Safe Promethazine Dosage Guide for Adults and Children

People using promethazine should follow dosage instructions carefully and only take the amount prescribed by a healthcare professional. The medication is commonly used for allergy symptoms, nausea, motion sickness, and cough-related discomfort. However, using more than the recommended dose may increase the risk of dizziness, drowsiness, or breathing problems.

Doctors are often prescribed promethazine in doses ranging from 12.5mg to 25mg depending on the condition being treated. Children should only use promethazine under medical supervision because incorrect dosing may lead to serious side effects. Promethazine should never be used in children younger than 2 years old due to breathing risk warnings.
