I see the black box warning has to do with dementia patients. My bad. Thought the black box warning had to do with how Geodon changes the heart's QT interval although these changes can also be life threatening. Either way, I'm not inclined to change my med because it keeps my symptoms at bay. What's happening that you feel you might be allergic? If you have hives/rash, itching or swelling call your doctor right away.
