I'm looking for information or site's that can provide me with the possible problems that could arise with combining old and new medications. I know a person that reorder's her medications every month and dumps the new pills in with the old ones in the old bottle. My concern is that the pills on the bottom never get used and if they did how old are they and what problems could arise. Without in hand printed info on this she thinks I'm crazy for worring or bringing it up.
Nothing. Old pills only get a little less effective, so you might not get quite as high of a dose as normal. Very few medications are dangerous when they get old, or expired, and these ones come with clear warnings on the bottle.
