Product Summary:

Common Drug Name

Lactated Ringer's Injection (LRS)


Common Brand Names - Multiple manufacturers; no specific brand names.


Storage - Store in manufacturer's packaging at room temperature.


Uses - Used to maintain hydration or to rehydrate animals in many situations including the treatment of shock, decreased oral fluid intake, and to replace fluids lost due to an illness such as kidney disease.


Dose and Administration - Always follow the dosage instructions provided by your veterinarian. If you have difficulty administering this medication, contact your veterinarian. Dosage varies tremendously depending on pet's size and health, reason for use, and route of administration. LRS can be given to animals intravenously (IV) or subcutaneously (SQ, subQ, under the skin). The route depends on the animal's size and illness or reason for use. Always administer using a new, sterile needle. If you miss a dose, contact your veterinarian. This medication should only be given to the pet for whom it was prescribed.


Possible Side Effects - Side effects are unlikely if the proper dose is given. Abscesses or infection may occur at the injection site if a sterile needle and proper technique were not used during administration. If your pet experiences an allergic reaction to the medication, signs may include facial swelling, hives, scratching, sudden onset of diarrhea, vomiting, shock, seizures, pale gums, cold limbs, or coma. If you observe any of these signs, contact your veterinarian immediately.


Precautions - Not for use in animals who are hypersensitive (allergic) to any of the ingredients. Use with extreme care in animals with heart disease, kidney disease, or obstruction of the urinary tract, since over hydration may more easily occur in these animals (see Signs of Toxicity/Overdose). Not to be used in animals whose kidneys are not producing urine. Consult with your veterinarian regarding the physical examinations and laboratory testing necessary prior to and during treatment with Lactated Ringer Injection.


Drug, Food, and Test Interactions - Consult your veterinarian before using lactated ringer injection with any other medications, including vitamins and supplements, since interactions may occur. Some injectable medications are not compatible with the components in LRS. Consult with your veterinarian before adding any medications to the bag of LRS. No known food interactions.


Signs of Toxicity/Overdose - If an animal becomes overhydrated (too much fluid is given), blood potassium levels may become too low, causing muscle and heart abnormalities. Signs may include weakness, constipation, rapid breathing, and increased heart rate. Over hydration may also cause fluid to accumulate in the lungs (pulmonary edema) and increase the workload for the heart. Signs may include increased or rapid breathing, coughing, or wheezing. If you notice any of these signs, stop fluid therapy and contact your veterinarian immediately.


** This information may not cover all possible uses, directions, side effects, precautions, allergic reactions, drug interactions, or withdrawal times. Always consult your own veterinarian for specific advice concerning the treatment of your pet.

Great product, great price!
I got this for my 17 year old cat, with kidney disease. The vet has me injecting her with fluids every other day. She’s doing so much better because of this. The quality of these bags and the solution is comparable to the ones I get from the vet. The great thing is that the price is so much lower through kvsupply. I was paying $25 a bag from the vet. I would definitely recommend this product to anyone that wants to improve their pet’s life.

My Cat with Kidney Disease is Improving on This!
This is perfect for my cat with kidney disease. Medical research has shown that humans with kidney disease who are given sodium chloride fluid in the hospital (saline) have a higher death rate than those given a balanced IV fluid, like Lactated Ringers solution or Plasma Lyte. I don't know if any research has been done on animals, but my cat was on sodium chloride IV fluid at the vet's office; after I switched to Lactated Ringers for subcutaneous fluid at home, my cat began to show signs of improvement. It's slow going, and I know that one day her kidneys will fail, but in the meantime, this fluid is doing a great job of flushing the toxins from her bloodstream and replenishing her electrolytes at the same time.

Bought a dozen bags (not bottles) of 1000ml Lactated Ringers. KV Supply (pharmacy) called my vet for the prescription & shipped it within 2 days. When it arrived soon after, it was packed wonderfully in a large foam "cooler" box within a larger cardboard box. Everything was in perfect order! We are amazed that KV is able to sell such an important item at such a GREAT VALUE so EFFICIENTLY! Amazing! We highly recommend ordering from KV. Their service is great! Our kitty Elliott agrees!!

Product as described. Cheaper then buying from vet office.
Bought the Lactated Ringers bags for subcutaneous fluids. I have a cat in renal failure who uses this fluid. Product was much cheaper then buying single bags from my vet. Product as described and I would recommend. Only issue was time it took to get approval from my vet and shipping time. Next time I may pay more for quicker shipping method.

Only option I had without dextrose.
Wayne M on Feb 9, 2018
My 16-year-old cat was diagnosed with kidney disease a month ago. The fluids (along with a renal support diet) help flush out the toxins which her kidneys can no longer do alone. Her back-leg strength has increased enough on the fluids and diet combined that she can climb up on the bed now (using "steps" I put together), which is her favorite place to be. She can also get back down safely without hurting herself.

Dog - kidney failure
Patrice M on Sep 27, 2017
My dog has renal failure and this is keeping her alive, energetic, and happy during her last days. A vet has to prescribe it and show you how to use it, but it gives them energy and strength during their declining days. I am happy to have more time with her and very happy that she can feel pretty good during this time.

is this in a bottle or bag?
A shopper on Sep 23, 2017
BEST ANSWER: You would use the drop-down box to indicate your preference of bottles or bags.
what difference in Lactated Ringer without Dextrose ?
A shopper on Nov 15, 2017
Lactated Ringers Injection USP 1000ml Bottle
Lactated Ringers Injection USP 1000ml Bottle
Lactated Ringer with Dextrose 1000ml
Lactated Ringer with Dextrose 1000ml
BEST ANSWER: From my research, it is not recommended to administer lactated ringer’s with dextrose subcutaneously. The dextrose is sugar which can result in infection at the site of injection or severe skin irritation resulting in possible necrosis (dead tissue). Check with your vet. I use lactated ringers without dextrose for my cat with renal insufficiency.
Do I need a perscription for lactated ringers solution ?
A shopper on Apr 14, 2018
BEST ANSWER: Yes, you will need a prescription for Lactated Ringers..from your vet, who suggested that you use it for your pet..I use the plastic bags for the administration of the lactated Ringers. You do not need a vet's order for the IV tubing or the needles.
The picture shows a bottle but I need the bag. Do you still sell the bag?
Mary J on Sep 29, 2017
BEST ANSWER: We do sell the bags. We will no longer be carrying the bottles.
Can B12 and potassium be added to the bag for an extra cost?
Jennifer on Sep 15, 2017
BEST ANSWER: At this time we do not offer that service.
Do I need a prescription to buy lactate ringers and the supplies?
Jennie on Aug 2, 2017
BEST ANSWER: The lactated ringers are a prescription item and do require a prescription from your vet. The intravenous sets do not.
why does this say 'veterinary' lactated ringers rather than just plain lactated ringers?
diane m on Jul 26, 2017
BEST ANSWER: Hi there,

This easiest way to explain it is that these can be dispensed by veterinarians because of labeling it this way. Hope this helps!
