If you have bipolar disorder, your healthcare provider may recommend lithium (Eskalith^®, Eskalith CR^®, Lithobid^®). Although the drug cannot cure bipolar disorder, it can help to control the symptoms. It is not exactly clear how the medication works, but it is thought to work by affecting various chemicals in the brain called neurotransmitters. Lithium comes in several forms, including tablets, extended-release tablets, capsules, and syrup. The dosage of lithium that your healthcare provider prescribes will depend on how you respond to lithium, the particular product being used, other medical conditions you may have, among other things.
