Understanding Promethazine DM Dosage Promethazine DM is a combination medication that includes promethazine, an antihistamine, and dextromethorphan, a cough suppressant. The dosage of Promethazine DM can vary depending on the individual's age, medical condition, and response to the medication. Adult Dosage For adults and children 12 years and older, the typical dosage of Promethazine DM is 30-60 mg of promethazine and 15-30 mg of dextromethorphan every 4-6 hours as needed. The maximum daily dose for promethazine is 180 mg/day [1]. Pediatric Dosage For children under 12 years, the dosage of Promethazine DM is based on the child's weight. The typical dosage is 5 mg/kg of promethazine and 2.5 mg/kg of dextromethorphan every 4-6 hours as needed. The maximum daily dose for promethazine is 30 mg/day [1]. Important Considerations When taking Promethazine DM, it's essential to follow the recommended dosage and not exceed the maximum daily dose. Taking more than the recommended dose can lead to increased side effects and potentially life-threatening complications. It's also important to note that Promethazine DM can interact with other medications, including opioids, tranquilizers, and barbiturates, which can increase the risk of side effects and overdose [2]. Side Effects and Precautions Common side effects of Promethazine DM include drowsiness, dizziness, nausea, vomiting, and headaches. More serious side effects can include respiratory depression, coma, and death, particularly in children [3]. As with any medication, it's crucial to discuss the potential risks and benefits with a healthcare professional before taking Promethazine DM, especially for children and individuals with underlying medical conditions.
