Descriptive analysis of the ADR data collected is done by Microsoft Excel software and isexpressed as percentage comparison.
Results: A total number of 55 ADRs were reported during this seven months of period(August 2015 – February 2016) of which 27 were males and 28 were females. There is no significant difference between genders. The department of medicine reported the highest number of ADRs (27.2%) followed by general surgery (21.8%). The maximum number of patients (69%) was reported with dermatological manifestations. Majority of ADRs were due to antibiotics(63.6%). According to the Naranjo’s causality assessment scale, 85% of the ADRs were probable and 15% were possible. Severity assessment by Modified Hartwig and Siegel scale revealed 43.6% ADRs to be moderate, 36.3% were mild and 1.8% was severe.
Conclusions: The study accomplished that ADRs are widespread and a few of them raised the healthcare expenditure due to the increased hospital stay. The reporting of ADRs to regional pharmacovigilance centres should be encouraged to ensure drug safety.
