If you have an itchy throat or cough and can’t sleep, you often have symptoms caused by laryngitis and need to treat the symptoms of laryngitis. If the cough is more severe, you need to take cough medicine to relieve phlegm. In the case of dry cough, it is recommended to take compound licorice combination or fenagan syrup for cough relief. For cough with phlegm, it is recommended to take Ambrotero Oral Solution or Ambroxol Hydrochloride or Pulmonary Cough Combination to relieve the symptoms. If the symptoms are not relieved by taking the above drugs, it is likely that a bacterial infection is combined and antibiotics are needed for treatment. If there is no allergy to penicillin, you can take amoxicillin or amoxicillin clavulanate potassium for anti-inflammation. If there is an allergy to penicillin, treatment can be switched to azithromycin.
