They may not be authorized to refill since your husband just picked one up....maybe he would need to take the newest one up to the pharmacy and see if he can swap it for a new one that hasn’t been “frozen”. For the pharmacist to say it won’t hurt to take it but it may not do what it’s aupposed to do is silly.,.you only are taking it for what it’s supposed to do! Good luck. If no refill, I vote for the expired one.
