How does this medication work? What will it do for me?
Lithium citrate belongs to the class of medications called antimanics. Lithium is used to treat the manic episodes of bipolar disorder. It is also used to prevent or to reduce the frequency of manic episodes for people with bipolar disorder. It works by affecting the balance of chemicals that occur naturally in the brain.
Lithium starts to work within 5 to 7 days but it may take up to 3 weeks before it controls the symptoms of mania (e.g., reduced need for sleep, poor judgment, hyperactivity, feelings of grandiosity, aggressiveness, and sometimes hostility).
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here.

How should I use this medication?
The usual starting dose for treatment of mania is 600 mg to 1,800 mg daily divided into 3 equal doses. The dose may be started at a lower level depending on the circumstances of the person taking the medication. The dose of lithium is usually aimed at keeping a certain level of lithium in the bloodstream. This is why lab tests are needed to monitor the levels. Once the best dose is reached, the medication may usually be taken in a single daily dose. This dose may be lower than the total of the initial 3 daily divided doses.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue on with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue on with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children. Do not freeze this medication.

HEALTH CANADA ADVISORY
February 5, 2014
Health Canada has issued new restrictions concerning the use of lithium. To read the full Health Canada Advisory, visit Health Canada’s web site at www.hc-sc.gc.ca.
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Drowsiness/reduced alertness: Lithium may reduce mental or physical abilities. Avoid activities that require alertness, such as operating vehicles or machinery, until you know how the medication affects you.
Fluid intake and diet: The level of lithium in the blood is directly affected by the intake of fluid and salt, so it is important to maintain a normal diet, including adequate salt and fluid intake (2,500 mL to 3,000 mL). You should try to avoid making large changes to your diet that would affect your salt and fluid intake. Talk to your doctor about the appropriate amounts of fluid and salt to take.
Heart disease: People with heart disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. People with severe heart disease should not take lithium citrate (see "Who should NOT take this medication?")
Kidney disease: People with kidney disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Long-term lithium treatment is frequently associated with a decrease in kidney function as well as symptoms of thirst, excess urination, and weight gain. If you experience any of these symptoms, contact your doctor.
Lab tests: Side effects resulting from lithium are closely related to the level of lithium in the blood. The side effects can occur at doses that are close to the normal dose required for your body to respond. You will probably need to have regular blood tests while taking this medication, so your doctor can monitor the blood levels of lithium.
Stopping the medication: Do not stop taking this medication suddenly without checking with your doctor first. Stopping the medication suddenly may cause a manic episode or other withdrawal symptoms.
Thyroid disease: People with thyroid disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Long-term lithium treatment is sometimes associated with the development of growths in the thyroid gland. Contact your doctor if you develop a swelling in the neck.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking lithium citrate, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under 12 years of age.
Seniors: Seniors appear to be more likely to experience side effects when taking lithium, even if the blood levels are appropriate. Lower doses may be necessary to avoid these effects.
