It may also be used for the treatment of head lice.
It should be used as per dose and duration suggested by your doctor.
If the condition persists after 14 days of treatment then the doctor may suggest another treatment.
Apply a thin layer of this medicine all over the body and leave it for 8-14 hours before taking a bath or shower.
