This medication is used to treat manic-depressive disorder (bipolar disorder). It works to stabilize the mood and reduce extremes in behavior by restoring the balance of certain natural substances (neurotransmitters) in the brain.
Some of the benefits of continued use of this medication include decreasing how often manic episodes occur and decreasing the symptoms of manic episodes, such as exaggerated feelings of well-being, feelings that others wish to harm you, irritability, anxiousness, rapid/loud speech, and aggressive/hostile behaviors.
It is very important to have the right amount of lithium in your body. Too much lithium may lead to unwanted effects such as nausea, diarrhea, shaking of the hands, dizziness, twitching, seizures, slurred speech, confusion, or increase in the amount of urine. Tell your doctor right away if these effects occur.
There is only a small difference between the correct amount of lithium and too much lithium. Therefore, it is important that your doctor monitor you closely during treatment. Keep all medical and laboratory appointments while you are taking lithium.
