lithium carbonate prescribing information dosing divided doses frequency
Lithium dosing frequency depends on the formulation and your prescriber's plan:
- Immediate-release lithium carbonate tablets/capsules: commonly taken 2 to 3 times daily.
- Extended-release or controlled-release tablets: often taken twice daily, and sometimes as a single nighttime dose if specifically prescribed.
The dose and frequency must be individualized using 12-hour blood lithium levels, kidney function, age, other medicines, and side effects. Do not change the schedule, skip doses, double a missed dose, or switch between immediate- and extended-release products without the prescriber’s direction. The FDA prescribing information lists usual adult regimens as divided doses, while DailyMed labeling emphasizes serum-level guided dosing.
Seek urgent medical advice for possible toxicity symptoms: worsening tremor, vomiting/diarrhea, marked drowsiness, confusion, unsteady walking, or slurred speech. Dehydration and medicines such as NSAID painkillers, ACE inhibitors, ARBs, and some diuretics can raise lithium levels.

If you miss a lithium dose:
- Take it when you remember only if it is still well before your next scheduled dose. Some lithium guidance uses a cutoff of within 3 hours of the usual dose time.
- If it is close to the next dose, skip the missed dose and take the next one at the usual time.
- Never double up or take an extra dose to compensate.
- If you miss more than one dose, or are unsure because of your particular schedule or lithium formulation, contact your pharmacist or prescriber for individualized advice.
Do not stop lithium suddenly without medical guidance. Keep your fluid and salt intake reasonably consistent, and seek urgent help if you develop toxicity symptoms such as severe tremor, vomiting or diarrhea, confusion, slurred speech, or trouble walking. The DailyMed medication guide specifically says not to double a missed dose and to contact your healthcare provider.
