Brompheniramine: An Antihistamine at its Core
Brompheniramine is an antihistamine that helps alleviate allergy symptoms by blocking histamine. It does not contain opioids. Many over-the-counter cold and allergy medications contain brompheniramine along with other active ingredients. For example, Bromfed DM includes brompheniramine, pseudoephedrine, and dextromethorphan, and is codeine-free.
Codeine: The Opioid Cough Suppressant
Codeine is an opioid used to suppress coughs and relieve pain. It works by affecting the brain's cough reflex. As a controlled substance with potential for dependence, codeine requires a prescription.
Prescription Products Combining Brompheniramine and Codeine
Certain prescription medications combine brompheniramine and codeine for patients experiencing both allergy symptoms and persistent coughs. Examples include Bromphen-Pseudoephed-Codeine Liquid, Mesehist WC, Pluratuss, and Rydex, which often also contain a decongestant. Due to the codeine content, these products carry risks of opioid-related side effects like drowsiness, constipation, dependence, and abuse. Healthcare providers assess these risks before prescribing.
The Critical Distinction: Understanding OTC vs. Prescription
A key difference is that products containing codeine are prescription-only controlled substances, unlike most over-the-counter brompheniramine medications. OTC brompheniramine products provide allergy and cold relief without opioid risks. Combining any drowsy medication with alcohol or other CNS depressants is dangerous. Always check the product label and consult a pharmacist for clarification.

Conclusion: The Importance of Reading Your Label
The presence of codeine depends on the specific brompheniramine product. Pure brompheniramine and most OTC combinations do not contain codeine. However, certain prescription medications combine brompheniramine with codeine for allergy and cough relief. Always check the product label and consult a healthcare professional, especially for prescription drugs, to understand ingredients and risks. For more information, consult resources like the FDA.
