WOW ...that could be Scary for sure. I wonder "if" they were the same pill just from a different supplier? I have had that happen before (never in the same bottle) where the pharmacy had used a different supplier and the pills were the same but different. If the pharmacy doesn't say anything when I pick up the order then when I get home I call them and ask. Also I have searched on the web and I find the pill and what it is to look like.
Pharmacy's DO make mistakes.
