Meprozine and hallucinating

I had a laproscopic on my gall bladder, was prescribed Meprozine 50/25 capsules QUA 1 capules ever 4hours for pain and sent home, this was on Thursday; Friday I became delirous, hallucinating, had to urinate all the time, had small seizuers, not in control of my body movements (twitching), dizziness. After admitted into the hospital developed pneumonia, put on abuterol, oxygen, different IV pain medication, was given blood thinners, and readings were done regularly on my blood gases. I was released after 4days when I realized I had a white rash on my neck, went back to the Dr's. office and was give a shot for the rash and cordizone. I have discoloration on my neck from the rash.

I took Meprozine after minor surgery. I became disoriented and confused (sorted the mail and then threw it all away including 2 checks, among other wierd behavior) I was talking with my granddaughter and suddenly she disappeared (she never was there, I was hallucinating) My speech was slurred and rambling. It was a horrifying experience that still haunts me weeks later.
