Permethrin is used to treat scabies.

Before you start

  • Tell your health professional if you are pregnant, planning to become pregnant, or breastfeeding.

How should you use it?

Everyone in the same household should be treated on the same day, even if they do not have a rash or itch.

Apply before bed when the skin is cool and dry. Apply over the whole body, including the ears, scalp, hair, neck, and face, and especially between your toes and fingers, and under the nails. You can use a soft brush to get under your nails. Keep it out of your eyes, nose, and mouth.

Leave it on overnight (at least 8 hours) as directed, then wash off in the morning. If you wash your hands during this time, make sure to reapply.

Repeat the whole treatment after 7 days to make sure the infection does not come back.

You can go back to work or school 24 hours after the first treatment.

What if you forget a dose?

If you forget to reapply after 7 days, reapply it as soon as you remember.

Can you take other medicines?
