My mom is in the later stages of alzheimers. She was diagnosed with bronchitis 3 weeks ago. she is on her second round of z-;pack. she has been taking mucinex dm for the same 3 weeks. she is still coughing a lot at night, and more so during the day now. She is getting some of the junk out, but not always. My question is. Should I take her back to the ER (per doctor) or keep her comfortable and treat the symtoms?
