For children with dry cough, the first thing you can do is to give your child more warm water to lubricate the child’s airways and improve the symptoms of dry cough. If the dry cough is caused by other allergic factors, such as eczema, diarrhea and other allergic manifestations when the child was a child, the child should be given anti-allergic treatment in a timely manner, and it is recommended to use loratadine syrup and cetirizine syrup. In addition, if the symptoms are more serious, glucocorticoids should be added for anti-allergic treatment. Secondly, if the child has a dry cough and the blood test is positive for mycoplasma antibodies, it is time to consider that the child’s dry cough is caused by mycoplasma infection. For mycoplasma pneumoniae infection in children, macrolides are usually used for treatment, and commonly used macrolides include erythromycin, roxithromycin, azithromycin, etc.
