Overview:
Sodium Acetate injection, USP 40 mEq (milliequivalents), is used to treat or prevent low sodium levels in patients who cannot drink fluids by mouth. It is added to the intravenous (IV) fluids. It can also be added to specific IV fluid mixtures when regular electrolyte solutions do not have enough of what a patient needs. Sodium Acetate and similar compounds help balance acidity in the body and can be used to treat a condition called metabolic acidosis or to make urine less acidic. The Food and Drug Administration approved Sodium Acetate in July 2020.
Available Doses and Dosage Forms:
Sodium Acetate Injection, USP (United States Pharmacopeia) (two milliequivalents per milliliter), is provided in large packages for use in pharmacies. The available sizes are 50 mL and 100 mL, containing 100 milliequivalents (mEq) and 200 mEq of Sodium Acetate, respectively, with a concentration of 16.4 percent.
For Patients:
What Is Hyponatremia?
Hyponatremia refers to an electrolyte imbalance caused due to reduced levels of total sodium content in the body fluids. It is seen in medical conditions like severe dehydration (vomiting or diarrhea), acute kidney failures, and syndrome of inappropriate antidiuretic hormone secretion (SIADH), where the body holds onto water due to an overproduction of a hormone called ADH (antidiuretic hormone). Even though the body has trouble getting rid of water, it does not have problems with handling sodium, as the usual mechanisms for controlling sodium levels are still working. Treating hyponatremia caused by SIADH depends on several factors, like low sodium levels, associated symptoms, if the SIADH can be reversed, and the concentration of certain substances in the urine.
How Does Sodium Acetate Work?
Acetate ions accept hydrogen ions in a way similar to bicarbonate and release sodium ions. These released sodium ions are crucial for patients with low sodium levels, especially those with hyponatremia. Sodium plays a major role in controlling the amount of fluid outside of cells in the body. Thus, sodium acetate helps in restoring electrolyte imbalance.
What Is the Dosage of Sodium Acetate?
-
Sodium acetate injection, USP (two mEq/mL) is mixed with a large amount of fluid (diluted) and given through a vein (intravenously). The dose of the drug and the rate of the drug given depends on the patient's needs, and doctors check the sodium levels in the blood to decide the right amount. With clean techniques, the needed amount of the drug is added to other fluids given through the vein to give the right amount of Sodium acetate.
-
Bulk packages used in pharmacies are meant to be used with manual or automated systems to mix with IV nutrition solutions. After mixing, it should be kept in the fridge and used within a day.
-
Before giving it, visually check the solution for any particles or changes in color.
How Effective Is Sodium Acetate?
Sodium Acetate is a key substance used to replace electrolytes when given through a vein. It is mainly used to fix low sodium levels in patients with hyponatremia. It can also help with metabolic acidosis and make urine less acidic.
What Are the Things to Inform the Doctor Before Taking Sodium Acetate?
-
If the person is allergic to Sodium Acetate or any of its components, or if they had any reactions to Sodium Acetate, other medications, foods, or substances, let the doctor know about it and describe what symptoms they experienced.
-
If the person has high sodium levels or swelling, they should not use Sodium Acetate.
-
It is essential to talk to the doctor and pharmacist about all the medications the person is taking, including prescriptions, over-the-counter drugs, vitamins, and natural products, as well as any health conditions they have.
-
Do not make any changes to the medication regimen without consulting the doctor first.
How Is Sodium Acetate Administered?
Sodium Acetate Injection, USP (2 mEq/mL), is given through a vein after mixing it with a larger amount of fluid. The amount and how fast it is given depend on what the patient needs. Doctors check the sodium levels in the blood to decide the right amount. The drug is administered only by a trained healthcare provider in clinical settings.

For Doctors:
Indication:
-
Sodium Acetate Injection, USP (2 mEq/mL), is used to add sodium to IV (intravenous) fluids for patients who cannot drink fluids by mouth.
-
Sodium Acetate helps prevent or fix low levels of sodium in the blood.
-
Sodium Acetate can also be added to IV fluids when regular electrolyte solutions do not provide enough sodium or nutrients for a patient's needs.
Dose: Sodium Acetate for injection, USP concentrate (four mEq/mL) comes in single-dose vials of 50 mL, and each box contains 25 vials. It should be stored at room temperature between 20 degrees Celsius to 25 degrees Celsius (68 degrees Fahrenheit to 77 degrees Fahrenheit), with allowable temperature variations between 15 degrees Celsius to 30 degrees Celsius (59 degrees Fahrenheit to 86 degrees Fahrenheit).
