RenaPlus is a supplement prescribed by veterinarians to provide extra potassium to pets who have low levels due to kidney disease or other medical problems. Potassium is an electrolyte that helps nerves communicate and maintains muscle movement. This generic alternative is an easy-to-feed tablet that aids in returning your pet's body to its normal functions.


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

May cause nausea, vomiting, or diarrhea, especially if not given with food.

Drug & Food Interactions

Talk to your veterinarian about any other drugs your dog is taking before starting this medication.


Do not use in pets with hyperkalemia (high potassium blood levels), severe kidney disease, acute dehydration, untreated Addison's disease, or hemolysis (breakdown of red blood cells). Use should also be avoided in pets with constipation or heart disease, especially when taking Digoxin.

    Large pill, can cut in half!

    By BustersMom on Mar 12, 2021

    Our geriatric kitty, Buster, must have potassium supplements due to his heart condition. I have been giving him 1 teaspoon of RenaPlus in gel form, twice a day. I am able to place it in his mouth in 3 applications, but he does not like it! I started giving him these pills (1 pill is equivalent to 1 teaspoon gel), but they are quite large. I received the "okay" to cut the pills in half. I administer each half followed with a squirt of water in a syringe.
