How to treat cough with phlegm after a cold

Cough with phlegm after a cold can generally be improved through the use of anti-infective medications, expectorants, and nebulizer therapy.

1. Anti-infective Medications

Phlegm in the throat accompanied by persistent coughing after a cold may be caused by lower respiratory tract infection. In such cases, medications such as cefdinir dispersible tablets, cefuroxime axetil tablets, or cefaclor capsules may be used under medical guidance to reduce infection.

2. Expectorant Medications

Additionally, under a doctor's supervision, patients may take expectorant drugs such as ambroxol hydrochloride oral solution, bromhexine hydrochloride tablets, or acetylcysteine granules to facilitate the expulsion of phlegm.

3. Nebulizer Therapy

If the phlegm is particularly thick and difficult to cough up, doctors may recommend nebulized inhalation of budesonide suspension, terbutaline sulfate nebulizing solution, or acetylcysteine solution to reduce the viscosity of the mucus, making it easier to expel.

During treatment, it is also important to maintain a light diet and avoid spicy and irritating foods such as hot pot, chili peppers, etc., to prevent interference with recovery.
