the simple (albeit gross) answer is “spit it out” in a tissue if you can. most of the time phlegm will drain down the backs of our throats where it is harmlessly destroyed by powerful stomach acid. phlegm caused by allergies or colds tends to be thin so drying it up using otc antihistamines can be helpful. if phlegm is thick and sticky otc mucous-thinning agents and decongestants are available keeping in mind that this may actually increase the amount of phlegm you may need to expectorate or swallow. decongestants can also be stimulating and interfere with sleep. home remedies like saline nasal sprays gargling humidifying the air and drinking lots of water are effective. persistent darker-colored phlegm may be sign of a sinus infection.
