Do you know what the time frame is on a valid prescription? Say I have a Rx for cough syrup from 11/11/17 – do I still have a valid prescription?
MRO's use their discretion on this. Company policy might apply. Our team at National Drug Screening, says
Unless an employer chooses not to accept Rx's past a certain time, for example 1 year, we will accept old Rxs as long as we can validate them. So we would accept the Rx from 11/11/17.
