In this condition factsheet:
Diagnosing Post-nasal Drip
The first step is to figure out what's causing the post-nasal drip. Your doctor will help with this by asking questions about your symptoms and examining your ears, nose, and throat. Your doctor will want to know if you have any allergy symptoms or if you have symptoms of an infection (e.g., fever). In some cases, other tests (e.g., X-rays) may be needed to determine the cause.
The type of mucus in your nose can reveal a lot about possible causes of nasal drip. If the mucus is clear, a common cold or allergies are most likely. If it is thick and has a yellow or green tinge, a bacterial infection may have developed.
Treating and Preventing Post-nasal Drip
The treatment of post-nasal drip depends on its cause.
If your doctor determines that an infection is causing post-nasal drip, the infection will most likely be caused by a virus and antibiotics are not required. However, decongestants may help a stuffy nose and pain relievers can be used to help with pain. Sometimes, bacterial infections can occur and antibiotics may be prescribed.
Pseudoephedrine* and phenylephrine are the most common decongestants in over-the-counter cold medications taken by mouth. Talk with your doctor or pharmacist before using decongestant medication if you have high blood pressure, diabetes, thyroid disease, glaucoma, or prostate enlargement. Nasal spray decongestants include those containing phenylephrine, oxymetazoline, or xylometazoline. They should not be used for more than 3 to 5 days, as they may cause congestion to worsen when used on a regular basis for longer periods of time. Humidifiers or vaporizers can also help relieve symptoms of post-nasal drip. Regardless of cause, some antihistamines may be used to treat post-nasal drip since they help dry up the mucus.
If allergies are responsible for post-nasal drip, over-the counter antihistamines (e.g., loratadine, desloratadine, cetirizine, fexofenadine) can be used to help with symptoms. Talk to your doctor or pharmacist before starting an antihistamine. Your doctor may also prescribe a corticosteroid nasal spray (e.g., budesonide, fluticasone, mometasone) to help. Avoiding the allergies that cause runny noses can prevent post-nasal drip from happening again. Many people are allergic only during certain seasons or times of the year, mostly to pollens, moulds, or weeds. Year-round causes of allergies include mites, animal dander, and moulds.
*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®). The common name is the medical name for the medication (e.g., acetaminophen). A medication may have many brand names, but only one common name. This article lists medications by their common names. For information on a given medication, check our Drug Information database. For more information on brand names, speak with your doctor or pharmacist.
