Drug interaction is an interaction among a drug with other ingredients that prevents the drug from giving certain or expected effect. Such interaction might happen between a drug and other drugs, drugs with food, as well as drugs and disease. Potential drug interaction in patients with type 2 diabetes mellitus in some hospitals had been reported by several previous publications. This study aimed to identify the potential of drug interactions in patients with type 2 diabetes mellitus at Hospital X, South Tangerang.

The severity of interaction in moderate category was 89.39% (total of 66), and the rest was in minor category. Major categories were not found. The potential for drug interactions in type 2 diabetes mellitus patients is quite common and these findings complement the findings of previous published studies.
