Treatment Guidelines for Migraines
Acute Treatment of Migraine
For moderate to severe migraine attacks, start with combination therapy of a triptan plus an NSAID (such as sumatriptan 50-100 mg with naproxen 500 mg), as this provides superior efficacy compared to either agent alone. 1
First-Line Acute Treatment Algorithm
Mild to Moderate Attacks:
- Begin with NSAIDs (ibuprofen 400-800 mg, naproxen 500-825 mg, or aspirin 1000 mg) or acetaminophen 1000 mg 1, 2
- If NSAIDs alone fail after 2-3 episodes, escalate to triptan + NSAID combination 1
Moderate to Severe Attacks:
- Initiate combination therapy immediately: triptan + NSAID (or acetaminophen if NSAIDs contraindicated) 1
- This combination provides 130 more patients per 1000 achieving sustained pain relief at 48 hours compared to monotherapy 1
- Counsel patients to treat early in the attack while pain is still mild for maximum effectiveness 1, 2
Specific Triptan Options (choose based on patient factors):
- Sumatriptan 50-100 mg oral (most studied, generic available) 1, 2
- Rizatriptan 10 mg (fastest oral triptan, reaches peak in 60-90 minutes) 2
- Eletriptan 40 mg or zolmitriptan 2.5-5 mg (reportedly more effective with fewer adverse effects than sumatriptan) 2
- Naratriptan (longest half-life, may decrease recurrence headaches) 2
- Almotriptan, frovatriptan 1
Route Selection Based on Symptoms
Severe Nausea/Vomiting Present:
- Use non-oral routes: subcutaneous sumatriptan 6 mg (provides 70-82% pain relief within 15 minutes) 2
- Alternative: intranasal sumatriptan 5-20 mg or zolmitriptan nasal spray 2
- Add antiemetic: metoclopramide 10 mg IV or prochlorperazine 10 mg IV/25 mg rectal 2
Rapid Progression to Peak Intensity:
- Subcutaneous sumatriptan 6 mg provides highest efficacy with onset within 15 minutes 2
Second-Line Options When Triptans Fail or Are Contraindicated
If one triptan fails, try a different triptan—failure of one does not predict failure of others 2, 3
If all triptans fail or are contraindicated (cardiovascular disease, uncontrolled hypertension):
- CGRP antagonists-gepants: rimegepant, ubrogepant 50-100 mg, or zavegepant 1, 2
- Ditan: lasmiditan 50-200 mg (warning: no driving for 8 hours due to CNS effects) 1, 2
- Dihydroergotamine (DHE) nasal spray or IV 1, 2
Emergency Department/IV Treatment
Optimal IV "Headache Cocktail":
- Metoclopramide 10 mg IV (provides direct analgesic effects beyond antiemetic properties) 2
- PLUS Ketorolac 30 mg IV (rapid onset, 6-hour duration, minimal rebound risk) 2
- Alternative: Prochlorperazine 10 mg IV (comparable efficacy to metoclopramide, 21% adverse event rate vs 50% for chlorpromazine) 2
Alternative IV Options:
- Dihydroergotamine (DHE) IV 2
- Avoid: Opioids and butalbital (lead to dependency, rebound headaches, medication overuse headache) 1, 2
Critical Frequency Limitation
Limit ALL acute migraine medications to no more than 2 days per week (10 days per month) to prevent medication-overuse headache 1, 2
- NSAIDs/acetaminophen: ≥15 days/month triggers medication-overuse headache 1
- Triptans: ≥10 days/month triggers medication-overuse headache 1
- If needing acute treatment more than twice weekly, initiate preventive therapy immediately 1, 2
Preventive Treatment of Migraine
Preventive therapy should be initiated for patients experiencing ≥2 migraine attacks per month with disability lasting ≥3 days, or those using acute medications more than twice weekly. 1, 4
Indications for Preventive Therapy
- Two or more migraine attacks per month producing disability lasting ≥3 days 4
- Use of abortive medication more than twice per week 4
- Contraindications to or failure of acute treatments 4
- Uncommon migraine conditions (hemiplegic migraine, prolonged aura, migrainous infarction) 4
First-Line Preventive Medications (Start Here)
The 2025 American College of Physicians guideline prioritizes cost-effective options first:
Beta-Blockers (first choice for most patients):
- Propranolol 80-240 mg/day (FDA-approved, strong evidence) 1, 4
- Metoprolol 1, 4
- Timolol 20-30 mg/day 4
- Atenolol or bisoprolol 4
- Particularly useful for patients with comorbid hypertension 1, 4
Antiseizure Medications:
Angiotensin Receptor Blocker:
SNRI:
- Venlafaxine 1
Tricyclic Antidepressant:
