When to Give Cough and Cold Medications to Children
Over-the-counter cough and cold medications should not be given to children under 4 years of age due to lack of proven efficacy and potential for serious adverse effects including death. 1, 2
Age-Based Recommendations
Children Under 4 Years
- Do not use OTC cough and cold medications 1, 2
- The FDA explicitly warns against using products containing antihistamines or decongestants in children younger than 2 years 3
- Major manufacturers voluntarily removed these products for children under 2 years from the market in 2007 4, 1
- FDA drug labels for dextromethorphan and diphenhydramine specifically state "do not use" for children under 4 years 5, 6
Children 4 to 6 Years
- Generally avoid OTC cold medications 1
- The FDA's Nonprescription Drugs and Pediatric Advisory Committees recommended against use in children under 6 years 4, 1
- Between 1969-2006, there were 54 deaths from decongestants and 69 deaths from antihistamines in children under 6 years, with the majority occurring in infants under 1 year 4, 1
Children 6 Years and Older
- May use OTC cold medications according to package directions, though benefits remain limited 1
- Dextromethorphan dosing: 5 mL every 12 hours for ages 6-12 years, not exceeding 10 mL in 24 hours 5
- Diphenhydramine dosing: 10 mL (25 mg) every 4-6 hours for ages 6-12 years 6
Why These Medications Should Be Avoided in Young Children
Lack of Efficacy
- Controlled trials demonstrate that antihistamine-decongestant combinations are not effective for upper respiratory tract infection symptoms in young children 4, 1
- Systematic reviews conclude OTC cough medications have little to no benefit in symptomatic control of acute cough in children 1, 7
- Dextromethorphan is no different than placebo in reducing nocturnal cough or sleep disturbance 7
Safety Concerns
- Common causes of adverse events include using multiple products containing the same ingredients, leading to unintentional overdose 4, 1
- Studies show 8-11% of children receive excessive doses 2
- OTC drugs are among the most common unintentional ingestion medications in children under 5 years 1, 2
- The overall adverse event rate is 0.573 cases per 1 million units sold, with accidental unsupervised ingestions accounting for 67.1% of cases 8
Safe Alternatives for Cough Management
First-Line Treatment
- Honey (for children over 12 months): Provides more relief than no treatment, diphenhydramine, or placebo 4, 7, 2
- Never give honey to infants under 12 months due to botulism risk 7, 2
Supportive Care
- Adequate hydration and environmental humidification help thin secretions 2
- Nasal saline irrigation can reduce symptom severity 9
- Vapor rub may improve symptoms 9
Medications to Strictly Avoid
- Codeine-containing medications: Risk of serious side effects including respiratory distress 4, 7, 2
- In 2018, FDA restricted prescription opioid cough medicines to adults 18 years and older 1, 2
When to Consider Specific Treatments
For Chronic Cough (>2-4 weeks)
- Re-evaluate for emergence of specific etiological pointers 4, 7
- If asthma risk factors are present: Consider a 2-4 week trial of inhaled corticosteroids (400 mg/day beclomethasone equivalent) 4, 7
- Always re-evaluate after treatment trial, as resolution may be spontaneous 7
For Suspected Bacterial Infection
- High fever (≥38.5°C) persisting >3 days: Consider beta-lactam antibiotics 7
- Persistent nasal discharge or confirmed sinusitis: 10-day antimicrobial course (though number needed to treat is 8) 7
- Acute cough from common colds: Antimicrobials provide no benefit 7
Common Pitfalls to Avoid
- Do not prescribe OTC medications due to parental pressure despite lack of efficacy 7, 2
- Do not assume all cough represents asthma and treat with bronchodilators without evidence of airflow obstruction 1, 7
- Do not use topical decongestants for more than 3 days due to risk of rhinitis medicamentosa (rebound congestion) 4
- Do not fail to re-evaluate children whose cough persists despite treatment 7
Second-Generation Antihistamines: The Exception
For allergic rhinitis (not acute cough/cold), second-generation antihistamines are safe in children 6 years and older:
