Individuals can treat mucus in the throat with antihistamines, decongestants, nasal sprays and steroid medications, recommends WebMD. Mucus or postnasal drip caused by bacterial infections is often treated with antibiotics to eliminate the infection from the body. Patients can also take mucus-thinning medication, use a nasal irrigation system to flush out allergens, mucus and bacteria and turn on a vaporizer while sleeping to increase moisture in the air to treat mucus in the throat.
Mucus in the throat caused by allergens can be treated by covering pillowcases and mattresses with dust mite-proof covers, washing sheets and mattress covers in hot water and using HEPA air filters in the home to reduce allergic agents, explains WebMD. Patients should also dust and vacuum regularly to remove allergens.
Individuals with mucus in the throat that is accompanied by wheezing, a fever and a foul smell should consult with a medical professional to determine the cause of the symptoms, according to WebMD. Symptoms that last more than 10 days may indicate a bacterial infection that requires prescription medication or the need for further evaluation with X-rays or a CT scan. Treatment for mucus in the throat is often targeted at the cause of the symptoms.
