Red flags & when to go in person for Postnasal Drip

Audience: adult

Postnasal drip occurs when excess mucus accumulates in the back of the nose and throat, causing discomfort such as throat clearing, coughing, or a sensation of mucus dripping. It often results from allergies, colds, or sinus infections and can usually be managed with home care or telemedicine consultations. However, some symptoms may indicate a more serious condition requiring in-person medical evaluation. Telemedicine can help assess symptoms, provide advice, and recommend treatments for mild to moderate cases. It is important to recognize red flags like high fever, difficulty breathing, or blood in mucus, which need urgent in-person care. Understanding when to seek face-to-face medical attention ensures timely and appropriate treatment for your health and safety.

What is Postnasal Drip?

Postnasal drip happens when extra mucus from your nose or sinuses drips down the back of your throat. This can cause throat irritation, coughing, or a feeling like you need to clear your throat often. It is a common symptom linked to colds, allergies, sinus infections, or irritants like smoke.

Common Causes and Symptoms

Postnasal drip is often caused by allergies, viral infections like the common cold, or sinus inflammation. Symptoms include a runny or stuffy nose, sore throat, cough, hoarseness, and sometimes bad breath. These symptoms usually develop gradually and can last for days to weeks.

When Telemedicine Can Help

Telemedicine is useful for evaluating mild to moderate symptoms of postnasal drip. A healthcare provider can review your symptoms, medical history, and suggest treatments such as nasal sprays, antihistamines, or home remedies. They can also advise when to monitor symptoms closely or seek in-person care.
