Treatment of Headache Syndrome
For patients with migraine-type headache syndrome, initiate acute treatment with combination therapy of a triptan plus an NSAID or acetaminophen, and strongly consider preventive medication (propranolol, topiramate, or candesartan) if headaches occur ≥2 days per month with significant disability. 1, 2
Initial Assessment and Classification
The critical first step is determining whether the headache is primary (migraine, tension-type, cluster) or secondary to an underlying condition. Look specifically for red-flag features including: 3, 4
- Thunderclap onset (sudden, severe, "worst headache of life") suggesting subarachnoid hemorrhage 5, 4
- Age >50 years with new-onset headache requiring ESR/CRP to exclude temporal arteritis 6, 5
- Neurologic deficits on examination mandating immediate neuroimaging 5, 3
- Headache worsening with Valsalva or positional changes suggesting increased intracranial pressure 4
- Morning headaches resolving within hours suggesting obstructive sleep apnea 6
If any red flags are present, obtain urgent neuroimaging (MRI preferred over CT) and appropriate laboratory studies before initiating treatment. 6, 5
Acute Treatment Strategy
First-Line Acute Treatment
For moderate to severe migraine attacks, combination therapy is superior to monotherapy and should be initiated as soon as possible after headache onset: 1
- Triptan (sumatriptan 50-100 mg, rizatriptan, or eletriptan) PLUS NSAID (ibuprofen 400-800 mg or naproxen 500-1000 mg) or acetaminophen 1
- Add an antiemetic with prokinetic properties (metoclopramide) if nausea is prominent 1
- Triptans eliminate pain at 2 hours in 20-30% of patients but cause transient flushing, tightness, or tingling in 25% 7, 3
Critical contraindications for triptans include: uncontrolled hypertension, coronary artery disease, Prinzmetal's angina, stroke/TIA history, hemiplegic or basilar migraine, and Wolff-Parkinson-White syndrome 1, 7
For Mild Migraine
Start with NSAID monotherapy (ibuprofen, naproxen, or aspirin) or the combination of acetaminophen-aspirin-caffeine. 1 Acetaminophen alone is ineffective for migraine. 1
Second-Line Acute Options
If triptans fail or are contraindicated, consider CGRP antagonists (gepants: rimegepant 75 mg, ubrogepant 50-100 mg, or zavegepant nasal spray). 1 These eliminate headache at 2 hours in approximately 20% of patients with adverse effects of nausea and dry mouth in 1-4%. 3
Lasmiditan (5-HT1F agonist) is reserved for patients who fail all other treatments and is safe in those with cardiovascular risk factors, unlike triptans. 1, 3
Critical Medication Overuse Warning
Never use opioids or butalbital-containing compounds for migraine treatment. 1 These medications lead to medication overuse headache (MOH) and worsen the overall headache burden. 1, 7
Limit acute medication use to prevent MOH: 1
- Triptans: ≤10 days per month
- NSAIDs: ≤15 days per month
- Any acute medication: avoid use >2 days per week
Preventive Treatment Strategy
Indications for Preventive Therapy
Initiate preventive treatment if any of the following apply: 2
- Headaches occurring ≥2 days per month causing disability for ≥3 days per month 1, 2
- Using acute medications >2 days per week or approaching medication overuse thresholds 1, 2
- Failure of or contraindications to acute treatments 1, 2
- Patient preference to reduce attack frequency 1
First-Line Preventive Medications
Choose from these evidence-based first-line agents: 1, 2
- Propranolol 80-240 mg/day (or alternative beta-blockers: metoprolol, atenolol, bisoprolol, timolol 20-30 mg/day) 1, 2
- Topiramate 50-100 mg/day (particularly beneficial in patients with obesity due to weight loss effects) 1, 2
- Candesartan 16 mg/day (especially useful with comorbid hypertension) 1, 2
Start at low doses and titrate slowly over 2-3 months to assess efficacy and tolerability. 2 An adequate trial requires 2-3 months before determining effectiveness. 1, 2
Second-Line Preventive Medications
If first-line agents fail or are not tolerated: 1, 2
- Amitriptyline 30-150 mg/day (optimal for comorbid depression, anxiety, or mixed migraine/tension-type headache) 1, 2
- Flunarizine 5-10 mg/day at night (effective but monitor for sedation, weight gain, depression, and extrapyramidal symptoms; avoid in elderly and those with Parkinson's disease) 2
- Sodium valproate 800-1500 mg/day or divalproex sodium 500-1500 mg/day (STRICTLY CONTRAINDICATED in women of childbearing potential due to teratogenic effects) 1, 2
Third-Line: CGRP Monoclonal Antibodies
Consider CGRP monoclonal antibodies (erenumab, fremanezumab, galcanezumab, or eptinezumab) only after failure of 2-3 oral preventive medications. 1, 2 These require subcutaneous injection monthly and cost $5,000-6,000 annually. 2 Allow 3-6 months to assess efficacy. 2
Lifestyle Modifications and Non-Pharmacological Approaches
Implement these evidence-based lifestyle strategies alongside medication: 1
- Sleep hygiene: consistent sleep schedule with 7-8 hours nightly 1
- Regular meals and hydration: avoid skipping meals, limit caffeine intake 1
- Regular aerobic exercise: moderate to intense physical activity 1
- Stress management: cognitive-behavioral therapy, biofeedback, mindfulness, or relaxation training 1, 2
- Trigger identification and avoidance: use headache diaries to track patterns 2
Consider neuromodulatory devices or acupuncture as adjuncts when medications are contraindicated, though evidence for physical therapy and dietary approaches is limited. 1, 2
Management of Medication Overuse Headache
If MOH is present (headache ≥15 days/month for ≥3 months with overuse of acute medications): 1
- Abruptly stop non-opioid analgesics and triptans (or taper within 1 month) 1
- Gradually withdraw opioids over ≥1 month if present 1
- Initiate preventive therapy early as MOH prevents effectiveness of preventive treatments 1
- Expect transient worsening of headache during withdrawal 1
Headache-Specific Considerations
For IIH-Associated Headache
Tailor treatment to the headache phenotype (68% have migrainous features). 1 Use migraine-specific therapies as above, with these additions: 1
- Short-term NSAIDs or acetaminophen in first weeks (indomethacin may have advantage due to ICP-lowering effects) 1
- Avoid opioids completely 1
- Acetazolamide treats papilledema but NOT headache alone 1
- Lumbar punctures are not recommended for headache treatment 1
For Tension-Type Headache
Acute treatment: NSAIDs 8 Preventive treatment: Tricyclic antidepressants (amitriptyline) 8
For Cluster Headache and Trigeminal Autonomic Cephalalgias
Acute treatment requires specific approaches beyond standard migraine therapy (high-flow oxygen, subcutaneous sumatriptan). 8 Indomethacin is often effective for paroxysmal hemicrania. 8
Common Pitfalls to Avoid
- Failing to recognize medication overuse headache before starting preventive therapy 2
- Inadequate trial duration (<2-3 months) before declaring preventive treatment ineffective 2
- Starting preventive medications at too high a dose leading to poor tolerability and discontinuation 2
- Using triptans in patients with cardiovascular disease or risk factors without proper evaluation 7
- Prescribing valproate to women of childbearing potential 1, 2
- Missing secondary headache causes in patients >50 years with new-onset headache 6, 5
Duration and Reassessment
After 6-12 months of successful preventive therapy, consider tapering to determine if treatment can be discontinued. 2 Use headache diaries to calculate percentage reduction in monthly migraine days as a measure of success. 2
