Potassium Chloride / Potassium Gluconate
Also known as: Tumil-K, Renakare, Potassiject, Cal-Dextro K, K-G Elixir, Kaon, Kaylixir, Potasoral, Sopa-K, Ultra-K
> **Important:** Never give human potassium supplements to your pet without explicit veterinary approval, as dosing is highly specific and overdoses can be fatal. * **Administration:** Mix oral powders, gels, or liquids thoroughly into your pet's food to prevent stomach upset and improve palatability. * **Refusal to Eat:** If your pet refuses to eat the medicated food, contact your veterinarian. Do not force-feed or double the next dose. * **Monitoring:** Watch for signs of muscle weakness, severe lethargy, vomiting, or diarrhea. Contact your vet immediately if these occur. * Keep all potassium supplements out of reach of children and other pets.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.
What it is used for
- Treatment of chronic mild hypokalemia (3.0-3.5 mEq/L)
- Treatment of chronic mild hypokalemia (Tumil-K powder)
- Moderate to severe (<3.0 mEq/L) or acute hypokalemia
- Subcutaneous fluid supplementation (<10 kg patients)
- Oral maintenance supplementation
- Sliding scale IV supplementation based on Serum K+
- Hypokalemia in 'downer' cows
- Hypokalemia maintenance/treatment
- Severe hypokalemia (<2.3 mEq/L) with severe muscle weakness or recumbency
- Counteract potassium depletion in a completely anorectic horse
- Hypokalemia with diarrhea
- Treatment of chronic mild hypokalemia (3.0-3.5 mEq/L)
How it is given
Possible side effects
- Hyperkalemia (muscle weakness, cardiac conduction disturbances)
- Gastrointestinal distress (vomiting, diarrhea) with oral therapy
- Vein irritation and phlebitis with IV therapy
Cautions & contraindications
- Hyperkalemia
- Renal failure or severe renal impairment
- Severe hemolytic reactions
- Untreated Addison's disease (hypoadrenocorticism)
- Acute dehydration
- GI motility impairment (for solid oral dosage forms)
- > **CRITICAL WARNING:** Intravenous potassium salts **MUST** be diluted before administering and given slowly. Rapid IV administration can cause fatal cardiac arrest. * **Maximum standard IV rate:** Generally should not exceed 0.5 mEq/kg/hour. In dire circumstances (<2.0 mEq/L), rates up to 1.5 mEq/kg/hour may be used **only** with continuous ECG monitoring. * Assess renal and cardiac function prior to therapy. * Acid-base balance masks the actual potassium picture: acidosis causes a false elevation (shifts K+ out of cells), while alkalosis causes a falsely low serum value. * Supplementation should generally occur over 3-5 days to allow equilibration between extracellular and intracellular fluids. * Use cautiously in digitalized patients.
Drug interactions
- ACE Inhibitors (e.g., enalapril): Potassium retention may occur; increased risk for hyperkalemia.
- Digoxin: In patients with severe or complete heart block receiving digitalis therapy, it is often recommended not to use potassium salts.
- NSAIDs: Oral potassium given with non-steroidal anti-inflammatory agents may increase the risk of gastrointestinal adverse effects.
- Potassium-Sparing Diuretics (e.g., spironolactone): Potassium retention may occur; increased risk for hyperkalemia.
