Eskalith (lithium carbonate) Full Prescribing Information

Why is Lithium prescribed?

Eskalith is used to treat the manic episodes of manic-depressive illness, a condition in which a person's mood swings from depression to excessive excitement. A manic episode may involve some or all of the following symptoms:
Fast, urgent talking
Frenetic physical activity
Grandiose, unrealistic ideas
Little need for sleep
Poor judgment

Once the mania subsides, Eskalith treatment may be continued over the long term, at a somewhat lower dosage, to prevent or reduce the intensity of future manic episodes.

Some doctors also prescribe lithium for premenstrual tension, eating disorders such as bulimia, certain movement disorders, and sexual addictions.

Most important fact about Lithium

If the Eskalith dosage is too low, you will derive no benefit; if it is too high, you could suffer lithium poisoning. You and your doctor will need to work together to find the correct dosage. Initially, this means frequent blood tests to find out how much of the drug is actually circulating in your bloodstream. As long as you take Eskalith, you will need to watch for side effects. Signs of lithium poisoning include vomiting, unsteady walking, diarrhea, drowsiness, tremor, and weakness. Stop taking the drug and call your doctor if you have any of these symptoms.


How should you take Lithium?

To avoid stomach upset, take Eskalith immediately after meals or with food or milk.

Do not change from one brand of lithium to another without consulting your doctor or pharmacist. Take the drug exactly as prescribed.


While taking Eskalith, you should drink 10 to 12 glasses of water or fluid a day. To minimize the risk of harmful side effects, eat a balanced diet that includes some salt and lots of liquids. If you have been sweating a great deal or have had diarrhea, make sure you get extra liquids and salt.

If you develop an infection with a fever, you may need to cut back on your Eskalith dosage or even quit taking it temporarily. While you are ill, keep in close touch with your doctor.

Long-acting forms of lithium, such as Eskalith CR or Lithobid, should be swallowed whole. Do not chew, crush, or break.
