Talk to your doctor about the correct amount of fluid to take with this medicine. Some people need to drink extra fluid every day with lithium.

Swallow the extended-release tablet whole. Do not break, crush, or chew it.

Measure the oral solution with a marked measuring spoon, oral syringe, or medicine cup. A regular teaspoon may not measure the correct amount of medicine.

There are several different forms of lithium. The dose for each is different and they are used at different times of the day. Do not change the type of medicine you take without talking to your doctor first.

In order for lithium to work properly, it must be taken every day in regularly spaced doses as ordered by your doctor. This is necessary to keep a constant amount of lithium in your blood.
