I get pretty bad allergies around this time of year, and am usually pretty miserable unless I take something. I tried some Chinese herbal pills called Be Min Kan Wan, but that didn't work very well so now I'm going with the standard CVS allergy tablets. What I'd like to know is, from a TCM perspective are there any long-term harmful effects from over-the-counter allergy medications? As far as I know the only health risks are to people with high blood pressure, since the ephinedrine can exaggerate it. Since my blood pressure is normal and the dosage is only once a day (it's the 24-hour, non-drowsy kind) I don't see a problem with it.

Opinions?
