Bromhexine Safety in a 12-Month-Old Child

Bromhexine should not be used routinely in a 12-month-old child due to concerns about potential adverse effects and lack of proven efficacy in the pediatric population, as recommended by the European Respiratory Society. 1

Guideline-Based Recommendations

The European Respiratory Society (ERS) 2021 guidelines explicitly address bromhexine use in children and adolescents with bronchiectasis:

  • The ERS suggests that bromhexine is not used routinely in children/adolescents (conditional recommendation, very low quality of evidence). 1
  • The guideline panel expressed concern that "most clinicians would be very concerned about using bromhexine due to the potential adverse effects." 1
  • This recommendation applies to the pediatric age range (0-18 years), which includes 12-month-old infants. 1

Evidence of Adverse Effects

The safety concerns are based on available clinical data:

  • Studies showed increased adverse events with bromhexine compared to placebo (OR 2.93,95% CI 0.12-73.97), though the confidence interval is wide due to small sample size. 1
  • The balance of evidence "favours not using bromhexine routinely based on patient/parents values, the substantial adverse effects described above and the lack of efficacy of these treatments." 1
  • Skin reactions have been documented with bromhexine use, including cases in children as young as 5 months, with reactions ranging from generalized urticaria to angioedema and anaphylactic reactions occurring within 1-30 days of starting treatment. 2

Key Clinical Considerations

Important caveats for this age group:

  • All available evidence comes from adult-based randomized controlled trials, with no pediatric-specific studies identified by the ERS systematic review. 1
  • The very low quality of evidence means there is substantial uncertainty about both efficacy and safety in children. 1
  • At 12 months of age, children have limited ability to cooperate with expectoration, making the theoretical benefit of a mucolytic agent questionable from a practical standpoint.

Alternative Approaches

For respiratory conditions requiring mucus management in a 12-month-old:

  • Airway clearance techniques are strongly recommended by the ERS for children with bronchiectasis, with individualized, age-appropriate methods taught by pediatric-trained physiotherapists. 1
  • These non-pharmacologic approaches avoid the adverse effect profile of mucolytic medications while providing proven benefit.

The clinical decision is clear: avoid routine bromhexine use in a 12-month-old child given the documented adverse effects, lack of pediatric efficacy data, and availability of safer alternatives for airway clearance. 1
