[|Human|] My dad is 82. He has allergies that cause lung problems and copd. He has congestive heart failure and afib. His pulmonologist told him to take Mucinex DM for a bronchial episode he had once and now dad takes it twice and day everyday and has been for months or years. Is this OK to take like that?
[|AI|]  HI, thanks for using Chat Doctor Murine Dm contains dextromethorphan and guaifenesin, a cough suppressant and bucolic. While long term use may not have any significant side effects, he should not need to use for this prolonged period. This is for short term use for acute cough/colds IF he is still congested and has a wet cough for months then that needs to be investigated and other causes, ruled out e.g. heart failure, lung disease hope this helps
