Special precautions to be taken by the person administering the veterinary medicinal product to animals
Do not eat, drink or smoke while using the product.
Wash hands and exposed skin before meals and after work.
Avoid contact with skin, eyes and mucous membranes, and oral uptake. Wear impervious gloves. Change heavily
contaminated clothes and wash before re-use.
In case of skin contact, wash the exposed parts thoroughly with water and soap.
In case of eye or mucous membrane contact, immediately rinse thoroughly with water.
People with known hypersensitivity to the product or one of its components should avoid contact with the product. If
you feel unwell after the use of the product, seek medical advice immediately and show the package leaflet or the label
to the physician.
Environmental precautions
Deltamethrin must not enter surface water as it is toxic to fish and other aquatic organisms.

4.6 Adverse reactions (frequency and seriousness)
Hypersensitivity reactions can occur. In very rare cases following treatment, skin irritation with restlessness, heads
tossing and tail flicking has been observed.
The frequency of adverse reactions is defined using the following convention:
 very common (more than 1 in 10 animals displaying adverse reaction(s) during the course of one treatment)
 common (more than 1 but less than 10 animals in 100 animals)
 uncommon (more than 1 but less than 10 animals in 1,000 animals )
 rare (more than 1 but less than 10 animals in 10,000 animals)

4.7 Use during pregnancy, lactation or lay
No restrictions apply for use during pregnancy and lactation.

4.8 Interaction with other medicinal products and other forms of interaction
Some organo-phosphorous insecticides can reduce metabolism rate and thus enhance Deltamethrin toxicity. Therefore, it is
not advisable to use in association with organo-phosphate insecticides.

4.9 Amounts to be administered and administration route
Route: For external topical use.
Apply the recommended dose by pouring it along the animals spine from the base of head to the tail. For sheep, it is
recommended that the fleece is parted during administration.
Lice: One single application is generally enough for 8-10 weeks protection, but in cases of heavy infestation it may be
necessary to repeat the treatment after 4-6 weeks. All in contact animals must be treated at the same time.
Flies: One single application provides protection against flies for 6-10 weeks depending on the degree of infestation, fly
species and weather conditions.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Overdose of twice the recommended treatment dose does not induce any adverse effects.

4.11 Withdrawal Period(s)

Pharmacotherapeutic group: Pyrethrins and pyrethroids.
ATCvet Code: QP53AC11.

5.1 Pharmacodynamic properties
Butox 7.5 mg/ml Pour-on is an ectoparasiticide whose active ingredient Deltamethrin belongs to the synthetic pyrethroids
class. Its mode of action concerns the neurotransmission involving sodium channels in the target parasite.

5.2 Pharmacokinetic properties
After dermal application, Deltamethrin is slightly absorbed through skin of cattle and sheep and remains available to
the target ectoparasite. The main route of excretion of the absorbed amount in the target animal is the faeces. In terms
of residues, fat is the target issue.
