Butox Swish, Pour-on Suspension 7.5 mg/ml

Cases of resistance to deltamethrin have been reported in stinging and nuisance flies in
cattle. The veterinary medicinal product will reduce the number of flies resting directly on
the animal, but it is not expected to eliminate all flies on a farm. Therefore, the use of this
veterinary medicinal product should be based on local (regional and farm)
epidemiological information about susceptibility of parasites and used in association with
other pest management methods.
Care should be taken to avoid the following practices because they increase the risk of
development of resistance and could ultimately result in ineffective therapy:
-
too frequent and repeated use of ectoparasiticides from the same class over an
extended period of time;
-
underdosing, which may be due to underestimation of bodyweight,
misadministration of the product, or lack of calibration of the dosing device.
If clinical signs do not resolve following treatment, the diagnosis should be revised.

Special precautions for safe use in the target species:
Do not apply on or near the animal’s eyes and mucous membranes.
Care should be taken to prevent the animal licking the veterinary medicinal product.
Avoid use of the veterinary medicinal product during extremely hot weather and ensure
animals have adequate access to water. The veterinary medicinal product should only be
administered onto undamaged skin as toxicity is possible due to absorption from major
skin lesions. However, signs of local irritation may occur after treatment as skin may
already be affected by infestation.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
People with known hypersensitivity to deltamethrin should avoid contact with the
veterinary medicinal product.
Personal protective equipment consisting of waterproof apron and boots and impervious
gloves should be worn when either applying or handling the veterinary medicinal product
or recently treated animals.
Remove heavily contaminated clothing immediately and wash before re-use. Wash
splashes from skin immediately with soap and plenty of water. Wash hands and exposed
skin after handling this veterinary medicinal product and before meals.
In case of contact with eyes, rinse immediately with plenty of clean, running water and
seek medical advice.
In case of accidental ingestion, wash out mouth immediately with plenty of water and
seek medical advice.
Do not eat, drink or smoke while handling the veterinary medicinal product.
To the user:
This veterinary medicinal product contains deltamethrin, which may produce tingling,
itching and blotchy redness on exposed skin. Irritation, sensitisation and adverse effects
on the neuronal system might occur. If you feel unwell after working with this veterinary
medicinal product, seek medical advice immediately and show the package leaflet or the
label to the physician.
To the physician:
Advice on clinical management is available from the National Poisons Information
Service.
Special precautions for the protection of the environment:
Deltamethrin is very toxic to dung fauna and aquatic organisms.
The risk to dung fauna can be reduced by avoiding too frequent and repeated use of
deltamethrin (and other synthetic pyrethroids) in cattle, e.g., by using only a single
treatment per season on the same pasture.
