Lithium carbonate: immediate-release capsules (150 mg, 300 mg, 600 mg) and tablets (300 mg); extended-release tablets (300 mg, 450 mg). Lithium citrate: oral solution (8 mEq/5 mL, equivalent to 300 mg lithium carbonate per 5 mL) for patients unable to swallow tablets. (1)

No defined absolute maximum; dosing is guided by serum level monitoring. Levels above 1.5 mEq/L carry increasing toxicity risk. Levels consistently above 1.2 mEq/L are generally not maintained in clinical practice.'"`UNIQ--ref-00000052-QINU`"' (1)

Antimanic effects begin within 5-7 days of reaching therapeutic serum levels, with full response often requiring 2-3 weeks. For acute mania, a neuroleptic is typically added for rapid sedation while lithium takes effect.'"`UNIQ--ref-00000053-QINU`"' (1)
