Setting realistic treatment goals for post-nasal drip: Complete cure (all symptoms gone, no medication needed): more likely in the short-term post-cold type and the dryness or environmental-cause type. Manageable level (reduced dose and frequency of medication, buffering seasonal flare-ups): the realistic goal for the chronic type with underlying allergic rhinitis. Maintaining quality of life (flare-ups one or two times a year, manageable with short-term care): for the long-standing type with overlapping combined causes (allergy, reflux, environment). The goal of Korean medicine treatment is to raise the threshold through constitutional improvement. The core is building a body in which the same irritation triggers fewer symptoms, and many people lower their use to taking antihistamines only when needed, on a short-term basis, even if they cannot stop completely.
