The prevalence ofSJS, TEN and HSS were most often found in patients treated withcarbamazepine, allopurinol and phenytoin, respectively. Mortality rateof SJS, TEN and HSS were 6.90%, 50.0% and 12.82% respectively.Conclusion : Top three main drug groups causing SCAR were, namely: anticonvulsants(34.56%), antimicrobial (25.74%) and antigout (14.70%).Allopurinol revealed the highest mortality rate.
