Promethazine dm ingredients?

What’s in Promethazine DM (promethazine + dextromethorphan)?

Promethazine DM is a cough medicine that combines two active ingredients: promethazine and dextromethorphan (usually labeled as “dextromethorphan HBr” on the product).

Because the exact formulation can vary by manufacturer and strength, the safest way to confirm the exact ingredients for the specific product you have is to check the “Active ingredient(s)” section on the bottle/box label.

What are the active ingredients used for?

• Promethazine: an antihistamine, used in this combination to help with cough-related symptoms and related nasal/throat irritation.
  
• Dextromethorphan: a cough suppressant, used to reduce the cough reflex.
  
  

What else is typically in the bottle besides the actives?

In addition to the active ingredients, cough syrups like Promethazine DM also include inactive ingredients (excipients) such as sweeteners, flavorings, colorants, buffers, preservatives, and the liquid base. Those inactive ingredients differ by brand and concentration.

If you tell me the exact product name (or share the strength, like “6.25 mg/15 mg per 5 mL” and whether it’s syrup), I can help you interpret the label to identify both the active and listed inactive ingredients.
