yes those medications are compatible but mucinex dm may not quiet his cough as much as you think. the "dm" part is dextromethorophan which is a cough suppressant but the mucous-thinning aspect of the mucinex may cause more drainage; thus triggering more coughing. this doesn't happen to everyone but in some people it does. taking a pure cough suppressant just at night will help him but when you have pneumonia you need to cough periodically to clear your airway. if he was properly diagnosed he should be feeling fine soon.
can mucinex dm and z-pack be taken together? . my son a college freshman likely has walking pneumonia. today his second trip to the health center in a week he was prescribed a z-pack for his symptoms: hacking cough fatigue fever and chills. his cough sounds alarming over the phone and is preventing him from getting much sleep. can he take mucinex dm to suppress his cough so he can sleep/rest?
