Opinion anaphylaxis

Hello guys, writting to you from ER. Took my cromolyn this evening and after 15 minutes my throat started closing, couldn.t breath, had the impending doom and felt like syncope and foggy vision. They gave me IV hydrocortison, and it.s a little bit better now. I really feel cromolyn is helping me in some ways, but it.s giving e this kind of respiratory reactions which I.m not comfortable with to be honest. Is it worth it to keep going with cromolyn?
