Lithium Level Toxicity Risk Calculator

Assess lithium toxicity risk based on serum level (12h post-dose), renal function, dehydration, NSAID/ACE inhibitor co-prescription, and clinical symptoms of intoxication.

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

Assess lithium toxicity risk based on serum level (12h post-dose), renal function, dehydration, NSAID/ACE inhibitor co-prescription, and clinical symptoms of intoxication

Each component has a specific meaning:

  • Serum level — The serum level recorded for the scenario being assessed.
  • Renal function — The renal function recorded for the scenario being assessed.
  • Dehydration — The dehydration recorded for the scenario being assessed.
  • NSAID/ACE inhibitor co-prescription — The nsaid/ace inhibitor co-prescription recorded for the scenario being assessed.
  • Clinical symptoms of intoxication — The clinical symptoms of intoxication recorded for the scenario being assessed.

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

How to Use

Enter the serum level, renal function, dehydration, NSAID/ACE inhibitor co-prescription, clinical symptoms of intoxication for the scenario you are assessing. Assess lithium toxicity risk based on serum level (12h post-dose), renal function, dehydration, NSAID/ACE inhibitor co-prescription, and clinical symptoms of intoxication. Use the lithium toxicity risk result to inform your calculation.
