Myself personally have had bad reactions to medication combinations, in which I have a pdoc who prescribes these medications, I then approach the treatment team about my side effects in which the pdoc is able to know for the most part my symptoms, and which med or med combination is causing the side effect.

If concerned about toxic, I would and have gone to the emergency room at the Hospital to have blood medication levels and be medically cleared if needeed.

Good luck.
