🧠 Lithium Therapeutic Level Monitoring Simulator

Below the Floor — When Lithium Dosing Falls Short of Effect

Placeholder: low serum lithium rarely stabilizes mood adequately.

• 0.6 mmol/L: Target floor (placeholder threshold)
• Low dose: Typical cause (placeholder text)
• Elevated: Relapse risk (placeholder text)
• Titrate up: Fix (placeholder text)

Why levels stay low

Placeholder: dose too small or fast renal clearance.

The Sweet Spot — 0.6 to 1.0 mmol/L Maintenance Range

Placeholder: standard maintenance target for most patients.

• 0.6–1.0: Range (mmol/L maintenance)
• ~3 months: Check interval (placeholder text)
• High: Efficacy (placeholder text)
• Manageable: Side effects (placeholder text)

Maintaining steady state

Placeholder: stable dosing and hydration keep levels centered.

Upper Range — 1.0 to 1.2 mmol/L for Acute Episodes

Placeholder: higher levels sometimes needed for acute mania.

• 1.0–1.2: Range (mmol/L acute dosing)
• 4–6 weeks: Monitoring (placeholder text)
• More frequent: Side effects (placeholder text)
• Acute mania: Use case (placeholder text)

Balancing risk and benefit

Placeholder: closer monitoring offsets narrower safety margin.

Approaching Toxicity — Early Warning Signs Above 1.2 mmol/L

Placeholder: tremor, nausea and confusion signal rising toxicity.

• >1.2 mmol/L: Onset (placeholder threshold)
• Tremor, GI: Early signs (placeholder text)
• Hold dose: Action (placeholder text)
• 24–48 hrs: Recheck (placeholder text)

Recognizing early toxicity

Placeholder: symptoms appear before severe organ effects begin.

The Kidney Connection — Renal Function and Hydration Drive Toxicity

Placeholder: dehydration and kidney impairment raise lithium sharply.

• Renal only: Clearance (placeholder text)
• Level spikes: Dehydration effect (placeholder text)
• Raises level: NSAID interaction (placeholder text)
• Hydrate + labs: Safeguard (placeholder text)

Modifying factors on clearance

Placeholder: sodium, fluids and renal function shift steady state.

Placeholder: always recheck levels after illness or dehydration.
