Introduction
Permethrin is the active ingredient of many 'spot-on' pesticides used in the control of fleas and ticks in dogs [1]. In is also used in products intended for use in rats, mice, gerbils and guinea pigs [1]. Permethrin mediates its effects through modulation of voltage-sensitive sodium channels. Cite error: Closing </ref> missing for <ref> tag.
Diagnosis
Clinical Signs
Includes: twitching, convulsions, ataxia, hypersalivation, respiratory distress, emesis, diarrhoea, hyperaesthesia, muscle fasciculations, lethargy, tachycardia, anxiety, temporary blindness,death [1], [1].
Laboratory Tests
Pathology
The spot-on canine preparations are often quite concentrated.[1]. Cats lack the enzyme glucuronidase transferase [1] and is therefore unable to utilise the metabolic pathway that dogs and other animals use to break down permethrin into glucuronides and sulphates [1]
Treatment
If permetrin toxicily is due to skin contamination immediate removal by washing with lukewarm water containing a gentle detergent such as shampoo or washing-up liquid is indicated [1].
