What is the effective daily dosing range for Lithium?

The effective daily dosing range for Lithium typically falls within 900-1800 mg/day for the treatment of bipolar disorder. This range is supported by clinical guidelines and research that have established the efficacy of Lithium in stabilizing mood and reducing the frequency and severity of manic and depressive episodes in patients with bipolar disorder.

At dosages lower than this range, such as those found in the first option or the second option, the therapeutic effects may not be fully realized, and patients may not achieve the necessary serum levels of Lithium needed for adequate mood stabilization. Likewise, while the highest range suggested might seem plausible initially, it is typically reserved for specific instances or for individuals with particular health circumstances and often monitored closely to avoid toxicity.

Therefore, 900-1800 mg/day is recognized as the standard effective dose that balances benefits with the risk of side effects, hence making it the accurate answer in this context.
