Prednisone Dosing for Bell's Palsy

The recommended dose of prednisone for Bell's palsy is 50 to 60 mg per day for five days followed by a five-day taper. 1

Medication Regimen Details

  • First-line treatment: Oral corticosteroids are strongly recommended for adult Bell's palsy with high-quality evidence showing significantly improved recovery rates with early steroid administration 2
  • Timing: Treatment should be initiated within 72 hours of symptom onset for maximum effectiveness 1, 3
  • Duration: 10-day course (5 days at full dose followed by 5-day taper) 1
  • Alternative dosing considerations:
    • Some older protocols suggested 1 mg/kg body weight up to 70-80 mg/day 4
    • Recent research suggests high-dose corticosteroids (≥80 mg) may provide better outcomes than standard doses (40-60 mg), with one meta-analysis showing decreased non-recovery rates at 6 months (OR = 0.17,95% CI = 0.05-0.56) 5

Treatment Efficacy

  • Prednisone significantly improves recovery rates:
    • At 3 months: 83.0% recovery with prednisone vs. 63.6% without (difference of +19.4%) 3
    • At 9 months: 94.4% recovery with prednisone vs. 81.6% without (difference of +12.8%) 3
    • Number needed to treat (NNT) for one additional complete recovery: 6 patients 3

Combination Therapy Considerations

  • Antivirals: While sometimes prescribed with steroids, evidence shows minimal additional benefit when combined with steroids 2
  • Antiviral options when considered:
    • Valacyclovir (1 g three times daily for 7 days) or
    • Acyclovir (400 mg five times daily for 10 days) 1
  • Antivirals alone are ineffective and not recommended 1

Important Clinical Considerations

  • Eye protection is crucial for patients with impaired eye closure:
    • Use artificial tears during the day
    • Apply lubricating ointment at night
    • Consider taping eyelids closed if necessary 2
  • Physical therapy may benefit patients with more severe paralysis 1
  • Early treatment accelerates recovery and may reduce time away from work 6

Monitoring and Follow-up

  • Monitor for potential adverse effects of high-dose steroids, including:
    • Elevated liver enzymes
    • Gastrointestinal issues 5
  • Refer to a facial nerve specialist if symptoms persist beyond 3 months, particularly for patients with dysphagia 2
