Throat swab culture. A nasal wash helps remove phlegm from the nose and sinuses. This can temporarily reduce the postnasal drip and lessen the dark brown phlegm. A prescription nasal steroid spray decreases nasal swelling and phlegm production. This may prevent the postnasal drip and dark brown phlegm. To get the most out of a nasal steroid spray use it after doing a nasal wash. A nasal steroid spray does not provide immediate relief of symptoms. It may require several weeks of routine use to become effective. Please read our Nasal Wash MedFact at http://www.nationaljewish.org/medfacts/nasal.html for more information about this technique.
