What is the most effective way to treat cough with phlegm?

Coughing with phlegm is a common symptom of respiratory diseases. Effective treatment methods include:

1. Identifying the cause: Observe characteristics of the phlegm such as its color and consistency, for example yellow, white, or green phlegm. Laboratory tests may also be necessary, such as complete blood count, C-reactive protein, procalcitonin, Mycoplasma antibody tests, and chest X-rays.

2. Medication treatment: Antiviral drugs—if the phlegm is white and thin, this may indicate a viral infection, and medications such as Lanqin Oral Liquid, Pudilan tablets, or Feining Granules may be taken. Antibiotics—if the phlegm is yellow and thick, suggesting a bacterial infection, antibiotics such as Azithromycin may be prescribed. Expectorants—if there is excessive phlegm that is difficult to cough out, medications such as Ambroxol or Fudosteine may be used to help thin the phlegm and promote its expulsion. Antitussives—for severe coughing, antitussive medications such as Dextromethorphan or Compound Liquorice Tablets may be used. Medications should be used under a doctor's guidance.

3. Daily management: Drink plenty of water to help thin the phlegm and make it easier to expel. Eat more foods rich in vitamins and protein, and avoid spicy or cold foods. Maintain a good routine and engage in appropriate physical exercise.

4. Other considerations: For chronic cough with phlegm, treatment should target the underlying condition, such as managing asthma or quitting smoking.

If symptoms persist or worsen, seek medical attention promptly to avoid delaying treatment.
