Migraines are a neurological disease best known as severe headaches. Usually, migraines cause 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 migraines 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.
- Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.
- There are no life-threatening causes of migraine, although, migraine should be distinguished from intracranial berry aneurysms ruptures and subarachnoid hemorrhages, which represent real emergencies.
- Allergic reactions
- Bright lights, loud noises, and certain odors or perfumes
- Physical or emotional stress
- Changes in sleep patterns
- Smoking or exposure to smoke
- Skipping meals
- Menstrual cycle fluctuations, birth control pills
- Exposure to pesticides (sprayed fruits/vegetables)
- Tension headaches
- Foods containing tyramine (red wine, aged cheese, smoked fish, chicken livers, figs, and some beans), monosodium glutamate (MSG), or nitrates (like bacon, hot dogs, and salami)
- Other foods such as chocolate, nuts, peanut butter, avocado, banana, citrus, onions, dairy products, and fermented or pickled foods.
- Drugs like apremilast, conjugated estrogens, Cidofovir
|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|
|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|
|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|
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|
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
Sumatriptan: 6 mg sc — may repeat in 1 h if no response. (Max dose 12 mg in 24-h period
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
Ondansetron: 4-8 mg IVP over 30 sec
|More than 50% relief?|
|Admit the patient and investigate further|
- Be aware of patients who describe a sudden severe thunderclap headache, described as the worst headache of their lives. Perform a non-contrasted CT scan of the head to rule out subarachnoid hemorrhage; if negative, perform a lumbar puncture.
- Distinguish migraine from meningitis if in addition of photophobia and phonophobia, neck stiffness and fever coexist.
- Perform an MRI or CT scan of the head, if intracranial hypertension is suspected. Morning predominant headache accompanied by vomiting supports the diagnosis of intracranial tumors.
- Do not administer Drospirenone and Ethinyl estradiol or Norelgestromin and Ethinyl Estradiol in patients older than 35.
- Do not administer NSAIDs more than 15 days straight do to possible rebound headache.
