Product Summary:

Prescription items are NON-RETURNABLE and NON-REFUNDABLE

Common Brand Names - Multiple manufacturers


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 AdministrationThe dose is dependent upon the age, weight and clinical condition of the patient. As reported in the literature, the dosage and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low birth weight infants, because of the increased risk of hyperglycemia/hypoglycemia. 

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.


PrecautionsAdditives may be incompatible. Consult with pharmacist, if available. When introducing additives, use aseptic technique, mix thoroughly and do not store. The presence of calcium limits their compatibility with certain drugs that form precipitates of calcium salts and also prohibits their simultaneous infusion through the same administration set as blood because of the likelihood of coagulation. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.


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. Overhydration 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.

Support his kidney function.
Lori G on Jun 25, 2019
Because it's a good product and I will not pay $40 per bag at my vet. Also my vet switched to a weird brand with the bag being very hard to read to determine levels from a sitting position while giving an anxious pet fluids. This bag is the best IMHO. It's easy to read and is well lettered. I know the plastic is bad but is recyclable by some in my community.

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.
LAURA M on Feb 5, 2018
I have a cat who's in the mid-final stages of renal failure. I use the sub q fluids to give her additional fluids to ease the stress on her kidneys.

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 500ml Bag
Lactated Ringers Injection USP 500ml Bag
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.
How to get started using the bag?
A shopper on Feb 27, 2019
BEST ANSWER: You need an "IV set" plus a needle. Press the needle onto the appropriate end of the IV set, and use the thumb wheel to pinch off the tube. Pull the white tab on the ringer to expose the port, and push the IV set's sharp end into the ringer. Hang the ringer overhead, then use the thumb wheel to allow the IV tube to fill with fluid until it comes out of the needle. Make sure the drip chamber - the widened section of the tubing - is about half filled. Squeeze the chamber and release to add more fluid. Insert the needle then use the thumb wheel to regulate drip rate. These instructions are for subcutaneous administration only. Do not attempt intravenous administration without more training! Delivery of air bubbles to a venous system can cause severe consequences.
Is this useable for humans?
Eric P on Feb 22, 2019
BEST ANSWER: I don't see why not. These bags are sterile and seem the same as can be purchased on human medical websites. However, since these need to be approved by vets and the others by your doctor, I don't see a reason to purchase these from an animal site for human use. The ones for human use are close in price, perhaps a little less expensive. You should compare the ingredients lists to make sure they are the same. I don't have any of this brand left to look at.
Hello, are these lactated ringers in bags that are DEHP-Free?
A shopper on Jul 17, 2018
BEST ANSWER: When I used the 1000cc Lactated Ringers..I used the bags because I could compress the bag to help the fluid to flow in without delay..also sometimes you can purchase a pressure bag that also helps speed up the flow
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!
