Oct 29, 2025
A lingering scratchy throat or cough might not be just a cold or allergies—it could be postnasal drip. This common condition can feel anything but minor when it becomes chronic. We’ll explore what postnasal drip is, why it happens, and treatment options.

What Is Postnasal Drip and How Is It Treated?

Most of us have experienced a scratchy throat or a nagging cough at some point and blamed it on a cold or seasonal allergies. But what if that feeling lingers? You might be dealing with postnasal drip—a common condition that can feel anything but minor when it becomes chronic.

In this post, we’ll explore what postnasal drip is, why it happens, and the treatment options available to bring you relief.

What Is Postnasal Drip?

Postnasal drip occurs when excess mucus builds up in the nasal passages and drips down the back of the throat. Your body naturally produces mucus to trap dust, allergens, and microbes, and to keep the airways moist. But when your nasal passages produce too much mucus, or when the mucus becomes too thick, it can start to collect and drip—causing discomfort and various symptoms.

Common Symptoms of Postnasal Drip

  • Persistent throat clearing or cough
  • Tickling sensation in the throat
  • Sore throat or hoarseness
  • Bad breath (halitosis)
  • A sensation of mucus in the back of the throat
  • Nasal congestion or stuffiness

These symptoms can linger, especially if the underlying cause is not addressed.

What Causes Postnasal Drip?

Several conditions and environmental factors can lead to postnasal drip, including:

  1. Allergies (Allergic Rhinitis)

Seasonal or indoor allergies are a top cause. Pollen, dust mites, pet dander, and mold can trigger excessive mucus production.

  1. Colds and Respiratory Infections

Viral infections often lead to increased mucus, which continues even after other symptoms resolve.

  1. Sinusitis

Inflamed sinuses due to chronic or acute sinus infections can contribute to postnasal drainage.

  1. Weather and Dry Air

Cold or dry air can thicken mucus, making it harder to drain normally.

  1. Gastroesophageal Reflux Disease (GERD)

Acid reflux can irritate the throat and nasal passages, leading to mucus overproduction.

  1. Hormonal Changes and Medications

Certain medications and hormonal shifts (like pregnancy) can alter mucus production.

How Is Postnasal Drip Treated?

The key to treatment is identifying and addressing the underlying cause. Here are common approaches:

Oral medication, nasal sprays and/or treating the underlying cause.

When to See a Doctor

While postnasal drip is often a temporary nuisance, chronic or severe symptoms may indicate a deeper issue. Consult your healthcare provider if you experience:

  • Symptoms lasting more than 10 days
  • Frequent sore throats or difficulty swallowing
  • Foul-smelling mucus
  • Persistent sinus pain or pressure
