**Abstract**

Health literacy related to prescribed medications instructions is the ability to read, understand and carry out medication instructions as directed. Being generally literate does not automatically make one to be health literate. In most cases, a person's health literacy is overlooked based on their good general literacy. A convergent parallel mixed method design was used to explore and describe the practices of diabetes mellitus patients regarding prescribed medications instructions. The results showed failure to interpret medications instructions which leads to non-adherence unaware. On the other hand, non-adherence led to complications. Enhancing health literacy includes explanation of the medication instructions in details including the exact times for medication consumption. This could be achieved through peer teaching, health talks with patients and workshops.
