Caution with Zeet Syrup: For a 1.5-year-old child, medications like Zeet Syrup, containing diphenhydramine, ammonium chloride, and sodium citrate, should be used with caution.

Diphenhydramine: This antihistamine can cause drowsiness and is generally not recommended for very young children without medical supervision.

Ammonium Chloride and Sodium Citrate: These ingredients help with mucus but require careful dosing in toddlers.

Recommendation: Consult your pediatrician before administering this syrup. They can provide guidance tailored to your child's needs and suggest safer alternatives.

Supportive Care: Ensure your child stays hydrated and monitor for any worsening symptoms like difficulty breathing or high fever, which need prompt medical attention.
