Should I be concerned if my 96-year-old mother is sedated from her medication?

Well, the risperadol is for schizophrenia, and the shot lasts two weeks. She doesn't need the daily pill. The zoloft is for depression, and the klonopin is for anxiety. From past experience, I think you should ask the doctor to ween her off of the klonopin, or at least lower the dosage. That is the one that is making her drowsy, lethargic.
