Can physostigmine ointment be used to treat lice in eyebrows or eyelids?

Physostigmine ointment is not typically used for treating lice in the eyebrows or eyelids. While it is an acetylcholinesterase inhibitor primarily used in specific medical contexts, its safety and efficacy for lice treatment in sensitive areas like the eyes and eyebrows have not been established. Over-the-counter treatments specifically designed for lice, such as permethrin or pyrethrin, are recommended instead. Always consult a healthcare professional before using any medication on sensitive areas.
