Post Nasal Drip


Post nasal drip refers to the sensation of having excess secretions (either thick or thin) from the nose and sinus which drips down the back of your throat.


Post nasal drip occurs when the mucous membrane and nose glands produce excess mucus due to irritation. There are several substances that can irritate the mucous membrane including:

  • Allergies
  • Inhalants e.g. dust mites, animal dander, pollen, and mold
  • Deviated nasal septum
  • Cold air
  • Spicy foods
  • Drugs
  • Cigarette smoke
  • Alcohol
  • Cold temperatures
  • Sinus or nasal infections
  • Pregnancy and changes in hormones
  • Low humidity
  • Side effects of other medication
  • Nasal tumors
  • Gastroesophageal reflux


  • Need to continuously clear one’s throat
  • Bad breath
  • Clear nasal discharge
  • Continual sore throats
  • Sinus or nasal congestion
  • Yellow or white crystals on your tonsils and adenoids
  • Yellow coating on your tongue
  • Hoarseness or raspy voice


Treatment options for post nasal drip vary from person to person due to the varying cause. In attempting to relieve post nasal drip, one must first see his/her doctor for careful and detailed diagnosis. Various tests and x-ray aid in determining the cause of PND. It is dangerous to take medication for post nasal drip without the doctor's consent because some causes do not respond to certain medications and may worsen the condition.
The successful use of each of the following medication is dependant on what caused the infection. If used without a qualified health practitioner's consent or instruction, certain remedies may rather worsen the condition or cause other complications. There are certain medications that do not respond to PND:

  • Steroid nasal sprays
  • Nasal washes
  • Antihistamines
  • Antibiotics
  • Nasal irrigation
  • Decongestants

Often the key is to simply drink enough water to liquefy the secretions. Ice drinks slow the cilia, and so do most antihistamines. Sometimes patients may be put on a large number of various medications which combine to make the nose dry.
