Safety Profile and Concerns

• The most common side effects include neurological, cardiovascular, and gastrointestinal disturbances, which are typically dose-related 2

Efficacy in Children

Research on dextromethorphan's efficacy in children shows:

• A recent study (2023) demonstrated that dextromethorphan reduced cough frequency during daytime by 25.5% compared to placebo in children aged 6-11 years with acute cough due to common cold 4
• Some studies suggest a potential dose-response relationship, with doses around 0.5 mg/kg potentially balancing symptomatic relief with minimizing adverse events 5

Important Precautions

• Never exceed the recommended dose for the child's age group
• Do not administer to children under 4 years of age under any circumstances 1
• Avoid prolonged use without medical supervision
• Discontinue use and seek medical attention if symptoms worsen or persist beyond a few days

Common Pitfalls to Avoid

1. Using adult formulations or doses for children
2. Using household spoons instead of the provided measuring device
3. Administering to children under 4 years of age
