Hello, Welcome to HCM, Scabies is caused by small parasitic mites burrowing under the skin. The bumpy rash you can see on your child s skin is an allergic reaction to the eggs of the mites. Permethrin cream is the most common cream that is used in treatment of scabies. You need to spread over every inch of your body, from neck down. Even parts of his body that don t seem to be infected must be treated, so don t skip them. Don t forget to put the cream between your toes and fingers, under arms, in navel, and the genitals. Leave the cream on his skin for 12 hours and then wash it off. Other drugs like benzyl benzoate, crotamiton, lindane and malathion can be used but Permethrin cream is thought to be the safest of these remedies for your child. Thank you
