What to do if a four-year-old baby has a weakly positive Mycoplasma pneumoniae antibody and has a recurrent cough

Repeated cough with weakly positive antibodies to Mycoplasma pneumoniae in a four-year-old baby may be mycoplasma pneumonia and usually requires antibiotics to treat the infection and cough suppressants with phlegm suppressants.

1. Antibiotics: Macrolides, such as azithromycin, are preferred, which can effectively control Mycoplasma pneumoniae infection, but adverse reactions such as diarrhea, nausea, vomiting, and rash may occur, and azithromycin allergy is prohibited.

Tetracyclines (such as minocycline) are not recommended for four-year-olds because they may cause yellowing of teeth, and quinolone antibiotics (such as levofloxacin) are not recommended because they can affect bone development.

2. Cough and phlegm medicines: Cough suppressants are not recommended for babies with mild mycoplasma pneumonia because they will inhibit the discharge of sputum. When the cough is severe and accompanied by sputum, cough and phlegm drugs can be used, such as ambroterol oral liquid, but it may cause headache, dizziness, drowsiness, palpitation and other adverse reactions, and babies with hyperthyroidism, cardiac insufficiency, and renal insufficiency should be used with caution.

Medications must be used under the guidance of a doctor to avoid parents taking drugs blindly. In addition, in daily life, parents should encourage the baby to drink more water, pay attention to warmth, rest more, and eat lightly, which is also helpful for recovery. If the symptoms of cough do not relieve for a long time, it is recommended to go to the hospital for medical treatment in time.
