A year ago, my wife had her bad hip replaced.
I bought her ten go home meds, they ran from Tylenol to various forms of oral codeine/narcotics with the exception of a $35 charge for for a box of injectable NarCan.
4 weeks later we returned most of the scheduled drugs and the unopened box of NarCan. Of course they were destroyed by the pharmacy.
I discussed the not used and not wanted NarCan. The pharmacist said that was due to the lawyers in case someone stole and used the Narcan and died.
How can you return them? I picked up a prescription for a relative once, ad it was the wrong one, but the pharmacy said they couldn't accept a return. Maybe states have different laws.
