What medicine is good for itchy throat, cough with phlegm?

Itching in the throat accompanied by cough and phlegm can be managed with antitussives and expectorants, antihistamines, leukotriene modifiers, traditional Chinese medicines (TCM), or local treatments. The choice should be based on underlying causes such as allergies or infections to ensure targeted therapy and avoid indiscriminate medication use. If symptoms persist for more than one week or are accompanied by fever or difficulty breathing, prompt medical attention is recommended.

1. Antitussives and expectorants: These are categorized into centrally-acting and peripherally-acting antitussives, many of which also have expectorant effects. They help suppress the cough reflex, thin mucus, and promote its expulsion. They are suitable for cases with excessive phlegm and frequent coughing that interferes with rest. Dosage should be adjusted according to age.

2. Antihistamines: Used for throat itching and irritative cough caused by allergies, these drugs block histamine receptors to reduce mucosal allergic reactions, thereby relieving itching and dry cough. Some formulations may cause drowsiness; therefore, driving or operating machinery should be avoided after taking them.

3. Leukotriene modifiers: Suitable for cough with phlegm associated with allergic pharyngitis or asthma, these agents inhibit the release of inflammatory mediators, reduce airway hyperresponsiveness, and improve symptoms of throat itching and sputum production. They should be taken according to a physician's instructions and for the prescribed duration.

4. Traditional Chinese medicine (TCM): Formulations with effects of dispelling wind, clearing heat, moistening the lungs, and resolving phlegm—such as Chuanbei Pipa Syrup or Jizhi Syrup—can alleviate throat discomfort and cough with phlegm. They are appropriate for individuals with mild symptoms or those who cannot take Western medications.

5. Local treatments: Gargling solutions help cleanse the throat mucosa and relieve itching, while throat lozenges soothe dryness and irritation. These local measures can assist in reducing cough and work better when combined with oral medications.

In daily life, drink plenty of warm water to keep the throat moist, avoid spicy, raw, cold, greasy foods, and exposure to smoke, dust, and other irritants. Reduce voice use, ensure adequate sleep, and consume lung-moistening foods such as pears and tremella mushrooms to support symptom recovery.
