Tonsillar Swelling Management

Introduction to Corticosteroid Therapy

The American Academy of Otolaryngology-Head and Neck Surgery recommends a dose of methylprednisolone 48 mg daily for 7-14 days, followed by a taper over a similar time period for tonsillar swelling 1
Methylprednisolone 48 mg daily is considered the standard dose for adults with tonsillar swelling, with a full dose for 7-14 days, then taper over a similar time period advised for effective management 1

For patients undergoing tonsillectomy, a single intraoperative dose of dexamethasone (equivalent to approximately 48 mg methylprednisolone) is strongly recommended to reduce post-operative pain, decrease time to first oral intake, and reduce nausea and vomiting 2

Methylprednisolone is 5 times more potent than hydrocortisone 1, 3
The equivalent dose relationships are important to understand: 48 mg methylprednisolone = 60 mg prednisone = 10 mg dexamethasone 1
Equivalent doses of common glucocorticoids are:
Glucocorticoid Equivalent Dose
Methylprednisolone 4 mg
Prednisone/Prednisolone 5 mg
Dexamethasone 0.75 mg
Hydrocortisone 20 mg

Short-term use (7-14 days) of methylprednisolone generally has acceptable and manageable adverse events 1
Underdosing with the commonly prescribed methylprednisolone dose pack provides inadequate total dosing for significant tonsillar swelling 1
Short-term side effects of corticosteroids include behavioral changes, gastrointestinal upset, sleep disturbances, and mood changes, with dose-dependent effects more common at higher doses, as reported by the American Academy of Allergy, Asthma, and Immunology 4
Repeated courses of oral corticosteroids can raise concerns about growth suppression, affecting linear growth in children, adrenal suppression, decreased bone mineral density, and metabolic effects, including weight gain and potential glucose metabolism issues, as highlighted by the American Academy of Allergy, Asthma, and Immunology and the American Thoracic Society/European Respiratory Society guidelines 4, 5

The following dosing regimens are suggested for methylprednisolone:

Population	Initial Dosing	Duration
Children	1-2 mg/kg/day (max 60 mg/day)	3-10 days
Adults	40-60 mg daily	3-10 days
Children (infrequent relapses)	60 mg/m² or 2 mg/kg/day	until remission for at least 3 days, then alternate-day dosing
Children (frequent relapses or steroid-dependent)	daily prednisone until remission for 3 days, then alternate-day prednisone	for at least 3 months

Adults should receive prednisone 40-80 mg/day in 1-2 divided doses until peak expiratory flow reaches 70% of predicted or personal best, with a total course of 5-10 days without the need for tapering, as recommended by the National Asthma Education and Prevention Program 7

Measure peak expiratory flow 15-30 minutes after starting treatment, and monitor vital signs, blood glucose, blood pressure, and electrolytes, as recommended by general medical practice and the American Academy of Allergy, Asthma, and Immunology 4
Patients with diabetes require strict blood glucose monitoring during treatment, with a 2-fold increase in blood glucose levels expected, peaking around 10 hours after each dose 8
Arrange follow-up within one week after completing treatment to assess recovery and adjust maintenance therapy if needed, as recommended by the American College of Rheumatology 8

Delaying corticosteroid administration can increase hospitalization risk 7
Using intravenous instead of oral administration has no advantage unless GI absorption is impaired 7
Unnecessary tapering is generally not required for short courses (≤10 days) of prednisone 7
Sedation is contraindicated in patients with acute asthma 9
Antibiotics should only be administered if a bacterial infection is present 9
Tofacitinib, filgotinib, upadacitinib, ozanimod, and etrasimod are contraindicated during conception, pregnancy, and lactation 10
The European Respiratory Society advises against offering corticosteroids to hospitalized patients with COVID-19 who do not require oxygen 11
Patients with major trauma should not receive corticosteroids 12
