For example, if you have a dry cough, you can treat it with drugs such as cough bicarbonate and codeine phosphate oral solution. If there is phlegm that cannot be easily coughed out, it should be treated with cough and phlegm-relieving drugs such as carboxymethylstilbestrol and loquat, etc. Of course, the cough must be treated according to the cause. If it is a mycoplasma-chlamydia infection, you can use macrolide antibiotics such as achromycin. If it is an airway hyperresponsiveness, you can use paracetamol or loratadine. Coughing usually requires rest, ventilation of the living room, keeping the room quiet, fresh air and appropriate temperature and humidity. Eat a light diet, drink more water, eat more vegetables and fruits, eat more easily digestible liquid pasta, do not eat irritating, greasy or puffed food, and pay attention to hygiene in general.
