You tell whomever it is that is ordering your drug test (not the lab) that you are taking prescription medication that will cause a positive result on your drug screen (assuming that the medication that you are on is actually one of the drugs tested for), and give him/her a copy of your prescription. Your doctor doesn't need to explain anything-that's what the prescription is for.
