Provides ionized calcium for neuromuscular function, cardiac conduction, and bone metabolism. Cardioprotective against hyperkalemia.
IV administration must be SLOW with ECG monitoring (cardiac arrest risk). Tissue necrosis if given SC undiluted at high concentrations. Dilute for SC use. Monitor ionized calcium levels.
Species-specific contraindications and adverse-reaction reports for cats may differ from canine / feline reference data — consult the primary citations listed with each rule.
Calcium Gluconate dose ranges in cats, with cited source references: IV 50–100 mg/kg q6-8h; IV 50–100 mg/kg once; PO 50–75 mg/kg q8h; SC 50–100 mg/kg q6-8h. Reference ranges from cited sources — verify against current literature before clinical use.

Calcium Gluconate is indicated in cats for: Post-thyroidectomy hypocalcemia, Hypocalcemia, hyperkalemia (urethral obstruction), Post-parturient hypocalcemia prevention, Mild hypocalcemia.
These are general warnings for Calcium Gluconate across species; consult the cat dosing table above for species-specific guidance. IV administration must be SLOW with ECG monitoring (cardiac arrest risk). Tissue necrosis if given SC undiluted at high concentrations. Dilute for SC use. Monitor ionized calcium levels.
Why a species-specific page? Calcium Gluconate pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cats — the rules above are the citations specific to this species, not generic recommendations.
