What is Promethazine DM?

Promethazine DM is a generic combination drug prescribed to relieve cough, runny nose, stuffy nose, sneezing, and other symptoms caused by the common cold or allergies. It is a prescription medicine that combines an antihistamine called promethazine with a cough suppressant called dextromethorphan.

Promethazine is an antihistamine that works by blocking the effects of histamine, a substance produced by the immune system in response to an allergen. Exposure to an allergen may cause symptoms such as runny nose, congestion, and sneezing.

Dextromethorphan is an opioid-like drug similar to codeine that calms the cough reflex. Unlike opioids, however, dextromethorphan does not relieve pain or produce other effects of opioids, making it a much safer drug for suppressing cough.

Promethazine DM is usually administered as one-half to one teaspoon of syrup once every four to six hours. The dosage can vary depending on an individual’s age, as children typically take a lower dose than adults. It’s important to follow the instructions and medical advice of a healthcare provider for the appropriate dosage to take. 

What are the side effects of Promethazine DM?

The most common side effects of Promethazine DM include, but are not limited to, drowsiness, dizziness, blurred vision, dry mouth, nausea, and vomiting. Consult a healthcare provider if these side effects persist or worsen.

Other side effects are possible, such as confusion, disorientation, sensitivity to light, fatigue, nervousness, euphoria, involuntary muscle movements, and hallucinations. Serious side effects may also include seizures, severe drowsiness, low blood pressure, breathing problems, and loss of consciousness.

Allergic reactions are rare but possible. Signs and symptoms of an allergic reaction include rash, swelling of the face or throat, and trouble breathing. Consult with your healthcare provider about possible side effects, warnings, and other information before using Promethazine DM.

Is Promethazine DM a controlled medication?

Promethazine DM is not considered a controlled substance in the United States. In other words, it is not classified by the Drug Enforcement Administration (DEA) as having a high potential for abuse or dependence. However, Promethazine DM is still a prescription medication and should only be used as directed by a healthcare provider.
