What should I do for cough with yellow phlegm and yellow nasal discharge?

Cough with yellow phlegm and yellow nasal discharge usually requires targeted treatment depending on the underlying cause. Common causes include acute rhinitis, acute sinusitis, and bacterial infection complicating the common cold. Specific analyses are as follows:

1. Acute Rhinitis

Cough with yellow phlegm and thick yellow nasal discharge may result from acute inflammation of the nasal mucosa, leading to acute rhinitis. It is generally recommended to avoid allergens, promptly clear nasal secretions, and take antihistamine medications such as cetirizine hydrochloride tablets, loratadine tablets, or ebastine tablets under medical guidance. These drugs help reduce histamine release and dilate small blood vessels in the nasal mucosa, thereby relieving symptoms. For severe nasal congestion, intranasal corticosteroids such as mometasone furoate nasal spray, budesonide inhalation suspension, or fluticasone propionate aerosol may also be used to reduce inflammation and promote recovery.

2. Acute Sinusitis

If acute purulent infection leads to acute sinusitis, it can easily cause symptoms such as yellow phlegm, prominent cough, and yellow nasal discharge. Healthcare professionals may use hypertonic saline or normal saline for nasal irrigation to help relieve nasal congestion. When bacterial infection is present, antibiotics such as amoxicillin capsules, ampicillin capsules, or amoxicillin-clavulanate potassium tablets may be prescribed to control the infection. For patients with more severe conditions, physical therapies such as ultrashort wave therapy or infrared radiation may be combined to promote resolution of inflammation and improve symptoms.

3. Common Cold Complicated by Bacterial Infection

Following a viral cold, when immunity is low and secondary bacterial infection occurs, symptoms such as cough, yellow phlegm, and yellow nasal discharge may develop. Under medical supervision, antibiotics such as cefixime capsules, cefotaxime capsules, or amoxicillin capsules are commonly used to eliminate pathogens and alleviate discomfort. Additionally, drinking plenty of water and maintaining a light diet can support symptom improvement.

In addition, these symptoms could also be caused by acute bronchitis. Seeking medical evaluation at a reputable hospital and receiving appropriate, cause-directed treatment can help relieve symptoms.
