Potassium Acetate and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Potassium Acetate falls into category C:

In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans, though. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.


There are no well-controlled studies that have been done in pregnant women. Potassium Acetate should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.


No studies have been done in animals, and no well-controlled studies have been done in pregnant women. Potassium Acetate should be given to a pregnant woman only if clearly needed.

  • Tell all of your health care providers that you take this medicine. This includes your doctors, nurses, pharmacists, and dentists.
  • Have blood work checked as you have been told by the doctor. Talk with the doctor.
  • You may need to have an ECG checked before starting potassium acetate and while taking it. Talk with your doctor.
  • If you are taking a salt substitute that has potassium, potassium-sparing diuretics, or potassium, talk with your doctor.
  • This medicine may contain aluminum. There is a chance of aluminum toxicity if you are on this medicine for a long time. The risk is greater if you have kidney problems. The risk is also higher in premature infants. Talk with the doctor.

Potassium Acetate - Clinical Pharmacology

Potassium is found in low concentration in plasma and extracellular fluids. It is the chief cation of body cells, and is concerned with the maintenance of the body fluid composition and electrolyte balance. The major amount of potassium is excreted in the urine. Therefore, the kidney normally determines potassium balance.

The acetate ion is completely metabolized in the body, providing a source of hydrogen ion acceptors.


Potassium Acetate Injection, USP, administration is contraindicated in diseases where high potassium levels may be encountered.

Dosing Adult

IV doses should be incorporated into the patient's maintenance IV fluids, intermittent IV potassium administration should be reserved for severe depletion situations and requires ECG monitoring; doses listed as mEq of potassium

Treatment of hypokalemia: IV: 40-100 mEq/day

IV intermittent infusion (must be diluted prior to administration):

5-10 mEq/dose (maximum: 40 mEq/dose) to infuse over 2-3 hours (maximum: 40 mEq over 1 hour)

Note: Continuous cardiac monitor recommended for rates >0.5 mEq/kg/hour

Potassium dosage/rate of infusion guidelines:

Serum potassium >2.5 mEq/L: Maximum infusion rate: 10 mEq/hour; maximum concentration: 40 mEq/L; maximum 24-hour dose: 200 mEq

Serum potassium <2.5 mEq/L: Maximum infusion rate: 40 mEq/hour; maximum concentration: 80 mEq/L; maximum 24-hour dose: 400 mEq
