CHRONIC TOXICITY: Permethrin caused neurobehavioral effects (e.g., tremors) and/or organ effects (liver, lung, kidney) in chronic studies in rats, mice and dogs. Permethrin exposure resulted in significant decreases in neurologically-active proteins, c-fos and BDNF, in young rats (7). Even at high concentrations, they are still safe for dogs, so it is very rare to see permethrin poisoning in dogs. Chronic oral exposure Permethrin is rapidly absorbed from the gastrointestinal tract and extensively metabolized following an oral dose, and effects are typically observed within 2 to 5 hours after dosing.
