Mechanism of action

Essential cofactor for pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and transketolase in energy metabolism. Critical for neurological function.

Side effects & warnings

Deficiency causes polioencephalomalacia in ruminants and neurological signs in cats (fish-based diets, cooked meat diets). IV thiamine can cause anaphylaxis — give IM or slow IV. Very safe orally.

Species-specific contraindications and adverse-reaction reports for sheep may differ from canine / feline reference data — consult the primary citations listed with each rule.

Thiamine dosing in other species

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