A system to reduce error in procurement of over-the-counter medications that has a prescription drug dispensing container that contains a prescription medication, an over-the-counter drug dispensing container that contains an over-the-counter medication, indicia displayed on the over-the-counter drug dispensing container, and a procurement guide that links the procurement of the over-the-counter medication to the procurement of said prescription medication and allows identification of said over-the-counter medication by matching indicia on the procurement guide to the indicia on the over-the-counter drug dispensing container.
