Z-itch is a ready-to-use, pour-on solution containing Permethrin 40mg/ml (cis:trans 80:20) which aids in the control of sweet itch in horses and donkeys, It should be administered at the rate of 4mg/kg body weight, equivalent to 1.0ml per 10kg body weight to a maximum of 40ml.
Apply the measured dose in approximately equal proportions to the mane and rump avoiding the saddle area. Treatment should be started at the beginning of the sweet itch season and repeated as necessary – treatment once weekly should be sufficient for most horses.
If horses and donkeys are to be groomed, apply the product after grooming. Do not treat the saddle area. The product must not be applied forward of the ears. Take care to avoid eye contact. In case of accidental splashing into the horse’s eye, the affected eye should be washed thoroughly and immediately with copious quantities of clean water and veterinary attention sought.
