We often forget that coughing is a protective mechanism; it protects our lungs from mucous leaking down the wrong pipe.
However, if one needs cough
medicine (such as to allow for sleep
, ) one can take robitussin dm
at night only. Don't take more than instructed and see your doctor if the cough worsens, is associated with a fever
, or is not improving after a few days. Lots of water as well.
