Lithium (Systemic)

Brand name(s): Cibalith-S

Proper Use of This Medicine

Make certain your health care professional knows if you are on a low-sodium or low-salt diet. Too little salt in your diet could lead to serious side effects.

Take this medicine after a meal or snack. Doing so will reduce stomach upset, tremors, or weakness and may also prevent a laxative effect.

For patients taking the long-acting or slow-release form of lithium:

• Swallow the tablet or capsule whole.
• Do not break, crush, or chew before swallowing.

For patients taking the syrup form of lithium:

• Dilute the syrup in fruit juice or another flavored beverage before taking.

During treatment with lithium, drink 2 or 3 quarts of water or other fluids each day, and use a normal amount of salt in your food, unless otherwise directed by your doctor.

Take this medicine exactly as directed. Do not take more or less of it, do not take it more or less often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of unwanted effects.

Sometimes lithium must be taken for 1 to several weeks before you begin to feel better.

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. To help keep the amount constant, do not miss any doses and do not stop taking the medicine even if you feel better.

Dosing-

The dose of lithium will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of lithium. If your dose is different, do not change it unless your doctor tells you to do so.

The number of capsules or tablets or teaspoonfuls of syrup that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using lithium.

  • Adults and adolescents: To start, 300 to 600 milligrams three times a day.
  • Children up to 12 years of age: The dose is based on body weight. To start, the usual dose is 15 to 20 milligrams per kilogram of body weight (6.8 to 9 milligrams per pound) a day, given in smaller doses two or three times during the day.

If you miss a dose of this medicine, take it as soon as possible. However, if it is within 4 hours (about 6 hours for extended-release tablets or slow-release capsules) of your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
