How does this medication work? What will it do for me?
Lithium is used to treat manic episodes of bipolar disorder. It helps to control the symptoms of mania, which may include reduced need for sleep, poor judgment, hyperactivity, feelings of grandiosity, aggressiveness, and sometimes hostility. Lithium takes about 1 to 3 weeks before it has an effect on these symptoms. Lithium may also reduce the frequency of manic episodes if it is taken regularly.

How should I use this medication?
The usual starting dose for treatment of mania is 900 mg to 1,800 mg daily divided into 3 equal doses. The dose may be started at a lower level depending on the circumstances of the person taking the medication. The dose of lithium is usually aimed at keeping a certain level of lithium in the bloodstream. This is why lab tests are needed to monitor the levels. Once the best dose is reached, the medication may usually be taken in a single daily dose. This dose may be lower than the total of the initial 3 daily divided doses.
After the manic episode is controlled, it may be necessary to decrease the dose of lithium to avoid unwanted effects. At this point, the daily dose of lithium is between 500 mg and 1200 mg, divided into three doses.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications.
