From the Guidelines

Loratadine is not recommended for a 9-month-old infant due to limited safety data and potential toxicity concerns. For a 9-month-old with allergy symptoms, it is essential to consult a pediatrician before giving any antihistamine medication, as most pediatric guidelines advise against using loratadine in children younger than 2 years, with some manufacturers specifically contraindicating use under 12 months 1. This restriction exists because infants metabolize medications differently than older children and adults.

Key Considerations

  • The efficacy of cold and cough medications, including loratadine, for symptomatic treatment of upper respiratory tract infections has not been established for children younger than 6 years 1.
  • There has been increasing concern over the safety of OTC cough and cold medications in children, with reports of fatalities associated with decongestants and antihistamines 1.
  • Second-generation antihistamines like loratadine have been shown to be well-tolerated and have a good safety profile in young children, but the data is limited for infants under 12 months 1.

Alternatives and Recommendations

  • Safer alternatives for a 9-month-old with allergy symptoms might include keeping the environment allergen-free, using saline nasal sprays, or a bulb syringe to clear nasal passages.
  • For severe symptoms, a doctor might recommend a different medication specifically approved for infants.
  • Always seek medical advice before giving any over-the-counter medication to an infant, as proper diagnosis is essential and dosing must be determined by a healthcare provider based on the child's specific condition and weight.

Additional Guidance

  • The FDA’s Nonprescription Drugs and Pediatric Advisory Committees have recommended that OTC medications used to treat cough and cold no longer be used for children below 6 years of age 1.
  • It is crucial to follow the guidance of pediatricians and healthcare providers when administering any medication to infants, given the potential risks and limited safety data 1.
