Post Nasal Drip

By DuPage Medical Group Primary Care

Underlying causes of postnasal drip include allergies, colds and sinusitis. In addition, some people have chronic inflammation of the nasal passages and runny nose, which can also cause postnasal drip.

People with postnasal drip may complain of symptoms including stuffy or runny nose, sensation of liquid in the back of the throat, or frequent throat clearing. However, some people have so-called “silent” postnasal drip; they have postnasal drip but don’t realize it. The physician will sometimes suspect postnasal drip based on the appearance of the patient’s throat. The physician will always consider and sometimes treat, postnasal drip in a patient with chronic cough when no other apparent cause is present.

Treatment of Postnasal Drip

Patients with or without symptoms of postnasal drip may be treated for this condition to see if the cough improves. Therapy may include antihistamines and decongestants, nasal steroids, or ipratropium nasal spray. If sinusitis is suspected as the cause of the postnasal drip, antibiotics may be helpful.
