Veterinary Drug Handbook (VDH) is the reference veterinarians turn to when they want an independent source of information on the drugs that are used in veterinary medicine today.


Dogs & Cats: Dog Cat

For hypokalemia:
a) Intravenous replacement: If animal has normal renal function, IV KCl not to exceed 0.5 mEq/kg/hr. Use IV replacement very cautiously in animals with impaired renal function or in those receiving potassium-sparing diuretics.
Subcutaneous replacement: If IV use is unfeasible or rapid correction is unnecessary, may add KCl to SQ fluids; do not exceed 30 mEq of potassium per liter.
Oral replacement: Potassium gluconate PO at a rate of 2.2 mEq per 100 calories of required energy intake or potassium gluconate elixir (20 mEq/ml) for dogs at 5 ml q8-12h PO. (Bell and Osborne 1986)
b) Oral using Tumil-K® (Daniels): 1/4 teaspoonful (2 mEq) per 4.5 kg body weight PO in food twice daily. Adjust dose as necessary. (Package insert; Tumil-K®¯Daniels).


For hypokalemia in "downer" cows:
a) 80 g sodium chloride and 20 g potassium chloride in 10 liters of water PO via stomachtube. Provide a bucket containing similar solution for cow to drink and anothercontaining fresh water. (Caple 1986)
For hypokalemia:
a) 50 grams PO daily; 1 mEq/kg/hr IV drip. (Howard 1986)
Monitoring Parameters - Level and frequency of monitoring associated with potassiumtherapy is dependent upon the cause and/or severity of hypokalemia, acid/baseabnormalities, renal function, and concomitant drugs administered or disease states andcan include: 1) Serum potassium ; 2) Other electrolytes; 3) Acid/base status; 4) Glucose;
5) ECG; 6) CBC; 7) Urinalyses
Dosage Forms/Preparations/FDA Approval Status/Withholding Times - Veterinary-Approved Products:
