RenaKare (Potassium Gluconate) Powder is prescribed to help correct low potassium levels in both cats and dogs. Potassium deficiencies are common in dogs, and they’re particularly common in cats. Your pet may lose too much potassium through his urine and through his gastrointestinal tract. Pets who don’t get enough potassium through their food may also need a potassium supplement to help regulate those levels. This powder is easy to administer, and your vet may have you mix it into your pet’s food to help prevent any stomach upset.


RenaKare is a potassium supplement for use in potassium deficient states in cats and dogs.

Possible Side Effects

May cause hyperkalemia. Do not exceed the recommended dose. Frequent patient monitoring is advised. Adverse effects include gastrointestinal irritation, muscular weakness, twitching, irritability, and cardiac conduction disturbances.

Drug & Food Interactions

Potassium salts are contraindicated in animals with hyperkalemia, severe renal impairment or failure, sever hemolytic reactions, Addison's disease, decreased gastrointestinal motility, and acute dehydration.


Use with caution in the presence of cardiac disease, particularly in digitized patients or in the presence of renal disease. Federal law restricts this drug to use by or on the order of a licensed veterinarian.

    Best stuff

    By Janie on Mar 31, 2021

    My cat Solo previously was on Renal-K potassium gel purchased at his vet’s clinic. He would hide from me poor baby. I tasted the stuff and couldn’t imagine how I could force him to take it. Very difficult to administer and adding to his food was not an option. After 3 large tubes I found this product. It is tasteless and mixing in his food is a dream. Eats it like a champ. Thank you for carrying this product NO more fingers in his mouth!

    The RenaKare powder is SO easy to give my 19-yr-old cat. I just mix it into wet food and he laps it up!

    Easy to mix in with his food

    By Debbie on Feb 8, 2021

    My kitty needed a potassium supplement and our vet suggested we try RenaKare. This formula is easy to mix in with his wet food and he doesn't seem to mind it at all. We will see how his potassium levels are in a week or two.
