As per American psychological association drug interaction is defined as chemical or physiological reaction that can occur when two different drugs are taken together. Objective: This study was conducted for the detection of various drug interactions in dermatology in a tertiary care teaching hospital.

Results: A total of 108 patients were included in the study. Among them, 63 (58.3%) were males and 45(41.7%) were females. Of total 108 prescriptions, sever drug-drug interactions were present in 42 (38.9 %) prescriptions. Whereas, moderate drug-drug interactions were found in 14 (13%) and 52 prescriptions doesn’t have drug-drug interactions respectively. The study found the associations of potential drug interactions with age, sex, number of drugs per prescription. There was a direct link between polypharmacy and occurrence of drug interactions. To lower the frequency of potential interactions it could be necessary to make a careful selection of therapeutic alternatives, and in cases without other options, patients should be continuously monitored to identify adverse events. Conclusion: we concluded that educational interventions can minimize the incidence of drug interactions.
