Dry and itchy throat, cough and yellow sputum are mainly common due to bacterial invasion into the body and inflammatory reaction in the mucous membrane of the respiratory tract. Pay attention to keep warm and avoid getting cold. It can be treated with anti-bacterial drugs, such as antibiotics such as amoxicillin clavulanate potassium, cefoperazone sodium sulbactam sodium, ceftriaxone sodium, cefuroxime or azithromycin, roxithromycin, clarithromycin and quinolones, such as levofloxacin and fleroxacin. In addition, expectorant medications, such as orange-red phlegm cough liquid and amiloride syrup, can be taken appropriately. If necessary, take sputum for bacteriological culture and drug sensitivity test to clarify the cause of the disease and adjust the treatment plan at any time.
