Hi cta50, welcome to JA. Unless it is specified on the bottle, or your pharmacist disagrees, based on packaging, when (produced/ordered by pharmacy/bottled etc, I would not use past 28-30 days. I would call your pharmacist to verify his end of the ordering process. (He should also have an expiration date on his bulk size bottle that he prescribed from.)
