What to do at 30-day follow-up for a patient on propranolol (40 mg QD) for migraine prevention?

Management of Propranolol for Migraine Prevention at 30-Day Follow-up

At the 30-day follow-up for this patient on propranolol 40 mg daily for migraine prevention, you should increase the dose to 80-160 mg daily as the current dose is subtherapeutic according to established guidelines. 1, 2

Dose Assessment and Adjustment

• The current dose of 40 mg daily is below the recommended therapeutic range for migraine prevention
• According to FDA labeling and clinical guidelines, the effective dose range for propranolol in migraine prophylaxis is 160-240 mg daily 2
• The American Academy of Neurology recommends propranolol at 80-240 mg/day as a first-line preventive medication 1

Recommended Dose Adjustment Plan:

1. Increase to 80 mg daily (minimum recommended starting dose) 1
2. If well tolerated but inadequate response after 2-3 weeks, consider further titration toward 160 mg daily
3. Maximum therapeutic dose for migraine prevention is 240 mg daily 1, 2

Effectiveness Evaluation

At this 30-day follow-up, assess:

• Headache frequency: Compare to baseline using patient's headache diary
• Headache severity: Evaluate intensity and duration of migraine attacks
• Functional impact: Assess disability related to migraines
• Medication adherence: Confirm consistent daily use
• Side effects: Monitor for common beta-blocker side effects (fatigue, dizziness, sleep disturbances)

Monitoring Parameters

• Vital signs: Check blood pressure and heart rate (propranolol can cause bradycardia and hypotension)
• Side effects: Assess for common adverse effects:
  • Fatigue or lethargy
  • Dizziness or lightheadedness
  • Sleep disturbances
  • Cold extremities
  • Depression or mood changes

Patient Education

• Explain that the current dose is lower than typically effective for migraine prevention
• Emphasize that full therapeutic effect may take 2-3 months at adequate dosing 1
• Reinforce the importance of maintaining a headache diary to track:
  • Frequency and severity of migraines
  • Potential triggers
  • Response to medication
  • Side effects

Follow-up Plan

• Schedule next follow-up in 4-6 weeks after dose adjustment
• Consider referral to neurology if:
  • No response after 2-3 months at therapeutic doses
  • Intolerable side effects preventing dose titration
  • Complicating comorbidities

Important Considerations

• While some patients may respond to lower doses (as low as 1 mg/kg daily) 3, most clinical evidence and guidelines support higher doses (80-240 mg daily) 1, 2
• If the patient experiences intolerable side effects with dose increases, consider alternative first-line preventive options such as topiramate, amitriptyline, or divalproex sodium 1
• Propranolol should not be abruptly discontinued; if treatment needs to be stopped, gradually taper the dose 2
