Cough Syrups Are Not Safe for Children Under 4 Years Old

Over-the-counter cough and cold medications should be avoided in all children below 6 years of age due to lack of proven efficacy and potential for serious toxicity, including fatalities. 1

The Evidence Against Cough Syrups in Young Children

Safety Concerns

  • Between 1969 and 2006, there were 54 deaths associated with decongestants (pseudoephedrine, phenylephrine, ephedrine) in children ≤6 years, with 43 deaths occurring in infants under 1 year. 1
  • During the same period, 69 deaths were linked to antihistamines (diphenhydramine, brompheniramine, chlorpheniramine) in the same age group, with 41 deaths in children under 2 years. 1
  • Common causes of these fatalities included medication errors, use of multiple products simultaneously, and accidental overdoses. 1

Lack of Efficacy

  • Controlled trials have demonstrated that antihistamine-decongestant combination products are not effective for upper respiratory tract infection symptoms in young children. 1
  • The efficacy of cough and cold medications has not been established for children younger than 6 years. 1

Regulatory Actions

  • In October 2007, major manufacturers (Wyeth, Novartis, Prestige Brands, Johnson & Johnson) voluntarily removed cough and cold medications for children under 2 years from the market. 1
  • The FDA's advisory committees recommended against using OTC cough and cold medications in children below 6 years of age. 1

What to Use Instead

For Dry Cough

  • Honey is the first-line treatment for acute cough in children over 1 year old, offering more relief than diphenhydramine or placebo. 2
  • Buckwheat honey specifically has evidence supporting its use in children. 3
  • Do not use honey in infants under 1 year due to botulism risk. 2

For Wet/Productive Cough

  • If the wet cough persists >4 weeks without specific concerning features (coughing with feeding, digital clubbing, growth failure), prescribe a 2-week course of antibiotics targeting common respiratory bacteria (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis), such as amoxicillin-clavulanate. 1, 2, 4
  • If cough resolves with antibiotics, the diagnosis is protracted bacterial bronchitis (PBB). 1, 2, 4
  • If cough persists after 2 weeks of antibiotics, prescribe an additional 2 weeks of appropriate antibiotics. 1, 2, 4

Critical Pitfalls to Avoid

  • Never use codeine-containing medications in children due to risk of serious respiratory distress. 2
  • Avoid all OTC cough suppressants in children under 6 years, as they are contraindicated and ineffective. 2, 5
  • Even FDA-labeled dextromethorphan products state "do not use" for children under 4 years of age. 6
  • Do not dismiss chronic wet cough as "just a cold"—persistent wet cough for >4 weeks requires active management to prevent progression to bronchiectasis. 4

Additional Supportive Measures

  • Eliminate environmental tobacco smoke exposure and advise cessation. 1, 2, 5
  • Vapor rub and nasal saline irrigation may provide symptomatic relief. 3
  • Address parental expectations and specific concerns about the cough. 1, 2
