Key Takeaways
- Postnasal drip is commonly linked to conditions like allergies, viral infections such as the common cold and sinusitis.
- Nasal sprays can be a helpful solution, but only on a case-by-case basis, because sometimes they can make things worse.
- Lifestyle adjustments such as staying hydrated, focusing on sleep hygiene and using a humidifier can help reduce postnasal drip.
- If symptoms linger, worsen or are accompanied by fever, severe facial pain or thick green or yellow mucus, reach out to your PCP for treatment.
That constant, annoying feeling of mucus in your nose and throat can disrupt sleep, irritate the throat and trigger a cough.
While common, we don’t always know what causes postnasal drip, and some of its symptoms can overlap with other illnesses. Knowing what causes the issue can help you resolve it and get back to full strength.
What is postnasal drip?
Postnasal drip happens when excess mucus builds up in the nasal passages and drips down the back of the throat, according to the JAMA Network. The body naturally produces mucus to trap dust, allergens and other irritants, according to the National Institute of Health. But when production ramps up or thickens, it becomes noticeable.
People often experience postnasal drip alongside symptoms such as:
- Sore throat
- Bad breath
- Coughing, especially at night
- Feeling like you constantly need to clear your throat
Postnasal drip is commonly linked to conditions like allergies, viral infections such as the common cold and sinusitis. Seasonal changes in the weather, dry indoor air and spicy foods can contribute to the condition, per the Cleveland Clinic.
Postnasal drip is usually temporary, but it may linger in people with chronic sinus issues.
When should you use a nasal spray?
Nasal sprays can be helpful, but only on a case-by-case basis. Using the wrong type of spray – or using it too often – can make things worse. The JAMA Network states that lushing the nose with salt water or using medicated nasal sprays, such as steroid, antihistamine or anticholinergic sprays, can help.
Saline sprays are typically the safest starting point. They help moisten dry nasal passages and thin mucus, making it easier to clear. These can be used daily without much concern. Neti pots or squeeze bottles can flush out irritants and excess mucus but be sure to use sterile or distilled water to avoid bacteria.
Steroid nasal sprays – often recommended by health professionals for allergies – work by reducing inflammation in the nasal passages. They’re more effective for long-term control but may take several days to fully kick in.
Decongestant sprays are another option, but they should be used sparingly, usually no more than three days. Overuse can lead to rebound congestion, where symptoms come back worse than before.
If symptoms persist beyond 10 days or worsen, it may be time to check in with a health care provider to rule out infection or other underlying issues. Speak with your primary care provider (PCP) before attempting to eradicate symptoms of postnasal drip with a nasal spray.
How to stop postnasal drip
In addition to nasal sprays, here are other ways to stop that annoying drip. Lifestyle adjustments at home can make a big difference. A few practical strategies that can help reduce postnasal drip include:
- Stay hydrated: Drinking plenty of water and liquids like tea or broth can thin mucus, making it less sticky and easier to clear.
- Use a humidifier: Dry air can thicken mucus and irritate nasal passages. Adding moisture to the air, especially during colder months, can ease symptoms.
- Manage allergies: If allergies are the culprit, try minimizing your exposure to triggers like pollen, dust, pet dander, and ragweed. Antihistamines or prescribed treatments may also help.
- Elevate your head at night: Sleeping with the head slightly raised can prevent mucus from pooling in the throat, reducing nighttime coughing.
- Watch your diet, especially at night: If you have acid reflux, spicy, sour and fatty foods are not recommended before bedtime, per the JAMA Network, as they can make postnasal drip worse.
Postnasal drip is rarely serious, but it can be persistent. If symptoms linger, worsen or are accompanied by fever, severe facial pain or thick green or yellow mucus, it may signal a bacterial infection or another condition that requires you to reach out to your PCP for swift treatment.
