Lithium Dose Adjustment and Target Level Calculator

Calculates lithium dosing based on creatinine clearance, serum level at steady state, target therapeutic window (0.6-1.0 mEq/L for maintenance), and acute intoxication management thresholds.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates lithium dosing based on creatinine clearance, serum level at steady state, target therapeutic window (0.6-1.0 mEq/L for maintenance), and acute intoxication management thresholds

Each component has a specific meaning:

  • Creatinine clearance — The creatinine clearance recorded for the scenario being assessed.
  • Serum level at steady state — The serum level at steady state recorded for the scenario being assessed.
  • Target therapeutic window (0 — The target therapeutic window (0 recorded for the scenario being assessed.

Note: Interpret the lithium dosing result against the thresholds and context described above.

How to Use

Enter the creatinine clearance, serum level at steady state, target therapeutic window (0 for the scenario you are assessing. Calculates lithium dosing based on creatinine clearance, serum level at steady state, target therapeutic window (0.6-1.0 mEq/L for maintenance), and acute intoxication management thresholds. Use the lithium dosing result to inform your calculation.
