    Sodium Correction Rate in Hyponatremia and Hypernatremia

    Calculates recommended fluid type, rate, and volume to correct hyponatremia slowly (or more rapidly if seizing).

    IMPORTANT

    This dosing tool is intended to assist with calculation, not to provide comprehensive or definitive drug information. Always double-check dosing of any drug and consult a pharmacist when necessary.

    When to Use
    Pearls/Pitfalls

    Use with the Sodium Deficit in Hyponatremia calculator which estimates the total amount of sodium that needs to be replaced.

    • The proper rate of correction of hyponatremia is important.

    • Overly rapid correction, particularly in chronic hyponatremia, can lead to osmotic demylination syndrome (ODS), previously known as central pontine myelinolysis (CPM).

    • In most cases, sodium correction should be done in an ICU setting, especially with hypertonic fluids for replacement.

    Advice

    • Correct hyponatremia carefully.
    • Use with the Sodium Deficit in Hyponatremia calculator which estimates the total amount of sodium that needs to be replaced.
    • Do not forget to correct the hyponatremia level in hyperglycemic patients with the Sodium Correction for Hyperglycemia calculator.
    • Typically, hypertonic solutions are reserved for patients who are overly symptomatic, such as those with seizures and severe neurologic deficits.
