Every held source for this drug and species, as printed. Where they differ, both are shown — the choice is yours, not ours.
The sources disagree for this combination. The ranges below do not overlap on a comparable route. This is not an error in one of them — published veterinary references differ, and reconciling them for a particular patient is a clinical judgement.
| Dose (meq/kg) | Route | Source | As printed |
|---|---|---|---|
| 1 | — | Papich Saunders Handbook of Veterinary Drugs, 4th edp.758 | • CPR: 1 mEq/kg with additional doses of 0.5 mEq/kg at 10-minute intervals. |
| 0.5 | — | Papich Saunders Handbook of Veterinary Drugs, 4th edp.758 | • CPR: 1 mEq/kg with additional doses of 0.5 mEq/kg at 10-minute intervals. |

Provides bicarbonate ions to buffer hydrogen ions. Raises blood pH. Shifts potassium intracellularly. Alkalinizes urine.
Use cautiously — overshoot alkalosis, hypernatremia, hypokalemia, decreased ionized calcium. Paradoxical CNS acidosis. Not routine in CPR. Monitor blood gases and electrolytes.
Species-specific contraindications and adverse-reaction reports for cats may differ from canine / feline reference data — consult the primary citations listed with each rule.
Sodium Bicarbonate dose range in cats, with cited source references: IV 1–2 mEq/kg IV slowly. Reference ranges from cited sources — verify against current literature before clinical use.
Documented routes for Sodium Bicarbonate in cats: IV.
Cited course lengths for Sodium Bicarbonate in cats include: Until pH corrected. Duration depends on the indication — match it to the specific dose rule in the table above.
Sodium Bicarbonate is indicated in cats for: Severe metabolic acidosis.
These are general warnings for Sodium Bicarbonate across species; consult the cat dosing table above for species-specific guidance. Use cautiously — overshoot alkalosis, hypernatremia, hypokalemia, decreased ionized calcium. Paradoxical CNS acidosis. Not routine in CPR. Monitor blood gases and electrolytes.
Why a species-specific page? Sodium Bicarbonate 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.
