What are the recommended acute and prophylactic management strategies for migraine, including medication choices and dosing?

Migraine Management: Acute and Prophylactic Strategies

Acute Treatment

For most migraine sufferers, start with NSAIDs (aspirin, ibuprofen, naproxen sodium, or diclofenac) at adequate doses as first-line therapy, and if insufficient relief occurs after 2-3 attacks at proper dosing, immediately add a triptan to the NSAID rather than waiting for complete NSAID failure. 1

Stepwise Acute Treatment Algorithm

Mild to Moderate Migraine:

• First-line: NSAIDs alone (aspirin 900-1000mg, ibuprofen 400-800mg, naproxen sodium 500-550mg) 2
• Alternative: Acetaminophen + aspirin + caffeine combination (acetaminophen alone is NOT effective) 2
• Administer as early as possible in the attack for maximum efficacy 3

Moderate to Severe Migraine or NSAID Failure:

• Combination therapy: Triptan + NSAID (or triptan + acetaminophen if NSAIDs contraindicated) 1
• Proven triptans: sumatriptan (oral 50-100mg, subcutaneous 6mg), rizatriptan (10mg), zolmitriptan (2.5-5mg), naratriptan (2.5mg), eletriptan, almotriptan, frovatriptan 2, 3
• Subcutaneous sumatriptan reaches peak concentration fastest (15 minutes) and shows 70-82% efficacy—use for severe attacks 3

Migraine with Prominent Nausea/Vomiting:

• Use non-oral routes: subcutaneous sumatriptan, intranasal sumatriptan or DHE, or rizatriptan orally disintegrating tablet 2, 3
• Always add antiemetic: metoclopramide or prochlorperazine (treats nausea AND provides synergistic analgesia) 2, 3
• Nausea itself is disabling and warrants treatment even without vomiting 2

Third-Line Options (after triptan + NSAID failure):

• CGRP antagonists (gepants): rimegepant, ubrogepant, zavegepant 1
• Dihydroergotamine (DHE) nasal spray or parenteral 2
• Lasmiditan (ditan)—note: causes driving impairment for ≥8 hours 4, 1

Critical Pitfalls to Avoid

• Never use acetaminophen alone—no evidence of efficacy 2, 3
• Avoid opioids and butalbital—risk of dependency, medication overuse headache, and questionable efficacy 3, 4, 1
• Avoid oral ergotamine—poorly effective and potentially toxic 4
• Monitor frequency: Using acute medications >2 days/week or ≥15 days/month (NSAIDs) risks medication overuse headache 2, 1
• Don't switch triptans after single failure: Try 2-3 attacks before abandoning; if one triptan fails, try another—individual response varies 3

Prophylactic Treatment

Indications for Prevention

Evaluate ALL migraine patients for prophylaxis if they meet ANY of these criteria: 2

1. ≥2 attacks/month producing disability lasting ≥3 days/month
2. Contraindication to or failure of acute treatments
3. Using abortive medication >2 times/week
4. Uncommon migraine conditions (hemiplegic migraine, prolonged aura, migrainous infarction)

First-Line Prophylactic Agents

The following have proven efficacy and should be offered first: 2

• Propranolol: 80-240 mg/day
• Timolol: 20-30 mg/day
• Amitriptyline: 30-150 mg/day
• Divalproex sodium: 500-1500 mg/day
• Sodium valproate: 800-1500 mg/day
• Topiramate: (newer evidence supports first-line use) 5, 6

Newer first-line options (based on most recent guidelines):

• CGRP monoclonal antibodies: Positioned as first-line in American and Japanese guidelines, though access varies by country 7, 6, 8

Implementation Strategy

Start low, titrate slowly: Begin with lowest dose and increase gradually until clinical benefit achieved or limited by adverse effects 2

Allow adequate trial: Clinical benefit may take 2-3 months to manifest—do not abandon treatment prematurely 2

Discontinue interfering medications: Stop overused acute medications (especially ergotamine) once prevention initiated 2

Taper after stability: After period of control, consider tapering or discontinuing preventive therapy 2

Second-Line Prophylactic Options

• Flunarizine 10 mg/day (where available—not in US) 2
• Bisoprolol, naproxen, petasites 5
• Candesartan 9

Special Populations

Chronic Migraine (≥15 headache days/month):

• OnabotulinumtoxinA reserved after failure of multiple oral preventives 7, 6

Pediatric:

• Acute: acetaminophen or ibuprofen; intranasal sumatriptan 9
• Evidence gaps persist for preventive therapy 7

Patient Education Essentials

Counsel patients on: 2

• Treat attacks early after onset for maximum efficacy
• Use combination therapy (triptan + NSAID) when appropriate
• Track attacks with diary: frequency, severity, duration, disability, treatment response, adverse effects
• Realistic expectations: discuss medication overuse headache risk
• Active self-management improves outcomes

Reevaluate therapy regularly through ongoing dialogue about expectations, goals, and treatment response 2
