There are many causes of coughing, so you need to find the cause and treat it accordingly. If you keep coughing, you need to take a chest X-ray to determine whether there are lung lesions. 1. If you have bronchitis or pneumonia, you can use antibiotics and cough suppressants to reduce phlegm. 2. If your child has a cough caused by pneumonia, you should avoid letting your child go to places with a lot of traffic, and you should wash your child’s hands regularly, change clothes regularly, and keep the air circulating in the room. Children are generally more energetic than adults, and they should not wear too thick clothes to avoid getting cold. 3. Sometimes laryngitis or pharyngitis can also lead to coughing. In this case, you need to go to the ear, nose and throat department for examination and use medication after diagnosis. 4. If the cough is caused by allergies, you need to stay away from allergens, inhale or take anti-allergic inflammatory drugs, and seek professional medical help so that the cough can be slowly controlled. The type of medication needed for treatment, the specific dosage and the method of use should be used under the guidance of a doctor to avoid harm to the body. If you keep coughing without relief, you need to actively search for the cause and then treat the cause.
