Never said why she was on methadone. FDA Black Warning for methadone:
Benzodiazepine drug interaction warning: Taking methadone together with drugs that affect the nervous system, or drugs called benzodiazepines, may cause severe drowsiness, breathing problems, coma, or death. Benzodiazepine drugs such as Valium and methadone don’t mix with alcohol. Very sad.
Isn’t methadone a drug to wean people off of heroin?
And how many times are people warned about grapefruit's interaction with certain drugs? Or have seen a sticker on a prescription container like the one pictured here...?
