Does venlafaxine xr really expire? if the bottle of pills begins to smell like vinegar, is this a sign of expiry?

Ee below: If the bottle of pills smells like vinegar and they have expired, get a new prescription.

Yes..: All drugs really expire at some point. I would definitely consider them expired or past their prime if they smell like vinegar- that's not normal! In general you should practice not taking pills that have already expired- to avoid getting sick and because they may not be as effective.
