How dangerous can 6 CNS drugs be? I was on 5 CNS drugs, I recently placed on gabapentin, making 6 CNS drugs. I had been on the 5 for several years and doing great. How dangerous can adding gabapentin be? I have hypotension, cervical and lumbarsacral spondylisis, lumbar nerve root disorder, sacroiliac inflammation. I have bipolar 1 disorder, borderline personality disorder, OCD, and severe anxiety. I am having increased pain, problems with memory, confusion, concentration, drowsiness, and sleeping almost all the time. Should I ask the prescribing Dr if he read my chart? Especially preexisting conditions and medication list.
