2 Red flag features Progressive headache Sudden inset worst ever headache Jaw claudication and scalp tenderness Significant fever or systemic upset New altered headache in elderly New altered headache in immunocompromised New altered headache in patient with known malignancy Examination abnormal: Eye movements Fundi e.g. papilledema Pupils and pupillary reactions Limb and or gait ataxia Tendon reflexes / plantar

3 Migraine headache acute treatment options At headache onset: Analgesia: NSAID e.g. Ibuprofen mg or Naproxen mg Anti-emetic: e.g. Metoclopramide 10 mg, Domperidone mg Sumatriptan mg All up to 6 times / month

7 Migraine headache prevention options Identify / avoid / modify migraine triggers Propranolol mg od Metoprolol mg daily Topiramate mg bd or Amitriptyline mg nocte

8 Tension type headache prevention options Lifestyle and headache trigger avoidance Consider acupuncture

9 Cluster headache prevention options Verapamil mg / day (with normal ECG)

10 Chronic medication over-use headache prevention options Reduce / stop analgesia Monitor with headache diary Further treatment based upon diagnosis e.g. migraine, tension type, etc.

11 Episodic headache management options For migraine, tension type and daily headaches: Monitor and adjust treatment Consider withdrawing preventative rx after 4 6 months Avoid increasing analgesic use
