Librium is "the" original benzodiazepam. Its an old drug I really have not heard of it used recently. Its in the family of commonly known drugs like xanax and valium. It is highly addictive.
It is used for alcohol withdrawal among other things. It works on the brain in the same way alcohol does. IMO (I am not a doctor) it should only be used for a short time in detox under medical supervision.
Not a fan of replacing one addiction with another.
With your mom's level of alcoholism I would *guess* a medical detox a necessity. She could get very sick trying to do it on her own, she could die.
I am not sure what you are asking - is she asking for the return of the medication? Are you questioning whether or not to give it back to her?
The only remedy I know of for alcoholism or addiction is choosing recovery. I don't know of any alternative therapies but for her, a medical detox I would say is protocol.
