What should I avoid while taking Bromfed DM?
Drinking alcohol can increase certain side effects of brompheniramine, dextromethorphan, and pseudoephedrine.
Ask a doctor or pharmacist before using any other cold, cough, allergy, or sleep medicine. Antihistamines and cough suppressants are contained in many combination medicines. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains an antihistamine or cough suppressant.
