RenaPlus is a prescription medication used to help supplement potassium gluconate. Potassium is needed to maintain overall body health, and RenaPlus provides a safe and effective generic alternative to Tumil-K. It's also available in powder or gel form for easy administration. Veterinarians may use this medication to treat companion animals.

Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.


RenaPlus is used to provide your pets with the potassium they need when they suffer from hypokalemia (low blood potassium). Low potassium levels are common in pets with kidney (renal) problems and can also occur because of other medical conditions.

Possible Side Effects

RenaPlus is generally very safe when it is used as prescribed. It can cause nausea, vomiting, or diarrhea but these side effects can be minimized when given with food

Drug & Food Interactions

Interactions have been reported with enalapril, digoxin, spironolatone, and non-steroidal anti-inflammatory drugs or carprofen. Always discuss all medications and supplements with your veterinarian before giving RenaPlus.


Pets with high blood potassium levels (hyperkalemia) should not take RenaPlus. If severe kidney disease, acute dehydration, untreated Addison's disease (hypoadrenocorticism), or hemolysis (breakdown of red blood cells) is present, this supplement should not be given. Use should also be avoided in pets with constipation.

Also available in a gel.

    Easy to administer

    By Oliversmom on Nov 21, 2021

    I purchased this product because there was a manufacturer back order for the tablets. My baby boy is in kidney failure and requires potassium supplement. I was panicking that he won’t take to the powder in his wet food but he loves it and it’s much less difficult to give than the pills. I just mix it up in his k/d pate wet food and he gobbles it all up. Not only does he get his supplement but he gets a “treat” twice a day! I will be purchasing this form of potassium from here on! He loves it and I do too!

    Good product

    By Serena on Nov 19, 2021

    My kitty has CKD so the vet recommended her taking renal K. So far this is working pretty well for her. Easy to mix into her wet food.
