If the child has a cough caused by mycoplasma infection, he or she needs to take azithromycin, roxithromycin or clarithromycin. The cough medicine depends on the presence or absence of phlegm when coughing. If the cough is severe and dry, you can take a combination of forcodine or etanercept. If there is a lot of phlegm, you can take traditional Chinese medicine, such as pediatric asthma oral liquid, pediatric pulmonary cough granules, or lantern leaf granules, or pediatric cough and wheezing oral liquid, all of which have the effect of relieving cough and resolving phlegm. In addition, you can also give your child nebulized inhalation treatment, nebulized inhalation can be inhaled budesonide, salbutamol or terbutaline. Budesonide is a glucocorticoid that reduces local inflammation of the airways and also reduces airway hypersensitivity. Because bronchial infection by mycoplasma causes local airway hypersensitivity and epithelial cell damage, glucocorticoids can be used to repair it. Bronchodilators such as terbutaline and salbutamol can relieve airway spasm.
