Generally speaking, coughing plays an important role in clearing irritants and infections from the body. The best treatment for cough depends on the underlying cause of its production, and there are many possible causes of cough, including allergies, infections and acid reflux. For severe cough, the following treatments can be used: First, you can apply Asmac treatment, which is a combination of medications for allergies, cough suppressants, and phlegm-suppressing medications that are effective in treating cough. Secondly, N-acetylcysteine can be taken under the guidance of a doctor. It can effectively reduce mucus in the airways and make phlegm easier to cough up in order to reduce the frequency and severity of wet cough. Third, if it is a dry cough, you can take central cough suppressants orally to cut off the cough reflex, which has a good cough suppressing effect. Fourth, if the cough is caused by an infection, you need to choose the appropriate medication according to the specific pathogen to clear the infection and eliminate the cause of the cough from the root. Fifth, if the cough is caused by gastroesophageal reflux, it is recommended to take oral acid-suppressing drugs, such as omeprazole, and oral gastrodynamic drugs, such as morpholine, at the same time to achieve the treatment purpose. Sixth, if the cough is caused by allergies, you may need to inhale hormonal drugs under the guidance of your doctor.
