Lithium (Eskalith®, Eskalith CR®, Lithobid®) is a prescription medication licensed for treating bipolar disorder. It comes in several different forms and strengths; lithium capsules are available in three strengths, tablets are available in one strength, and the syrup is available in one strength. There are also two strengths available for extended-release lithium: 450 mg and 300 mg tablets.
The recommended starting lithium dose for acute mania is 600 mg three times daily (for immediate-release tablets, capsules, or syrup). You can also take two lithium 450 mg extended-release tablets or three 300 mg extended-release tablets twice a day (for a total of lithium 900 mg twice daily). Extended-release lithium tablets should not be chewed, crushed, or broken; they should be swallowed whole.
