- Blood pressure, birth control, nasal sprays and some other medications
- Bright lights, cold temperatures
- During winter, heated homes and buildings become dry. This dryness thickens the mucus.
- Foreign particles blocking the nose, especially in children
- Head injuries
- Hormonal changes and pregnancy
- Sinusitis and / or chronic rhinitis trigger post nasal drip. It may also occur because of allergies, asthma, colds, flu and gastro-oesophageal reflux disease.
- Some spices and food items
- Sometimes structural problems, such as abnormal nasal septum, cause the drip.
- It may cause chronic cough or sore throat. The cough worsens at night.
- Secretions may block the Eustachian tube connecting the ear and the nose, creating pain and infection in the ear.
- The drip may block the sinus passages.
- Runny and blocked nose
- Bad breath (halitosis) and hoarseness

If you know what caused the drip, treatment is easier. First, try to find out the reason / factors for the drip. Consult your physician before administering any medicine. A thorough ENT examination may also be required.
You may need antibiotics to treat bacterial infections that may produce yellow or green mucus.
The drip caused by viral infections and sinusitis may be treated with decongestants and antihistamines. Although antihistamines reduce the level of mucus, some of these medications may make you sleepy.
Nasal sprays and steroid medications may be used for allergy- associated post nasal drip.
Since thick secretion creates discomfort, the mucus thinning is essential. Thin mucus will reduce chances of sinus and ear blockage. Drink lot of water and fluids to thin the mucus. Alternatively, try mucus-thinning medicines. You may use nasal irrigation or saline nasal sprays to drain out the excessive discharge and other irritating particles. Moisturize room air by switching on humidifier or vaporizer. Try special HEPA air filters for your home.
