This article will explore ways to identify the causes of post-nasal drip and the most effective home treatments. You'll also find information on when to seek professional help and how to find relief from this frustrating condition.


Post-nasal drip, also known as rhinorrhea, is a condition where mucus accumulates in the back of the nose and throat, often causing discomfort and irritation. It can be caused by various factors, such as allergies, sinus infections, acid reflux, or even changes in weather. It is important to treat post-nasal drip promptly to avoid complications like infection, sore throat, or cough. This article will provide an overview of the most effective ways to treat post-nasal drip at home.

Identifying the causes of post-nasal drip and appropriate treatments

The first step in treating post-nasal drip is identifying the underlying cause. Here are some common causes and their corresponding treatments:


Allergies are one of the most common causes of post-nasal drip. Antihistamines, such as loratadine or cetirizine, can be used to block histamine, which causes allergy symptoms like a runny nose or sneezing. Nasal corticosteroids, like fluticasone or mometasone, can also help reduce inflammation and mucus production in the nose. For more severe allergies, a course of immunotherapy (allergy shots) may be recommended.

Sinus infection

Sinus infections can cause post-nasal drip, as well as other symptoms like facial pain, nasal congestion, or headache. Decongestants, like pseudoephedrine or phenylephrine, can be used to shrink swollen nasal passages and relieve congestion. If there is evidence of a bacterial infection, your doctor may prescribe antibiotics. Irrigation or flushing of the nasal passages with a saline solution can also help to flush out excess mucus and provide relief.

Acid reflux

Acid reflux, or gastroesophageal reflux disease (GERD), can result in a chronic post-nasal drip. In this case, proton pump inhibitors (PPIs), like omeprazole or pantoprazole, can help reduce the amount of acid in the stomach, which can alleviate symptoms. Antacids can also be used to neutralize acid that has already been produced.

Other causes

There are other potential causes of post-nasal drip, ranging from hormonal changes, pregnancy, alcohol and caffeine consumption, to medications or environmental irritants like smoke or pollution. Treatment depends on the root cause, and can often involve avoiding triggers, making lifestyle changes, or taking medication as prescribed by a healthcare professional.

Over-the-counter medications for post-nasal drip

Several over-the-counter (OTC) medications can help alleviate symptoms of post-nasal drip:


OTC antihistamines can be used to alleviate allergy-related post-nasal drip. They work by blocking the release of histamine, which can trigger symptoms like runny nose or sneezing. Some common brands include Claritin, Zyrtec, and Allegra. Note that some antihistamines can cause drowsiness and may interact with other medications, so it’s important to read the label carefully and consult with your doctor or pharmacist if you have any concerns.


OTC decongestants work by shrinking swollen nasal passages and reducing congestion, which can alleviate post-nasal drip. Examples include Sudafed, Afrin, or Dristan. However, decongestants can also cause side effects like elevated blood pressure, nervousness, or insomnia, so they should be used with caution and only as directed.

Saline nasal sprays

Saline nasal sprays can be used to soothe irritated nasal passages and loosen mucus. They work by moisturizing the nasal passages, which can reduce irritation. They can be used as frequently as needed and typically have fewer side effects than OTC medications.

Natural remedies for post-nasal drip

In addition to medication, there are some natural remedies that can help alleviate post-nasal drip:

Drinking plenty of fluids

Staying hydrated is important for thinning mucus and reducing inflammation, which can alleviate post-nasal drip. Drinking warm liquids like tea or broth, or simply increasing water intake, can help soothe a dry throat and reduce congestion.

Using a humidifier

Using a humidifier can help add moisture to the air, which can help prevent nasal passages from drying out and becoming irritated. A cool-mist humidifier is recommended, especially at night, to help improve sleep quality and relieve congestion.

Avoiding triggers like smoke or allergens

Avoiding triggers like smoke or allergens can help reduce the frequency and severity of post-nasal drip. This may include avoiding smoking, or using air filters to reduce pollen or mold in the air. Maintaining good indoor air quality and reducing exposure to irritants can help prevent symptoms from worsening.

Other natural remedies

Other natural remedies for post-nasal drip include inhaling steam, using a neti pot, or drinking warm lemon water with honey. Some people also find relief from inhaling the scent of eucalyptus or peppermint oil, or using acupuncture or acupressure to stimulate the sinuses.

Oral hygiene habits and lifestyle changes for post-nasal drip

Improving oral hygiene and making lifestyle changes can also help prevent or alleviate post-nasal drip:

Brushing and flossing regularly

Good oral hygiene habits, like brushing and flossing regularly, can help reduce bacteria in the mouth and throat. This can help prevent infections, reduce inflammation, and prevent post-nasal drip from worsening.

Reducing caffeine and alcohol intake

Caffeine and alcohol can cause dehydration, which can exacerbate post-nasal drip symptoms. Reducing consumption of these beverages, or avoiding them altogether, can help alleviate symptoms.

Quitting smoking

Smoking can cause chronic inflammation and irritation of the nasal passages and throat, as well as exacerbate allergies and other respiratory conditions. Quitting smoking can help reduce inflammation and improve overall respiratory health.

Avoiding spicy foods

Spicy foods can cause irritation and inflammation of the mouth and throat, exacerbating post-nasal drip. Reducing or avoiding spicy foods, especially during periods of congestion or infection, can help soothe symptoms.

Post-nasal drip remedies for children and infants

Children and infants may also experience post-nasal drip, which can be treated with these non-medicinal remedies:

Using saline drops or spray

Saline drops or spray can help loosen mucus and soothe dry nasal passages. They can be used before feeding or sleeping to help relieve congestion.

Using a humidifier in their room

A cool-mist humidifier can help add moisture to the air, which can soothe irritated nasal passages and promote better sleep.

Reducing exposure to allergens and irritants

Reducing exposure to allergens, smoke, or other irritants can help prevent post-nasal drip in children and infants. This may include making changes to the home environment, avoiding certain foods or substances, or using air filters.

When to see a doctor

While most cases of post-nasal drip can be treated at home, it’s important to seek medical advice if symptoms persist or worsen. You should also seek medical attention if post-nasal drip is accompanied by other symptoms like fever, coughing, or difficulty breathing. Medical professionals can provide additional treatment options like prescription medication or allergy testing.


Post-nasal drip can be a frustrating and uncomfortable condition, but there are many effective ways to alleviate symptoms. By identifying the underlying cause and using appropriate medication, natural remedies, and lifestyle changes, you can find relief from post-nasal drip and prevent complications. Remember to always consult with a healthcare professional if symptoms persist or worsen, and seek prompt treatment to avoid complications.
