It is not recommended to sleep with permethrin on your skin. Permethrin is a chemical insecticide that is used to treat and prevent infestations of lice, scabies, and other parasites.
While permethrin is generally considered safe for human use when used according to the instructions on the label, it is not intended to be used as a sleep aid. It is important to follow the instructions carefully and use permethrin only as directed.
After applying permethrin to your skin, it is recommended to leave it on for the recommended amount of time (usually 8-14 hours) and then wash it off thoroughly with soap and water. It is not recommended to leave permethrin on your skin for extended periods, as this could increase the risk of skin irritation or other adverse effects.
