Treatment

 Medical department

The purpose of treatment is to kill insects, relieve itching, and treat complications.

Once diagnosed, scabies patients should be isolated immediately, and their clothes and bedding should be boiled and disinfected. Family members or people who live in a group should be treated at the same time.

The main treatment is external medicine. For severe pruritus, sedative and antipruritic drugs can be taken orally before going to bed. In case of secondary infection, antibiotics should be used at the same time.

Topical drug therapy

When applying the medicine, apply it all over the body from the neck (including the head and face of babies) to the feet, and don't miss the skin folds, around the anus, the edge of the nails and the skin folds at the root of the nails. The area where the rash is concentrated should be repeatedly coated with pressure and rubbed. Do not take a bath or change clothes during the medication period, and take a bath with hot water and soap after the course of treatment is over.
