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.
