How to treat postnasal drip

Postnasal drip—where mucus drains from the nasal passages into the throat—is a relatively common clinical phenomenon. Numerous conditions can cause this symptom, including chronic rhinitis, chronic sinusitis, fungal sinusitis, and postnasal drip syndrome. The most frequent causes are rhinitis and sinusitis. Additionally, other conditions such as pharyngitis may also contribute to postnasal drip. This condition significantly impacts patients’ daily lives, frequently causing rhinorrhea and pain localized to the nasal or sinus regions, sometimes accompanied by fever. So, how is postnasal drip treated? Below we address this question.

How to Treat Postnasal Drip

1. Symptom-Based Treatment

Treatment of postnasal drip must be tailored to its underlying cause. Patients are advised to undergo nasopharyngolaryngoscopy at a hospital to establish an accurate diagnosis, followed by targeted therapy. In most cases, postnasal drip syndrome is suspected, typically resulting from purulent secretions produced by pathological changes in the nasal cavity, sinuses, or nasopharynx, which subsequently irritate the pharynx. Common accompanying symptoms include nasal congestion, purulent rhinorrhea, and headache. Therefore, the primary treatment focus should be on addressing the underlying pathology in the nasal cavity, sinuses, and nasopharynx. Under physician guidance, oral antibiotics and intranasal fluticasone propionate (e.g., Flixonase®) spray may be prescribed. For symptomatic relief of the pharynx, lozenges such as Watermelon Frost Lozenges may be used.

2. Pharmacological Therapy

Pharmacotherapy is commonly employed for postnasal drip. If rhinitis is the cause—leading to excessive nasal discharge—heat-clearing and detoxifying medications may be selected. Oral amoxicillin dispersible tablets may also be prescribed for regulation. For conditions such as nasopharyngitis, throat-soothing tablets (e.g., Qingyan Tablets) or Huanglian Shangqing Tablets may provide symptomatic relief. In cases of purulent nasal discharge, anti-inflammatory agents such as clarithromycin or roxithromycin may be indicated. Additional adjunctive therapies include traditional Chinese patent medicines like Biyuan Tongqiao Granules.

The above outlines approaches to treating postnasal drip. Furthermore, during pharmacological treatment, patients should schedule regular follow-up visits to monitor therapeutic response. Some patients may also benefit from nasal irrigation using normal saline or isotonic seawater solutions, which serve as an effective adjunctive therapy. We hope this information proves helpful.
