What medicine works best for itchy throat, coughing, and phlegm?

Generally speaking, the throat refers to the pharynx. Itching in the throat and coughing with phlegm may be caused by poor environmental conditions, unhealthy eating habits, pharyngitis, bronchial asthma, chronic obstructive pulmonary disease (COPD), and other conditions. It is recommended to seek timely medical attention; under a doctor's guidance, treatment with medications such as Amoxicillin Capsules, Oseltamivir Phosphate Granules, Prednisone Acetate Tablets, Montelukast Sodium Tablets, and Salbutamol Sulfate Tablets may be effective. Detailed explanations are as follows:

1. Poor Environmental Conditions

Dry or heavily polluted air may cause dehydration of the pharyngeal mucosa, leading to local irritation and inflammatory reactions, causing patients to feel throat itching accompanied by mild coughing. Medication is generally not required; it is recommended to maintain an appropriate indoor humidity level, using humidifiers, and minimizing exposure to polluted environments.

2. Unhealthy Eating Habits

Consuming excessive spicy or greasy foods may increase gastric acid secretion, causing gastroesophageal reflux. When gastric acid flows back to the throat, it directly irritates the mucosa, possibly causing itching and reflexive coughing. Medication is generally unnecessary. Avoiding these foods in daily life, choosing bland and easily digestible meals, and avoiding eating within two hours before bedtime may help alleviate symptoms.

3. Pharyngitis

Pharyngitis is usually caused by bacterial or viral infections and is commonly seen in upper respiratory tract infections. Inflammation irritates the pharyngeal mucosa, causing throat itching, coughing, and increased phlegm production. It may also be accompanied by symptoms such as sore throat and a foreign body sensation. Patients may follow their doctor's advice to use medications such as Amoxicillin Capsules, Oseltamivir Phosphate Granules, and Pudilan Xiaoyan Oral Liquid.

4. Bronchial Asthma

Bronchial asthma is typically triggered by genetic factors, environmental pollution, or allergens. During an asthma attack, airway smooth muscle spasms and increased mucus secretion may cause symptoms such as difficulty breathing, wheezing, coughing, and expectoration. There may also be significant throat itching. Patients may use medications such as Salmeterol Fluticasone Inhalation Powder, Prednisone Acetate Tablets, and Montelukast Sodium Tablets under medical guidance.

5. Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease may result from long-term damage to airway epithelial cells due to smoking, occupational dust exposure, etc., leading to thickened airway walls, reduced elasticity, and irreversible airflow limitation. Patients often have large amounts of viscous secretions in their airways that are difficult to expel, thus frequently experiencing throat itching, coughing with phlegm, and possibly symptoms such as fatigue and leg swelling. Patients may follow medical instructions to use medications such as Ambroxol Hydrochloride Oral Solution, Acetylcysteine Effervescent Tablets, and Salbutamol Sulfate Tablets for treatment.

In daily life, maintaining humid indoor air is important to avoid excessive dryness aggravating throat discomfort. Humidifiers or placing water basins indoors can help increase air humidity.
