For the future and for anyone reading this post, if you do not understand your doctor's instructions, you should call the office and let the staff know you need clarification.
They will ask the doctor and someone should call you back by the end of the business day. It is difficult to ask a question such as yours in a forum like this because we do not know all the details of your case and what your doctor was trying to accomplish with the medication regimen.
Hopefully everything is sorted out by now.
All the best.
