Why do many physicians in India prescribe dexamethasone for fever and pain—is it because it provides rapid symptom relief?

Why Indian Physicians Prescribe Dexamethasone for Fever and Pain

Dexamethasone is being inappropriately prescribed for simple fever and pain in India because it provides rapid symptomatic relief, but this practice is not evidence-based and carries significant risks that outweigh any short-term benefits.

The Problem with This Practice

The widespread use of dexamethasone for routine fever and pain represents a fundamental misapplication of this potent corticosteroid. While dexamethasone does provide quick symptomatic relief through its anti-inflammatory and antipyretic mechanisms 1, this immediate gratification comes at a substantial cost to patient safety and does not address the underlying disease process.

Why It Provides "Instant Relief"

Dexamethasone works through multiple mechanisms to rapidly suppress symptoms:

• Antipyretic effect: It inhibits fever by blocking cytokine production (IL-6) and prostaglandin synthesis in both plasma and cerebrospinal fluid 1
• Anti-inflammatory action: As a synthetic glucocorticoid with 30 times the potency of cortisol, it powerfully suppresses inflammation 2, 3
• Pain reduction: It decreases inflammatory mediators that cause pain 4

This creates the illusion of effective treatment when, in reality, it merely masks symptoms while the underlying infection or condition persists untreated.

Evidence-Based Indications for Dexamethasone

Dexamethasone has specific, limited indications where benefits clearly outweigh risks:

1. COVID-19 with Hypoxemia (ONLY)

• Strong recommendation: Use dexamethasone 6 mg daily for up to 10 days in patients requiring supplemental oxygen, noninvasive ventilation, or mechanical ventilation 5
• Strong recommendation AGAINST: Do NOT use in COVID-19 patients not requiring oxygen—mortality actually increased (17.8% vs 14.0%) 5
• Extended duration beyond 10 days increases mortality 6

2. Bacterial Meningitis (Specific Pathogens)

• Recommended: 0.15 mg/kg every 6 hours for 2-4 days in adults with pneumococcal meningitis, started 10-20 minutes before or with first antibiotic dose 7
• Reduces: Hearing loss and neurologic sequelae in high-income countries with good medical care 8
• Stop immediately if pathogen is not H. influenzae or S. pneumoniae 8

3. Acute Pharyngitis (Marginal Benefit)

• Single-dose dexamethasone (8-10 mg) provides modest pain relief in bacterial pharyngitis 9, 10
• Effect size: 5.5 hours faster pain relief in streptococcal pharyngitis 11
• This marginal benefit does NOT justify routine use given the risks

Serious Risks of Inappropriate Use

The evidence clearly documents substantial harms from corticosteroid misuse:

Immediate Risks

• Impaired wound healing: Decreased inflammatory cell activation, reduced collagen synthesis 12
• Increased infection risk: Delayed viral clearance, secondary bacterial infections 12
• Gastrointestinal complications: Peptic ulceration, GI bleeding, perforation 12
• Hyperglycemia: Transient but significant blood sugar elevation 13, 3

Surgical Complications

• Significantly increased anastomotic leakage in patients on corticosteroids 12
• Wound infection and dehiscence 12

Long-term Consequences

• HPA axis suppression: Doses ≥15 mg/day prednisolone equivalent for >3 weeks cause inevitable adrenal suppression 14
• Rebound inflammation: Especially with abrupt discontinuation 13, 15
• Neuropsychiatric effects: Insomnia, mania, psychosis in predisposed individuals 13

Masking of Serious Disease

• Suppresses fever and inflammation that signal serious bacterial infections, malignancies, or other conditions requiring specific treatment
• Delays appropriate diagnosis and treatment of the actual underlying condition

The Correct Approach to Fever and Pain

For routine fever and pain management:

1. Identify the underlying cause through appropriate history, examination, and targeted investigations
2. Use appropriate first-line agents:
   • Acetaminophen (paracetamol) for fever and mild pain
   • NSAIDs (if not contraindicated) for inflammatory pain
   • Specific antibiotics for confirmed bacterial infections
3. Reserve dexamethasone exclusively for the evidence-based indications listed above

Why This Practice Persists in India

While not evidence-based, several factors drive this inappropriate prescribing pattern:

• Immediate patient satisfaction: Rapid symptom relief creates perception of effective treatment
• Pressure for quick results: Patients expect and demand fast relief
• Low cost and easy availability: Dexamethasone is inexpensive and widely accessible 13
• Lack of awareness: Many practitioners may not understand the risk-benefit profile
• Short-term thinking: Focus on immediate symptom control rather than long-term patient outcomes

Key Takeaway

The practice of prescribing dexamethasone for routine fever and pain is medically unjustified and potentially harmful. While it provides rapid symptomatic relief, this comes at the cost of masking underlying disease, increasing infection risk, impairing healing, and causing metabolic complications. Dexamethasone should be reserved exclusively for specific, evidence-based indications where mortality and morbidity benefits clearly outweigh these substantial risks 12, 5, 13.
