Let us know if you are allowed to return an Rx - even in the unopened container in the unopened mailing package.
Back when I was dealing with pharmacy counters they had conniptions over my refusing to accept a container of stuff I told them I did not want, doctor phoning in the order be damned. Using the fill-by-mail service I once got a bottle of stuff that had not been ordered for me - Doc confirmed that no order/Rx had been submitted, Medco even admitted they had no record of receiving an order/Rx. They agreed to issue a check to me refunding the charge against my credit card and asked me nicely to please properly dispose of 300 pills by dumping them into the wastewater stream where the processing would not remove the contents before it was released to become someone else's drinking water. But taking back the unopened bottle that still had their security foil intacct? Nooooooooooo!!!!!!!!!! They could not, would not, not in any past or future lifetime let alone the current one.
I've often wondered how the landfill changed (at least that one little spot) after receiving a massive dose of Vitamin B-3.
stay safe.
