What is brompheniramine/dextromethorphan/pseudoephedrine?
Brompheniramine/dextromethorphan/pseudoephedrine is a combination medicine used to ease common upper respiratory symptoms. It brings together three active ingredients with different roles:
- Brompheniramine — an antihistamine.
- Dextromethorphan — a cough suppressant.
- Pseudoephedrine — a decongestant.
Because it combines several ingredients, it may help with more than one symptom at the same time. However, it does not cure infections or remove the cause of the symptoms.
What is it used for?
This combination is commonly used for temporary relief of symptoms linked to colds or allergies, including:
- Nasal congestion
- Cough
- Sneezing
- Runny nose
It is often discussed in relation to products such as Bromfed DM, which use this type of ingredient combination for upper respiratory symptom relief.
How does each ingredient work?
Brompheniramine
Brompheniramine is an antihistamine. In this combination, it helps reduce allergy-type symptoms such as sneezing and runny nose.
Dextromethorphan
Dextromethorphan is a cough suppressant. It is used to help reduce coughing.
Pseudoephedrine
Pseudoephedrine is a decongestant. It helps relieve nasal stuffiness and congestion.
Dosage and use
Dosage depends on the exact product, strength, and whether it is a tablet or liquid. The original package directions or official leaflet should always be followed.
General points to verify before use include:
- The exact strength of each ingredient
- The dosing interval listed on the label
- The maximum amount allowed in 24 hours

To reduce risk, make sure a pharmacist or doctor knows about all prescription medicines, over-the-counter products, and supplements you use.
