For what medicine to take for phlegm and sore throat, it first depends on what causes this symptom. If it is simply caused by inflammation in the throat, you can consider applying anti-inflammatory drugs, such as cephalosporin or azithromycin, for treatment. In addition, you can use phlegmolytic drugs, such as Ceno, Oronema or Mucosolvan. You can also apply throat-opening sword spray to spray your throat to relieve the symptoms if you relieve the symptoms of sore throat. If there is rhinitis or reflux esophagitis, it may also cause this condition because rhinitis may have nasal snot backing up into the throat and irritating the pharynx, causing phlegm and sore throat, therefore, the above condition can only be resolved after rhinitis is brought under control. In case of reflux esophagitis, stomach acid that flows back into the throat may irritate the pharynx and cause phlegm and sore throat, and medication for reflux esophagitis will also need to be applied to resolve these conditions.
