Post-nasal drip is a common affliction associated with colds, allergies, and other conditions. Our bodies are constantly producing mucus, which is beneficial because it traps germs and other debris that might cause us harm. We also continually have mucus draining down the back of our throats, but most of the time we aren't aware of it. When we do become aware of it, this is called post-nasal drip.

Post-nasal drip usually becomes an issue because something has caused the mucus in our bodies to become either excessively thick (viscous) or thin (watery). Post-nasal drip treatment is dependent on the root cause of the condition. This article will cover different types of treatments for post-nasal drip including things that you can do at home.

Treating Post-Nasal Drip at Home

There are some treatments for post-nasal drip that can be tried regardless of the exact cause. Things you should do at home for post-nasal drip vary slightly depending on whether the secretions are thick or thin. For more information about home remedies, read:

Treating Post-Nasal Drip Caused by Allergies

In addition to the suggestions above, the following are treatments for post-nasal drip caused by allergies:

  • Try an antihistamine, such as diphenhydramine or loratadine.

  • If you know what is causing your allergies, avoid triggers.

  • If you do not know what you are allergic to, you should see an allergist/immunologist to determine the cause and discuss the possibility of allergy shots.

  • If you suffer from pollen allergies, keep your windows closed during pollen season, and take a shower after coming indoors to remove any pollen that may have landed on your clothes or in your hair.

  • Decongestants, such as pseudoephedrine, can be used, but don't use them for more than three days in a row to avoid rebound congestion.

  • Newer nasal sprays, such as Nasonex, which claim to not cause rebound congestion, are available by prescription and can be used on a longer-term basis than traditional decongestants.

Treating Post-Nasal Drip Caused by Infections

Post-nasal drip can also be caused by infections, including the common cold, RSV, influenza, or sinusitis. The following treatments are available for post-nasal drip caused by an infection. It's important to also see a doctor to rule out the need for antibiotics.

  • Decongestants, including pseudoephedrine, phenylephrine, and Afrin (oxymetazoline), may be helpful. As noted above, avoid using these products for longer than three days to prevent rebound congestion. Decongestants are helpful for most adults but should not be used in children.

  • Drink as much water or other fluids as possible.

  • Vapor rubs or other products containing menthol, including cough drops, can be helpful, but only use them as prescribed. These products are not for use with small children.

  • Humidifiers and nasal saline mists can thin mucus.

Treating Post-Nasal Drip Caused by Acid Reflux (GERD)

Gastroesophageal reflux disease (GERD), or acid reflux, can cause post-nasal drip. GERD is a condition where acid from the stomach is regurgitated back into the esophagus. GERD is worse at night because gravity makes it easier for acid to "backwash" into the esophagus and back of the throat. Stomach acid is extremely irritating to tissue outside of the stomach, and this irritation of the back of the throat and esophagus can cause not only post-nasal drip, but also sore throat, laryngitis, and a persistent cough. To treat post-nasal drip caused by GERD:

  • Try an over-the-counter antacid, such as Tums, Zantac, or Prilosec.
  • Don't eat before bedtime.
  • Avoid trigger foods, such as chocolate, soda pop, or spicy foods.
  • Sleep in an elevated position instead of lying flat.
  • If acid reflux persists, see a doctor.

Treating Post-Nasal Drip Caused by Medications

The only cure for post-nasal drip that results as a side effect of a medication, such as birth control or blood pressure medications, is to stop taking the medicine. (Note: Do NOT stop taking a medication without your doctor's permission.) However, you should be aware that many side effects subside the longer a medication is taken.

To avoid a dangerous medication interaction, do not take any additional medications, even over-the-counter or herbal medications, for post-nasal drip without clearing them with your doctor and/or pharmacist. Humidifiers, saline mist, and neti pots can be used. Avoid dairy if mucus is thick, and avoid spicy foods if mucus is thin. Always drink plenty of water.
