if you are seeing your allergist it would not be wise to take prednisone since it would interfere with allergy testing. however since i do not know the reason why you are taking prednisone in the first-place you need to consult the medical provider that prescribed it for you since it should be tapered off in reducing doses and not abruptly stopped. antihistamines will also interfere with allergy testing etc. albuterol is fine to take. as far as treating the symptoms of your cold and coughing i would also suggest that you defer treatment suggestion to your medical provider because i do not know your medical history.
i am to see an allergist on tuesday. i have to stay off all antihistamines. is predisone or albutera an antihistamine. i have the flu and i am coughing and very congested. how can i get relief without taking an antihistamine?
