Use of intravenous lipid therapy in three cases of feline permethrin toxicosis

OBJECTIVE: To describe the use of intravenous lipid emulsion (IVLE) as an adjunctive therapy in 3 cats with permethrin toxicosis. CASE SERIES SUMMARY: Three cats with permethrin toxicosis were treated with IVLE in addition to the current accepted treatment regime. All 3 cats demonstrated a subjective rapid clinical improvement after the administration of IVLE, with no adverse reactions observed. NEW OR UNIQUE INFORMATION PROVIDED: This is the first reported use of IVLE for feline permethrin toxicosis, with encouraging results. A possible reduction in costs associated with treatment may contribute to a reduction in euthanasia. Further investigation of the use of IVLEs in permethrin toxicosis is warranted.
