Active Constituent(s)
10 mg/mL butorphanol as butorphanol tartrate
(with 0.1 mg/mL benzethonium chloride preservative)
Indications
Analgesic and sedative for use in horses, dogs and cats. In cats, sedation does not occur with Butordyne Injection alone, but can occur in dogs with Butordyne Injection alone. Butordyne Injection may be used in combination with medetomidine hydrochloride and ketamine hydrochloride as a triple anaesthetic in dogs and cats.
Dosage
NOT TO BE USED in horses intended for human consumption. Discard unused portion 8 weeks after first broaching.
Horses:
For analgesia: The recommended dosage is 0.1 mg of butorphanol per kilogram of body weight (equivalent to 1 mL of Butordyne® Injection for each 100 kg of body weight) administered by intravenous injection. Butorphanol use should not exceed 48 hours in any one treatment episode.
Dogs:
When administering intravenously, inject slowly: do not inject as a bolus.
Due to the low volumes involved, great care should be taken when administering to animals weighing under 5 kg.
For analgesia: Administer by intravenous intramuscular or subcutaneous injection routes. Dose rate: 0.2 – 0.3 mL per 10 kg (equivalent to 0.2 – 0.3 mg butorphanol per kg) body weight. Analgesic effects are seen within 15 minutes. For continuous analgesia the dose may be repeated as required.
For sedation in combination with medetomidine hydrochloride: Butordyne Injection should be administered at 0.1 mL per 10 kg (equivalent to 0.1 mg butorphanol per kg) together with 10 – 25 μg medetomidine hydrochloride per kg body weight depending on the degree of sedation required, both by either intramuscular or intravenous injection. Allow 20 minutes for profound sedation to develop before commencing the procedure.
For use as a pre-anaesthetic: Dose should be reduced to 0.1 – 0.2 mL per 10 kg (0.1 – 0.2 mg butorphanol per kg), given 15 minutes prior to induction.
Cats:
Due to the low volumes involved, great care should be taken when administering Butordyne Injection to animals weighing under 5 kg. NOT recommended for intravenous use in cats under 5 kg body weight.
For pre and post-operative analgesia: 0.2 mL Butordyne Injection per 5 kg body weight (equivalent to 0.4 mg butorphanol per kg) should be administered either by subcutaneous or intramuscular injection.
For sedation in combination with medetomidine hydrochloride: Butordyne Injection should be administered at 0.2 mL per 5 kg body weight (equivalent to 0.4 mg butorphanol per kg) together with 50 μg medetomidine* hydrochloride per kg body weight, both by either intramuscular or subcutaneous injection.
*dose of medetomidine up to 50 ug/kg. Some situations may warrant reduced doses.
Withholding Period(s)
Meat (Horses): Horses producing meat or offal for human consumption must not be sold for slaughter during treatment or within 63 days of the last treatment.
