Uses for lactated ringer's

Lactated Ringer's injection is used to replace water and electrolyte loss in patients with low blood volume or low blood pressure. It is also used as an alkalinizing agent, which increases the pH level of the body.

Lactated ringer's is to be given only by or under the supervision of your doctor.

Before using lactated ringer's

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For lactated ringer's, the following should be considered:


Tell your doctor if you have ever had any unusual or allergic reaction to lactated ringer's or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Appropriate studies on the relationship of age to the effects of Lactated Ringer's injection have not been performed in the pediatric population. However, pediatric-specific problems that would limit the usefulness of lactated ringer's in children are not expected. Recommended doses should not be exceeded, and the patient should be carefully monitored during treatment. Safety and efficacy have not been established.


Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of Lactated Ringer's injection in the elderly. However, elderly patients are more likely to have electrolyte imbalance and age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving lactated ringer's.


There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Other medical problems

The presence of other medical problems may affect the use of lactated ringer's. Make sure you tell your doctor if you have any other medical problems, especially:

  • Alkalosis (high pH levels in the blood) or
  • Diabetes or
  • Hypercalcemia (high calcium level in the blood) or
  • Hypokalemia (low potassium levels in the blood) or
  • Kidney stones, or history of or
  • Metabolic acidosis (eg, lactic acidosis), severe—Use is not recommended.
  • Allergy to sodium lactate—Should not be used in patients with this condition.
  • Brain or nerve problems (eg, swelling in the brain) or
  • Heart problems or
  • Hypoxemia (low oxygen levels in the blood) or
  • Lung problems or

Precautions while using lactated ringer's

It is very important that your doctor check you closely to make sure that lactated ringer's is working properly. Blood and urine tests are needed to check for unwanted effects.

Children 28 days of age or younger (neonates) should not receive lactated ringer's together with ceftriaxone. Patients older than 28 days of age should not receive lactated ringer's together with ceftriaxone in the same infusion line.

Lactated ringer's may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after receiving lactated ringer's.

Lactated ringer's may cause hyponatremia (low sodium level in the blood), which can lead to acute hyponatremic encephalopathy. Check with your doctor right away if you have loss of consciousness, confusion, seizures, decreased urine output, dizziness, fast or irregular heartbeat, headache, increased thirst, muscle pain or cramps, trouble breathing, swelling of the face, ankles, or hands, or unusual tiredness or weakness.

Lactated ringer's may cause fluid overload and overhydration, which can lead to pulmonary congestion (fluid in the lungs) and swelling. Talk with your doctor right away if you have a decrease in the amount of urine output, noisy, rattling breathing, trouble with breathing, swelling of the fingers, hands, feet, or lower legs, troubled breathing at rest, or weight gain.

Lactated Ringer's injection may increase your risk of having hyperkalemia (high potassium level in the blood). Check with your doctor right away if you have stomach pain, confusion, irregular heartbeat, numbness or tingling in the hands, feet, or lips, difficulty with breathing, or weakness or heaviness of the legs.

Lactated ringer's may cause changes in the pH level of the blood, which may be life-threatening and require immediate medical attention. Talk to your doctor if you have any concerns.

Lactated ringer's may cause hypercalcemia (high calcium level in the blood). Talk with your doctor right away if you have stomach pain, confusion, depression, dry mouth, headache, incoherent speech, increased urination, loss of appetite, metallic taste in the mouth, muscle weakness, or unusual tiredness.

Lactated ringer's may affect your blood sugar levels. Check with your doctor right away if you have increased thirst or increased urination. If you notice a change in the results of your urine or blood sugar tests, or if you have any questions, talk with your doctor.
