  • Precautions
  1. See Headache Red Flags (e.g. Thunderclap Headache, Fever)
  2. Do not miss serious Headache Causes (e.g. Subarachnoid Hemorrhage, Meningitis)
    1. See Acute Secondary Headache
  3. Avoid agents less effective in treating Headache (non-DopamineAntagonist Antiemetics)
    1. Promethazine (Phenergan) 12.5 mg IV
    2. Hydroxyzine
    3. Opioids (e.g. Hydromorphone, Morphine)
    4. ParenteralLidocaine
    5. Octreotide
  1. Precautions
    1. Administer via Parenteral Route (IV preferred or IM)
      1. Oral route is unlikely to be effective with these agents due to their high first-pass metabolism
    2. Extrapyramidal Side Effects (especially Akathisia) occurs in 5-40% of cases when given these Anti-emetics
      1. Administer these agents slowly (e.g. dilute in saline and run over 20 minutes)
        1. Lower risk of Extrapyramidal Side Effects (Akathisia) when slowly infused
        2. Parlak (2007) Postgrad Med 83(984):664-8 +PMID:17916877 [PubMed]
      2. Diphenhydramine (Benadryl)
        1. Guidelines no longer recommended prophylactic use to prevent Extrapyramidal Side Effects
        2. Has not been found effective in reducing Extrapyramidal Side Effects
        3. Consider administering if Akathisia occurs
        4. Friedman (2016) Ann Emerg Med 67(1): 32-9 [PubMed]
  2. Prochlorperazine (Compazine) with IV hydration
    1. Often effective for aborting intractable Headache
    2. Consider with Diphenhydramine 12.5 to 50 mg IV to reduce risk of Akathisia, Dystonia
    3. Adults: 10 mg IV
    4. Child: 0.15 mg/kg IV
  3. Metoclopramide (Reglan) 10 mg IV
    1. Excellent first-line agent for Migraine with Nausea
    2. Optimal dose appears to be 10 mg IV
    3. Colman (2004) BMJ 329(7479): 1369-73 [PubMed]
    4. Friedman (2011) Ann Emerg Med 57(5): 475-82 +PMID:21227540 [PubMed]
  4. Droperidol (Inapsine)
    1. Dose: 1.25 to 5 mg slow IV or IM (typical dose 2.5 mg IV, doses as low as 0.625 may be effective)
    2. FDA black box warning due to QT Prolongation risk
    3. EKG monitoring for single or cummulative doses above 1.25 mg
    4. Olanzapine (Zyprexa) or Haloperidol (Haldol) have been used as alternatives in Migraine Headache
  1. Precautions
    1. Do not use if Coronary Artery Disease, Cerebrovascular Accident, Uncontrolled Hypertension
    2. Do not use with MAO Inhibitors, and Exercise caution with other serotonergic agents (e.g. SSRI)
    3. Triptans have high Incidence of side effects with Emergency Department use (30%)
      1. Dizziness
      2. Blurred Vision
      3. Confusion
      4. Chest Pain
  2. Triptans (preferred)
    1. Sumatriptan (Imitrex) intranasal, oral or 6 mg subcutaneous
    2. Zolmitriptan (Zomig) intranasal or oral
  3. Dihydroergotamine Mesylate (DHE, not generally used)
    1. DHE 0.5 to 1 mg IV every 8 hours up to cummulative maximum of 3 mg
    2. Migranal 1 spray in each nostril and may repeat once after 15 minutes

  • Preparations
  • Analgesic or Anti-inflammatory
  1. Ketorolac (Toradol)
    1. Dose: 30 mg IV (60 mg IM)
      1. However, one study on general pain management in ED found maximal effect at only 10 mg IV
      2. Motov (2017) Ann Emerg Med 70(2): 177-84 +PMID: 27993418 [PubMed]
  2. Dexamethasone
    1. Dose: 4 to 10 mg IV or oral
      1. Doses above 10 mg are unlikely to provide added benefit
      2. Studies showed benefit at 4 to 8 mg (dose 4 mg may offer adequate benefit and lower risk)
    2. Hydrocortisone or Methylprednisolone IV could be used as alternative (however Dexamethasone is preferred)
    3. Onset of activity is delayed at least 6 hours from administration
    4. May prevent Headache recurrence in following 48-72 hours

    1. Still used in 47% of emergency visits, but not recommended in guidelines
  • Preparations
  • Other agents that have been used historically
  1. Intravenous Fluids
    1. Most emergency department Headache protocols use Intravenous Fluid bolus
    2. However, no benefit found in Headache relief when combined with Metoclopramide
      1. Balbin (2016) Am J Emerg Med 34(4): 713-6 +PMID:26825817 [PubMed]
  2. Antipsychotics with Analgesic and Antiemetic properties
