Lithium was popular as a health supplement before it gained recognition as a medicine, as this spring water ad shows
The sooner you start and titrate lithium for bipolar, the shorter the hospital stay
STUDY: Cordell WG et al, Ment Health Clin 2026;16(3)
STUDY TYPE: Retrospective cohort study
FUNDING: Independent
Background
Lithium is the gold standard for bipolar disorder, yet clinicians often titrate it slowly out of concern for toxicity. In an inpatient setting, where monitoring is close and symptoms are severe, the question is whether faster titration gets patients home faster.
The Study
- 68 adults admitted to an acute inpatient psychiatric unit with a manic, depressive, mixed, or hypomanic episode from bipolar disorder or schizoaffective disorder.
- Three prescribing factors were compared: lithium started within 48 hours of admission, a therapeutic-level-producing dose reached within 48 hours, and intensive initial dosing (900 mg/day or more).
Results
Starting lithium within 48 hours was associated with a lower hospital stay: from 13.4 days to 7.2 days. Reaching a therapeutic dose within 48 hours was further linked to lower days, down to 6.2 days versus 9.1 days for those who didn’t. Intensive initial dosing made no difference (in line with a new trial of lithium loading dose).
Limitations
Small, single-center, retrospective, non-randomized study. Over half the patients were discharged without reaching a therapeutic lithium level. Affective state altered length of stay independently, adding a confound.
Practice Implications
- Consider lithium sooner in hospitalized bipolar.
- Lithium also prevents rehospitalization better than other psychotropics, both in unipolar and bipolar depression.
