Acute Migraine Treatment
First-Line Treatment Algorithm
For mild-to-moderate migraine attacks, start with NSAIDs (ibuprofen 400–800 mg, naproxen sodium 500–825 mg, or aspirin 1000 mg) or acetaminophen 1000 mg; for moderate-to-severe attacks or when NSAIDs fail after 2–3 episodes, escalate immediately to a triptan (sumatriptan 50–100 mg, rizatriptan 10 mg, or eletriptan 40 mg). 1, 2
Specific NSAID Dosing
- Ibuprofen: 400–800 mg at onset, repeat every 6 hours as needed 1, 3
- Naproxen sodium: 500–825 mg at onset, repeat every 8–12 hours as needed 1, 3
- Aspirin: 1000 mg at onset 1, 3
- Combination therapy: Acetaminophen 1000 mg + aspirin 500–1000 mg + caffeine 130 mg provides synergistic benefit 1, 4
Triptan Selection and Dosing
- Sumatriptan: 50–100 mg oral (most evidence), 6 mg subcutaneous (fastest onset—15 minutes, 70–82% response rate), or 5–20 mg intranasal 1, 5, 3
- Rizatriptan: 10 mg oral (fastest oral triptan, peak at 60–90 minutes) 1, 3
- Eletriptan: 40 mg oral (reportedly more effective with fewer adverse effects than sumatriptan) 1, 3
- Zolmitriptan: 2.5–5 mg oral or nasal spray 1, 3
- Naratriptan: longest half-life, may reduce recurrence 1, 3
Combination Therapy (Strongest Evidence)
The combination of a triptan PLUS an NSAID (e.g., sumatriptan 50–100 mg + naproxen 500 mg) is superior to either agent alone, yielding 130 additional patients per 1000 who achieve sustained pain relief at 48 hours. 1
- This combination should be used for moderate-to-severe attacks or when monotherapy fails 1, 3
- Number-needed-to-treat for headache relief at 2 hours is 3.5 1
Antiemetics (Adjunctive and Monotherapy)
Metoclopramide 10 mg IV or prochlorperazine 10 mg IV provide direct analgesic effects beyond treating nausea and should be given 20–30 minutes before or with NSAIDs/triptans for synergistic benefit. 1, 3
- Metoclopramide is effective as monotherapy for acute attacks, especially when nausea/vomiting are prominent 1
- Prochlorperazine has comparable efficacy to metoclopramide with a more favorable side-effect profile (21% vs 50% adverse events) 1
- Both agents are contraindicated in pheochromocytoma, seizure disorders, and GI obstruction 1
Parenteral Options for Severe Attacks
IV "Migraine Cocktail"
Metoclopramide 10 mg IV + ketorolac 30 mg IV is the recommended first-line parenteral combination for severe migraine in urgent care settings. 1
- Ketorolac provides rapid onset with ~6 hours duration and minimal rebound risk 1
- Reduce ketorolac to 15 mg IV in patients ≥65 years or with renal impairment 1
Subcutaneous Sumatriptan
Subcutaneous sumatriptan 6 mg provides the highest efficacy among all triptan routes (59% pain-free at 2 hours, onset within 15 minutes) and should be used for rapidly escalating attacks or when oral routes fail. 1, 5, 3
Dihydroergotamine (DHE)
- Intranasal or IV DHE has good evidence as monotherapy for acute attacks 1, 3
- Contraindicated with concurrent triptan use (24-hour washout required), beta-blockers, uncontrolled hypertension, coronary artery disease, pregnancy, and sepsis 1, 5
Alternative Agents (Second-Line)
CGRP Antagonists (Gepants)
Ubrogepant 50–100 mg or rimegepant are third-line options for patients who do not tolerate or have inadequate response to triptan + NSAID combinations. 1
- No vasoconstriction—safe in cardiovascular disease, uncontrolled hypertension, or cerebrovascular disease 1
- Limit to ≤8 migraine attacks per 30 days to prevent medication-overuse headache 1
Ditans (Lasmiditan)
Lasmiditan 50–200 mg is a 5-HT1F agonist without vasoconstrictor activity, making it safe for cardiovascular disease, but patients must not drive for ≥8 hours due to CNS effects. 1
Contraindications to Triptans and Ergots
Triptans and DHE are absolutely contraindicated in:
- Ischemic heart disease, previous myocardial infarction, or coronary artery vasospasm 1, 5
- Uncontrolled hypertension 1, 5
- Cerebrovascular disease, history of stroke or TIA 1
- Basilar or hemiplegic migraine 1, 5
- Concurrent MAOI use 5
- Within 24 hours of each other (triptans and DHE) 1, 5
Medications to Avoid
Opioids (hydrocodone, oxycodone, morphine, codeine, tramadol) and butalbital-containing compounds are absolutely contraindicated for migraine treatment because they provide questionable efficacy, carry high risk of dependence, precipitate rebound headaches, and worsen long-term outcomes. 1, 6, 3, 2
- Reserve opioids only when all other evidence-based treatments are contraindicated, sedation is acceptable, and abuse risk has been formally assessed 1
- If an opioid must be used, butorphanol nasal spray has better evidence than other opioids 1
Critical Frequency Limitation
All acute migraine medications—NSAIDs, triptans, gepants, ditans, combination analgesics—must be limited to ≤2 days per week (≤10 days per month) to prevent medication-overuse headache, which paradoxically increases headache frequency and can lead to daily headaches. 1, 6, 3, 2
Treatment Timing
Treat early when pain is still mild for maximum effectiveness: ~50% of patients become pain-free at 2 hours when treated early versus ~28% when treatment is delayed until pain is moderate-to-severe. 1
Special Populations
Pregnancy
- Acetaminophen 1000 mg is the safest option during pregnancy 6
- Sumatriptan may be considered for selected patients after risk-benefit discussion 6
- Avoid NSAIDs in third trimester 6
- Valproate is strictly contraindicated (teratogenic) 1, 7
Uncontrolled Hypertension
- Acetaminophen 1000 mg is preferred; NSAIDs can further elevate blood pressure 1
- Triptans and DHE are contraindicated 1, 5
- Gepants (ubrogepant, rimegepant) are safe alternatives 1
Cardiovascular Disease
- Gepants or ditans are preferred; triptans and DHE are contraindicated 1, 2
- NSAIDs (ketorolac) should be used with caution in heart disease 1
Drug Allergies
- If NSAID allergy: use acetaminophen 1000 mg or triptan monotherapy 1
- If triptan contraindication: use NSAID + antiemetic or gepant 1
When Initial Treatment Fails
If one triptan fails after 2–3 headache episodes, switch to a different triptan (failure of one does not predict failure of others); if all triptans fail, escalate to gepants or ditans. 1, 3, 8
- Try each triptan for 2–3 separate attacks before abandoning it 1, 5, 3
- Consider route change (e.g., subcutaneous or intranasal) if oral fails 1, 8
- Add an NSAID to the triptan rather than increasing triptan frequency 1, 5
Preventive Therapy Indications
Initiate preventive therapy when:
- ≥2 migraine attacks per month causing disability ≥3 days 1, 7
- Acute medication use exceeds 2 days per week 1, 7
- Contraindication to or failure of acute treatments 1, 7
- Patient preference for prevention 7
First-line preventive agents include propranolol 80–240 mg/day, topiramate 50–100 mg/day, or candesartan 7
