Bromfed Dosing for a 5-Year-Old
For a 5-year-old child, the recommended dose of Bromfed is 2.5 mL (½ teaspoonful) every 4 hours, not to exceed 6 doses in 24 hours. 1
FDA-Approved Dosing Guidelines
The FDA label for Bromfed provides clear age-based dosing for pediatric patients 1:
- Children 2 to under 6 years of age: 2.5 mL (½ teaspoonful) every 4 hours 1
- Children 6 to under 12 years of age: 5 mL (1 teaspoonful) every 4 hours 1
- Maximum daily doses: Do not exceed 6 doses during a 24-hour period 1
Since a 5-year-old falls within the 2 to under 6 years age range, the appropriate dose is 2.5 mL every 4 hours 1.
Important Clinical Considerations
Pharmacokinetic Profile in Children
Brompheniramine demonstrates effective H1-receptor blockade in children with a single 4 mg dose, producing prompt onset (within 0.5 hours) and sustained peripheral antihistamine effects lasting up to 30 hours. 2 The terminal elimination half-life in children averages 12.4 hours, with peak concentrations occurring around 3.2 hours after administration 2.
Safety Concerns
Exercise extreme caution with combination cold medications in young children, as fatal intoxications have been documented. 3 A case report documented fatal toxicity in an infant from a combination product containing pseudoephedrine, brompheniramine, and dextromethorphan, with postmortem brompheniramine blood concentrations of 0.40 mg/L 3.
Common Pitfalls to Avoid
- Never exceed the recommended dose or frequency - the 6-dose maximum per 24 hours must be strictly observed 1
- Do not use weight-based dosing - Bromfed dosing is age-based, not weight-based, per FDA labeling 1
- Monitor for anticholinergic side effects - brompheniramine commonly causes dry mouth, tiredness, and drowsiness in pediatric patients 4
- Avoid concurrent use of other antihistamines or decongestants to prevent overdosage 1
