How long does it take for lithium carbonate to be effective for bipolar ii symptoms? and what is theraputic level? thanks.

Depends.: The therapeutic level of lithium is 0.6 to 1.2 meq/l. The effectivity should be seen within a week at a therapeutic level. Often, depending on the symptoms of bipolar disorder , such as depression, mania or psychotic behavior, antipsychotic medications antidepressants and minor tranquilizers are given concomittantly especially during the acute stages of either mania or depression.

Varies: Onset of benefit can occur in days. This is very welcomed when this occurs but it is not discouraging if it doesn't. Depend end on a patients course of illness benefit from lithium can be realized over a few to several weeks. Therapeutic blood levels for lithium range from 0.5 to 1.2 meq/l.
