Lithium Toxicity Level Interpreter

Lithium Level Interpreter: Use for rapid assessment of serum lithium levels. Chronic toxicity carries higher risk at lower levels than acute ingestion.

When to Use

When to Use

Monitoring serum lithium levels in patients treated for bipolar disorder

Evaluating suspected lithium toxicity (acute, acute-on-chronic, or chronic)

Determining the need for hemodialysis or aggressive supportive care

Screening for drug-drug interactions (e.g., NSAIDs, ACE inhibitors, diuretics) that may elevate lithium levels

How it Works

Therapeutic Range

The standard therapeutic range for maintenance is 0.6–1.0 mmol/L. For acute mania, levels up to 1.2 mmol/L may be targeted.

Toxicity Thresholds

1.5–2.5 mmol/L	Mild to Moderate Toxicity
2.5–3.5 mmol/L	Severe Toxicity
> 3.5 mmol/L	Life-threatening / Hemodialysis Indicated

Acute vs. Chronic

Chronic toxicity often presents at lower serum levels than acute toxicity and carries a higher risk of permanent neurological damage (SILENT syndrome).
