Permethrin, like all synthetic pyrethroids, is a neurotoxin. Symptoms include tremors, incoordination, elevated body temperature, increased aggressive behavior, and disruption of learning. Laboratory tests suggest that permethrin is more acutely toxic to children than to adults.

Please think twice before you put these poisons on your body and especially on your children. Check the ingredients on any over the counter ringworm or scabies remedy and ask your doctor if what they are about to prescribe for your child's ringworm, lice or scabies contains permethrin. If so, please take time to read about safe, effective alternatives to treating skin parasites.
