I have been using Mucinex Dm tablets for a chronic post nasal drip that turns into a bronchial infection quite often. Now I am being sent to an allergist to do some testing to see if my problem might be caused by an allergy to something & they have told me to stop using all antihistamines 1 week before the allergy test. Can u please tell me if Mucinex Dm contains antihistamine? Thank you, YYYY@YYYY WHY DON T YOU WARN FOLKS THAT USING THIS SERVICE IS NOT FREE BEFORE THEY TYPE THEIR QUESTION?!?! PLEASE CANCEL MY REQUEST

Is Mucinex DM An Antihistamine?
Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Mucinex Dm tablets do not contain antihistamine. It is a combination of cough suppressant and mucus thinner. This can be taken prior to allergy test. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Harsha D S
