Background: The objective of the study was to assess the pattern of cutaneous adverse drug reactions reported by active surveillance to the Pharmacovigilance center of a tertiary care hospital in southern india, and also to establish the drugs causing the same and observe the age wise and gender based incidence of such reactions.

Methods: The cutaneous ADRs (CADRs) reported to the Pharmacovigilance center of the institution were analysed retrospectively during the period of March 2013 to December 2015. The various pattern of skin reactions and the most frequent drugs causing the same were established. An age wise and gender based incidence of CADRs and drugs causing them were also reported.

Results: A total of 293 cases were taken for analysis. The male female ratio was our study. Among the age wise distribution of CADRs, 57(19.4%) were seen in paediatric, 194(66.2%) in adults and 33(11.2%) in geriatric age groups. The most frequent drugs to cause the CADRs were antimicrobials 183(62.4%) followed by NSAIDs 38(12.9%) and antacids 17(5.8%).Among the skin reactions urticaria/ angioedema was the most common 109(37.2%) followed by generalised pruritis 57(19.5%) and fixed drug eruption 37(12.6%). In all the age groups and both the sexes urticaria/angioedema and generalised pruritis were the leading skin reactions observed.

Conclusions: As CADRs are the most common ADRs among others, it is prudent to monitor them closely, as any change in pattern with older or newer agents can alert the health care personnel in instituting the appropriate prescription patterns, which can overall impact the quality of health care positively.
