Take this medication by mouth as directed by your doctor, usually 3 to 4 times daily for adults and 2 to 3 times daily for children. Take lithium with or right after meals to lessen stomach upset. Drink 8 to 12 glasses (8 ounces/240 milliliters each) of water or other fluid each day, and eat a healthy diet with normal amounts of salt (sodium) as directed by your doctor or dietician while taking this medication. Large changes in the amount of salt in your diet may change your lithium blood levels. Do not change the amount of salt in your diet unless your doctor tells you to do so.
The dosage is based on your medical condition, lithium blood levels, and response to treatment. Children’s dosage is also based on weight. For the best effect, take this medication regularly at evenly spaced times. To help you remember, take this medication at the same times every day.
