Is a 41-year-old woman with infrequent migraines (2 days/month), lasting 48-72 hours, and partial relief with acute treatment, eligible for preventive treatment given the impact on her productivity?

Preventive Migraine Treatment Eligibility

Given the migraine frequency and impact on productivity, preventive treatment should be offered to this patient. 1

Assessment of Preventive Treatment Eligibility

This 41-year-old woman presents with several key factors that make her an appropriate candidate for preventive migraine therapy:

1. Duration of attacks: Her migraines last 48-72 hours, which is significant and disabling
2. Impact on productivity: She is concerned about missing time from work routinely
3. Incomplete response to acute treatment: She has only partial relief with current acute treatment

The American College of Physicians and American Headache Society guidelines indicate that preventive therapy should be considered when:

• Migraine attacks produce disability lasting 3 or more days per month 2
• There is significant impact on quality of life and productivity 1
• Acute treatments provide only partial relief 1

While her migraine frequency (2 days/month) is lower than some traditional thresholds, the extended duration (48-72 hours per attack) means she experiences migraine symptoms for 4-6 days monthly, which significantly impacts her work productivity.

Preventive Treatment Options

If preventive treatment is initiated, evidence-based options include:

• First-line options 1:

  • Beta-blockers: Propranolol (80-240 mg/day) or Timolol (20-30 mg/day)
  • Anticonvulsants: Topiramate (100 mg/day) or Divalproex sodium (500-1500 mg/day)
  • Tricyclic antidepressants: Amitriptyline (30-150 mg/day)

• Alternative options 1, 2:

  • Angiotensin receptor blockers: Candesartan or Telmisartan
  • CGRP antagonists (gepants): Atogepant or Rimegepant
  • CGRP monoclonal antibodies: Eptinezumab, Erenumab, Fremanezumab, or Galcanezumab

Optimizing Current Treatment Approach

While preventive treatment is appropriate, it's also important to:

1. Evaluate current acute treatment: Although she reports partial relief with her current acute medication, optimization could still be beneficial alongside preventive therapy

2. Consider a headache diary: To track frequency, severity, and medication use 1

3. Assess for medication overuse: Ensure she isn't using acute medications more than twice weekly, which could lead to medication overuse headache 2, 1

Follow-up Recommendations

• Effectiveness of preventive treatment should be assessed after 6-8 weeks at therapeutic doses 1
• Regular follow-up appointments to monitor progress and adjust treatment as needed
• Consider referral to headache specialist if preventive treatments fail 1

Important Considerations

• Medication selection: Should consider comorbidities, side effect profiles, and patient preferences 1, 3
• Realistic expectations: Preventive medications typically aim to reduce frequency and severity by ≥50%, not eliminate attacks completely
• Duration of therapy: Preventive medications typically require 6-8 weeks at therapeutic doses before effectiveness can be properly assessed 1, 4

The evidence clearly supports offering preventive treatment to this patient given her prolonged attack duration and impact on work productivity, even though her attack frequency is relatively low.
