What Are Some Treatments for Excessive Mucus in the Throat?

Treatments for excessive mucus in the throat, also known as post-nasal drip, include taking antihistamines and decongestants when the mucus is caused by viral infections or sinusitis and taking antibiotics for bacterial infections that cause the body to produce excess mucus, explains WebMD. People with excessive mucus can also use a humidifier or vaporizer to reduce dryness in the air, prop up pillows at night while sleeping or take mucus-thinning medications.

Saline nasal sprays and nasal irrigation systems can also help to remove irritating substances from the sinuses, according to WebMD. Excess mucus in the throat is commonly caused by the flu, allergies, sinus infections, colds and changes in temperatures that produce dryness in the air. Some patients develop excess mucus when eating spicy foods, while taking medications such as blood pressure medications or birth control pills, and when exposed to cleaning products, smoke, perfumes and chemicals. Pregnancy and anatomical problems that affect the sinuses can produce excess mucus as well.

Preventative measures to reduce the risk of developing excessive mucus due to allergies include using HEPA air filters in the home, dusting and vacuuming regularly, covering bedding with dust mite-proof covers, and washing pillowcases, mattress covers and sheets in hot water, recommends WebMD.
