Typical dosage for Potassium Chloride

Your provider will determine your dose of Potassium Chloride (measured in milliequivalents, or mEq) based on different factors, such as your blood potassium level and what medical conditions you have.

Potassium Chloride comes in different forms, including extended-release capsules, extended-release tablets, and oral solutions. Your dose might differ depending on what formulation you're prescribed.

In general:

  • Treatment of low potassium level

    • Adults: The typical total daily dose ranges from 40 mEq to 100 mEq, split into 2 to 5 smaller doses and taken by mouth throughout the day. Don't take more than 20 mEq (for tablets) or 40 mEq (for capsules and oral solutions) for any single dose.
    • Children (ages 16 years and younger): Your child's provider will determine the dose based on your child's body weight. The typical total daily dose ranges from 2 mEq/kg to 4 mEq/kg, split into smaller doses and taken by mouth throughout the day.
  • Prevention of low potassium level

    • Adults: The typical dose is to take 20 mEq by mouth daily.
    • Children (ages 16 years and younger): Your child's provider will determine the dose based on your child's body weight. The typical dose is to take 1 mEq/kg by mouth daily.
