Post nasal drip happens when mucus from the nose and sinuses drains down the back of the throat. It can cause frequent throat clearing, coughing, irritation, a feeling of mucus in the throat, and sometimes a sore throat or bad breath.
Many cases improve with simple measures at home, but persistent or recurring post nasal drip may be related to allergies, sinus inflammation, reflux, infection, or another ENT condition.
Post nasal drip can feel different from person to person, but common symptoms include:
These symptoms can also occur with other conditions, so ongoing symptoms may need an evaluation to determine the underlying cause.
Post nasal drip is not a diagnosis by itself. It is a symptom that can develop for several different reasons.
Common causes include:
Because treatment depends on the cause, persistent symptoms should not always be treated the same way.
If your symptoms are mild, there are several simple measures that may help reduce throat irritation and make mucus easier to clear.
Drinking enough water can help keep mucus thinner and easier to clear.
Warm fluids may also feel soothing when post nasal drip is irritating the throat.
Saline can help moisturize the nasal passages and remove mucus, allergens, and irritants.
If you use a nasal rinse, follow the product instructions and use water that is appropriate for nasal irrigation.
Dry air can irritate the lining of the nose and throat. A clean humidifier may help add moisture to the air and make nasal irritation more comfortable.
Keeping your head and upper body slightly elevated may help reduce the feeling of mucus collecting in the throat while you sleep.

Warm salt water may help soothe throat irritation caused by drainage.
Tobacco smoke, vaping aerosols, strong fragrances, and other airborne irritants can worsen nasal and throat irritation.
If smoke seems to trigger your symptoms, read more about how smoking can affect the nose and sinuses.
Yes. Allergies can increase nasal inflammation and mucus production, which may lead to ongoing drainage down the back of the throat.
If your symptoms happen during certain seasons, around pets, dust, mold, or other triggers, allergies may be contributing.
Managing the allergy itself can be an important part of reducing post nasal drip.
Sinus inflammation can increase mucus production and affect how mucus drains through the nose.
People with recurring sinus pressure, congestion, or sinus infections may also experience frequent drainage into the throat.
If post nasal drip occurs along with facial pressure, nasal obstruction, or recurring sinus symptoms, an ENT evaluation may help identify whether a sinus condition is contributing.
Home care may be enough for mild symptoms, but persistent or recurring post nasal drip can sometimes signal an underlying problem that needs evaluation.
Consider seeing an ENT if you have:
Treatment depends on what is causing the drainage.
An ENT may examine the nose, throat, and sinuses and consider whether allergies, sinus inflammation, infection, reflux, structural problems, or another condition may be contributing.
Depending on the cause, treatment may involve medication, allergy management, treatment of a sinus condition, reflux management, or another approach based on the individual diagnosis.
If post nasal drip keeps coming back, interferes with sleep, or causes ongoing coughing or throat irritation, Glatz Group can help determine what may be causing it.
