Hi Lisa,
You should call the MD office and request an explanation. You will probably have to leave a message but I would ask for the nurse to call you regarding your medications and when she does, I would request her or the MD to explain why this was done. If they are unwilling to discuss this, request an appointment ASAP.
My other thought is...maybe the nurse called in the wrong medication. This happens and could be corrected very easily.
I hope you get some relief soon!
