ADVERSE REACTIONS (BSAVA Part B p.59, verbatim): Anaphylactic reactions may occasionally occur. SAFETY AND HANDLING (BSAVA Part B p.59, verbatim): Pregnant women should not administer the product. ACTION (BSAVA Part B p.59, verbatim): Synthetic GnRH (gonadotrophin releasing hormone) analogue that stimulates LH and FSH production, thus causing oestrus to develop and progress. USE (BSAVA Part B p.59, verbatim): To supplement natural LH in cases of ovulation failure or delay. Will also induce lactation postpartum in mammals. In males, it may stimulate testosterone secretion and is indicated in the management of genital hypoplasia and reduced libido. In ferrets it may be used in the management of signs of oestrus. In rabbits it is used to induce ovulation postpartum for insemination and to improve conception rates. In guinea pigs it can be used to resolve ovarian cysts if hormone-responsive. Used in birds for chronic egg laying (must be combined with husbandry changes). Used in trout to facilitate stripping in both male and female fish in spawning condition, and reduce mortality due to egg binding. SOURCE: Ramsey I, ed. BSAVA Small Animal Formulary, 10th ed.

Why a species-specific page? Buserelin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in kois — the rules above are the citations specific to this species, not generic recommendations.