Pharmacological Aspects of Sodium Acetate:
-
Pharmacodynamics: Sodium is the main positively charged particle found outside of cells in the body. It makes up over 90 percent of all positive particles in the blood at a normal level of about 140 milliequivalents per liter. Sodium plays a crucial role in regulating the total amount of water in the body and where it is located. Acetate ions can take on hydrogen ions, similar to bicarbonate, helping to balance acidity in the body.
-
Mechanism of Action: It provides sodium ions, particularly for patients with low sodium levels. Sodium is crucial for controlling the volume of fluid outside cells, managing where water goes in the body, balancing fluids and electrolytes, and maintaining the right pressure in body fluids. Sodium also helps with nerve signals and muscle movements, keeping the body's acidity levels in check and allowing cells to take in nutrients.
-
Pharmacokinetics: After being given intravenously, Sodium Acetate quickly becomes available in the bloodstream. Its distribution volume and how much it binds to proteins are not known. In the liver, Sodium Acetate is broken down into bicarbonate. This process involves acetate gradually turning into carbon dioxide and water, which then combine with a hydrogen ion to form bicarbonate. Both sodium and bicarbonate are mainly removed from the body through urine. Some sodium is also eliminated in feces, and small amounts may be found in saliva, sweat, bile, and pancreatic secretions.
Toxicity:
This substance can irritate the lining of the nose, throat, and lungs, especially if breathed in. It could also be harmful if swallowed or absorbed through the skin. It might irritate the eyes, skin, or respiratory system. There is no complete information about how toxic this substance might be.
Contraindications of Sodium Acetate:
Sodium Acetate Injection, USP (2 mEq/mL), should not be used in patients who already have high sodium levels in their blood or are retaining fluids (due to certain medical conditions).
Warnings:
-
Sodium Acetate injection, USP (2 mEq/mL) needs to be mixed with another solution before it can be used. It is important to infuse solutions containing sodium slowly to avoid causing too much Sodium or water retention in the body.
-
People with certain health conditions, like congestive heart failure or severe kidney problems, should be careful with solutions containing sodium. These solutions might cause the body to hold onto too much sodium, which can lead to swelling.
-
If someone has kidney problems, giving them solutions with sodium might make them hold onto even more sodium.
-
Solutions with acetate ions should also be used carefully in people with certain conditions, like metabolic or respiratory alkalosis (a pathologically aberrant state marked by the accumulation of excess alkali or base in the body). In these conditions, too much acetate can be harmful.
-
Giving this solution too quickly can overload the body with fluid or substances, leading to diluted levels of other electrolytes in the blood, too much fluid in the body, swelling, or fluid buildup in the lungs.
-
This product contains aluminum, which can be harmful if given for a long time, especially to people with kidney problems. Premature babies are at higher risk because the kidneys are still developing, and they often need solutions that contain aluminum for their calcium and phosphate needs. Giving too much aluminum to patients with kidney problems, including premature babies, can lead to toxicity in the brain and bones. Even small amounts of aluminum given over time can cause problems.
Precautions:
-
Do not use Sodium Acetate injection or USP unless the solution is clear and the seal is intact. Any unused portion should be thrown away.
-
When giving sodium replacement therapy, doctors should primarily consider the patient's sodium levels in their blood.
-
Be cautious when giving sodium-containing solutions to patients with severe kidney problems, liver cirrhosis, heart failure, or conditions where the body retains sodium, as well as to patients with low urine output.
-
Be careful when giving parenteral fluids, especially those with sodium, to patients taking corticosteroids or corticotropin.
-
Using solutions with acetate ions too much can lead to metabolic alkalosis, so be cautious.
-
Sodium Acetate injection, USP is classified as pregnancy category C, meaning its effects on pregnancy are not fully known. It should only be given to pregnant women if necessary.
-
It is safe to use Sodium Acetate injection, USP, in infants, children, and teenagers.
-
There is not enough information to say if there are differences in how elderly patients respond to Sodium Acetate injection and USP compared to younger patients. However, because older patients are more likely to have kidney, liver, or heart problems, doctors should start with lower doses and monitor their kidney function.
-
Since sodium is mostly removed from the body through the kidneys, there might be a higher risk of side effects in patients with kidney problems, especially in the elderly. So doctors should be careful about how much sodium acetate injection and USP they give, and they might need to check kidney function regularly.
