Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Moises Romo, M.D.

Overview

Migraine is a neurological disease best known for severe headaches that are its most salient symptom.. Usually, migraine causes episodes of severe or moderate headache (which is often one-sided and pulsating) lasting between several hours to three days, accompanied by gastrointestinal upsets, such as nausea and vomiting, and a heightened sensitivity to bright lights (photophobia) and noise (phonophobia). Approximately one-third of people who experience migraine get a preceding aura. Migraines' secondary characteristics are inconsistent. Triggers precipitating a particular episode of migraine vary widely. The efficacy of the simplest treatment, applying warmth or coolness to the affected area of the head, varies between persons, sometimes worsening the migraine.

• Common cause 5

Management

Patient presents with a complaint of headache

Does patient have new or different headaches in past 6 mo?

Yes

Evaluate red flags • Systemic symptoms: fever, chills, meningismus • Secondary risk factors: malignancy, immunosuppression • Neurologic symptoms or abnormal signs • Onset: sudden/abrupt • Older age >50 years • Pattern change: first headache or different from previous headache history

Yes to any

Appropriate pain management, consultations and admission

Appropriate evaluation for secondary causes

No

1. Are headaches recurrent that interfere with work, family or social function? 2. Do headaches last at least 4 h if untreated?

Yes to both questions

Diagnose migraine

Evaluate yellow flags • Drug seeking with underlying chronic pain • Recurrent ED visits without appropriate outpatient management/ PCP follow-up or • OARRS report shows opiate use ± multisourcing

Assess for treatment contraindications: pregnancy, allergies, comorbid conditions

Avoid opioids

Treat with Ketorolac 30 mg IVP or 30-60 mg IM + Metoclopramide 10 mg IVP over 2 min or Ondansetron 8 mg IVP + Diphenhydramine 25-50 mg + IVP IV fl uids for hydration

More than 50% relief?

Yes

Discharge patient 1. Disposition 2. No opiate scripts 3. If responsive to ketorolac, discharge with toradol script 10 mg PO tid for up to 5 days 4. If response to sumatriptan, discharge with script 5. If response to DHE, discharge with Migranal nasal spray script or DHE sc script 6. If responsive to valproate, valproic taper 250 tid for 3 d, 250 bid for3 d, 250 qd for 3 d, then stop 7. Discharge with PCP follow-up 8. If no PCP, refer to PCP

No

Treat with Sumatriptan: 6 mg sc — may repeat in 1 h if no response. (Max dose 12 mg in 24-h period OR DHE-45: Start with 0.25 mg IVP over 1 min or sc. If needed repeat in 1 h 1 mg IVP over 1 min or 1 mg sc. or choose an antiemetic: Prochlorperazine 10 mg IVP over 30 sec q2-4h prn OR Metoclopramide: 10 mg IVP over 2 min OR Ondansetron: 4-8 mg IVP over 30 sec

More than 50% relief?

No

Admit the patient and investigate further
