Migraines are common ED visits. Most respond to oral meds or rest at home. But sometimes, a patient presents with status migrainosus — a severe migraine lasting >72 hours, unrelieved by typical therapy. For rookies, this can be frustrating: the patient is miserable, your usual meds fail, and you need a structured approach to break the cycle.
What Is Status Migrainosus?
- Defined as a migraine attack lasting >72 hours, either continuously or with minimal relief.
- Pain is often severe, disabling, and refractory to home medications.
- Triggers: stress, sleep disturbance, medication overuse, hormonal shifts, infection.
Step 1: Rule Out Secondary Causes
Not every “severe headache” is migraine. Always exclude red flags:
- Sudden onset (“thunderclap”) → think SAH.
- Fever, neck stiffness → meningitis.
- New neuro deficit → stroke.
- Headache with cancer, pregnancy, or immunosuppression → consider secondary causes.
If presentation consistent with typical migraine and past history, proceed with treatment.
Step 2: ED Treatment Principles
Goals: relieve pain, stop nausea/vomiting, restore function, prevent recurrence.
1. IV Hydration
- Normal saline or LR bolus.
- Dehydration worsens migraine.
2. Antiemetics (dopamine antagonists)
- Metoclopramide 10 mg IV or prochlorperazine 10 mg IV.
- Give with diphenhydramine 25 mg IV to reduce akathisia/extrapyramidal side effects.
3. NSAIDs
- Ketorolac 30 mg IV or 60 mg IM (if no renal/GI contraindications).
- Effective for acute migraine relief.
4. Triptans
- Sumatriptan 6 mg SC if not already used at home.
- Avoid in CAD, uncontrolled HTN, or stroke/TIA history.
5. Magnesium
- Magnesium sulfate 1–2 g IV over 30 min.
- Especially useful in menstrual migraine or aura-related migraines.
6. Corticosteroids
- Dexamethasone 10–20 mg IV.
- Not for acute relief, but reduces recurrence in following 24–72 hrs.
7. Rescue Options (Refractory Cases)
- Valproic acid 1 g IV over 15 min.
- Chlorpromazine or olanzapine IV/IM (if resistant to first-line antiemetics).
- Admission if uncontrolled despite multi-agent therapy.
Step 3: Avoid Pitfalls
- Opioids are not first-line. They don’t treat the underlying process and increase risk of medication overuse headaches.
- Don’t overtreat with triptans/ergots — risk of vasospasm and rebound.
- Be cautious with frequent ED visits → screen for medication overuse headache.
Common Rookie Mistakes
- Discharging after partial relief without preventing recurrence (forgot dexamethasone).
- Using opioids too early.
- Not ruling out secondary headache causes.
- Forgetting to address nausea/vomiting — patients need both pain and GI symptom relief.
Rookie Pearls
- Prochlorperazine + diphenhydramine IV is one of the most effective ED combos.
- Add dexamethasone to prevent rebound headache.
- Magnesium is low-risk and often very effective — use it.
- Always reassess before discharge — ensure sustained relief.
- Educate on outpatient follow-up and avoiding medication overuse.
Take-Home Message
For rookies:
- Status migrainosus = migraine lasting >72 hrs, refractory to usual meds.
- Rule out secondary causes first.
- Treat with multi-modal regimen: fluids, antiemetics, NSAID, ± triptan, magnesium, dexamethasone.
- Avoid opioids; prevent recurrence with steroids.
Remember: Your job is not just to stop the headache — it’s to keep it from coming back tomorrow.
