How much promethazine can your 16 month old take?

The dosage of promethazine for a 16-month-old should always be determined by a pediatrician, as it depends on the child's weight, medical condition, and overall health. Generally, promethazine is not recommended for children under 2 years of age due to the risk of severe side effects. It's crucial to consult a healthcare professional before administering any medication to ensure safety and proper dosing.
