Always follow your doctor’s instructions precisely. The recommended Phenergan DM dosage varies significantly depending on your age, weight, and the specific condition being treated. Never exceed the prescribed dose.
For adults, a typical dose ranges from 12.5 to 50 mg every 4 to 6 hours, as needed for nighttime cough and cold symptoms. Children’s dosages are considerably lower and strictly weight-based.

Important Considerations: Avoid alcohol and other sedatives while taking Phenergan DM. This medication can cause drowsiness, so avoid operating machinery or driving after taking it.

Phenergan DM Dosage: A Detailed Guide
Always follow your doctor’s instructions precisely. A standard adult dose is typically 12.5 to 25 mg of promethazine every 4 to 6 hours as needed for nausea or vomiting, or 12.5 to 50 mg at bedtime for sleep. Children’s dosages vary significantly based on weight and age; consult your pediatrician for the correct amount.
The maximum daily dose for adults is 75 mg, but exceeding this should be avoided. Children’s maximum daily dosages are also weight-dependent and should be determined by a medical professional. Never give a child a dose intended for an adult.
Phenergan DM contains both promethazine and dextromethorphan. Dextromethorphan is a cough suppressant. The dosage of this component will be specified by your doctor, and may be different than the promethazine dose. Do not exceed the recommended dose of either medication.
Do not operate heavy machinery or drive after taking Phenergan DM, as drowsiness is a common side effect. Avoid alcohol consumption while using this medication. If you experience unusual side effects, such as severe drowsiness, difficulty breathing, or an allergic reaction, contact your doctor or seek immediate medical attention.

Understanding Phenergan DM and its Components
Phenergan DM combines two active ingredients: promethazine and dextromethorphan.
Promethazine is an antihistamine that effectively reduces nausea and vomiting. It also possesses sedative properties, contributing to its usefulness in managing symptoms like anxiety related to coughs.
Dextromethorphan acts as a cough suppressant, directly affecting the cough center in your brain. This helps control unproductive coughs, giving your body a chance to recover.
Understanding the roles of these components is key to using Phenergan DM appropriately. Remember to always follow your doctor’s instructions regarding dosage and frequency.
Always discuss potential interactions with other medications you’re taking with your healthcare provider before using Phenergan DM. This includes over-the-counter drugs and supplements.
Side effects can vary. Common ones include drowsiness, dizziness, and dry mouth. Consult your doctor if you experience concerning side effects or if symptoms persist.
Never exceed the recommended dosage. Incorrect usage can lead to unwanted and potentially harmful consequences.
Dosage Guidelines for Adults
For adults experiencing nighttime symptoms, the typical starting dose is 12.5 mg to 25 mg of promethazine with codeine (Phenergan DM) every 4 to 6 hours as needed. This dose can be increased to a maximum of 75 mg of promethazine per day, depending on your response and your doctor’s instructions.
Always follow your doctor’s prescription instructions carefully. Never exceed the prescribed dosage. If you experience any unexpected side effects, contact your doctor or pharmacist immediately.
For adults using Phenergan DM for nausea or vomiting, the dosage is typically 25 mg every 4 to 6 hours as needed. Again, do not surpass your doctor’s recommended maximum daily dose. The best approach is to start with the lowest effective dose and gradually increase only if necessary, under medical supervision.
Remember, individual responses to medication vary, and your doctor can adjust your dosage based on your specific needs and tolerance. Always discuss any concerns about medication with your healthcare provider before making changes to your dosage regimen.
Dosage Guidelines for Children
Always consult your child’s doctor before administering Phenergan DM. Dosage depends on your child’s weight and age. Never exceed the recommended dose.
| Weight Range (lbs) | Age Range (Years) | Dosage (mg/kg) per dose | Maximum Daily Dose (mg/kg) |
|---|---|---|---|
| 1-5 | 2-5 | 0.5 -1 | 3 |
| 6-11 | 6-12 | 0.5 – 1 | 3 |
| 12-17 | 12-17 | 1 -1.5 | 4.5 |
Administer Phenergan DM orally with food or milk to minimize stomach upset. Space doses evenly throughout the day. Observe your child for any side effects, such as drowsiness, dry mouth, or constipation. Report any concerns to your pediatrician immediately.
