Results: At day 7, cure rate was similar in two groups (p=0.49) [Table 2]. Marginally, more patients in group A had very good response as compared togroup B. Final assessment was made at day 14. Results revealed 67.9% patients in group Aand 65.3% patients B had cure (p=0.87). Treatment failure was also similar in both groups(p=0.9) Conclusion: Both permethrin and ivermectin in both single and single dose regimenare equally efficacious and well tolerated in scabies. However, permethrin has a rapid onsetof action.
