follows an injury, or begins during pregnancy. Do not keep escalating self-treatment while waiting for a diagnosis.

Is an over-the-counter product appropriate for me at all? What should I use at the first sign of an attack? How can I avoid medication-overuse headache? Do I need a preventive plan or referral?
