400 mg/day (bipolar monotherapy); 700 mg/day (epilepsy with enzyme-inducing comedication) (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)
routes:
onset:
Antiepileptic effect within days at therapeutic level; mood-stabilizing effect emerges over weeks (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)