- Amitriptyline 30-150 mg/day 1, 4
- Particularly effective for patients with mixed migraine and tension-type headache, or comorbid depression/anxiety 4
Implementation Strategy
Start low, titrate slowly:
- Begin at low dose and gradually increase until clinical benefits achieved or side effects limit further increases 4
- Allow adequate trial period of 2-3 months at therapeutic dose before determining efficacy 1, 4
- Use headache diaries to track attack frequency, severity, duration, and disability 4
Duration of therapy:
- Consider pausing preventive treatment after 6-12 months of successful control to determine if therapy can be discontinued 1, 4
- Useful measure: calculate percentage reduction in monthly migraine days 4
Second-Line Preventive Medications
Use when first-line agents fail or are contraindicated:
- Flunarizine 5-10 mg once daily (where available; avoid in Parkinsonism or depression) 4
- Sodium valproate 800-1500 mg/day or divalproex sodium 500-1500 mg/day 4
Third-Line: CGRP Monoclonal Antibodies
Consider when 2-3 oral preventive medications have failed or are contraindicated:
- Erenumab 70 or 140 mg subcutaneous once monthly 1, 4, 6
- Fremanezumab 225 mg subcutaneous once monthly or 675 mg quarterly 1, 4
- Galcanezumab subcutaneous once monthly 1, 4
- Eptinezumab 100 or 300 mg IV quarterly 1, 4
Important considerations:
- Assess efficacy only after 3-6 months (longer than oral agents) 1, 4
- Significantly more expensive than oral agents: $5,000-$6,000 annually 4
- No vasoconstriction, safe for patients with cardiovascular disease 4
Fourth-Line: OnabotulinumtoxinA
For chronic migraine ONLY (≥15 headache days/month with ≥8 migraine days):
- OnabotulinumtoxinA 155-195 units to 31-39 sites every 12 weeks 5, 4
- FDA-approved for chronic migraine prophylaxis 5
- Specifically NOT recommended for episodic migraine 4
- Assess efficacy after 6-9 months 4
Non-Pharmacological Adjuncts
Recommend alongside medication or as stand-alone when medications contraindicated:
- Cognitive behavioral therapy, biofeedback, relaxation training 4
- Neuromodulatory devices 4
- Acupuncture (though not superior to sham acupuncture in controlled trials) 4
- Lifestyle modifications: regular sleep, hydration, regular meals, stress management, regular exercise 1, 4
Special Populations
Children and Adolescents
Acute Treatment:
- Ibuprofen as first-line for pain 1
- In adolescents, consider: sumatriptan/naproxen oral, zolmitriptan nasal, sumatriptan nasal, rizatriptan ODT, or almotriptan oral 1
- If one triptan ineffective, try another or NSAID-triptan combination 1
- Add antiemetic for nausea/vomiting 1
Preventive Treatment:
- Discuss with families that placebo was as effective as studied medications in many pediatric trials 1
- Evidence for: amitriptyline combined with cognitive behavioral therapy, topiramate, propranolol 1
- Topiramate and valproate are teratogenic: advise effective birth control and folate supplementation 1
Pregnancy and Lactation
Discuss adverse effects of pharmacologic treatments during pregnancy and lactation before initiating therapy 1
- Valproate is strictly contraindicated due to teratogenic effects 1, 4
- Topiramate requires effective birth control and folate supplementation 1, 4
Critical Pitfalls to Avoid
Medication-Overuse Headache:
- Most common pitfall: allowing patients to increase frequency of acute medication use in response to treatment failure 2
- This creates a vicious cycle leading to daily headaches 1, 2
- Strict limit: no more than 2 days per week for ALL acute medications 1, 2
Inadequate Trial Duration:
- Oral preventives require 2-3 months at therapeutic dose 1, 4
- CGRP monoclonal antibodies require 3-6 months 1, 4
- OnabotulinumtoxinA requires 6-9 months 4
- Do not abandon treatment prematurely 4
Starting Dose Too High:
Failing to Recognize Contraindications:
- Screen for cardiovascular disease before prescribing triptans or ergots 2
- Screen for depression and Parkinsonism before prescribing flunarizine 4
- Verify pregnancy status before prescribing valproate or topiramate 1, 4
Not Counseling on Early Treatment:
- Triptans are most effective when taken early while pain is still mild 1, 2
- Delayed treatment reduces efficacy significantly 1
