🩺 Clinical
Lithium is used to treat and prevent episodes of mania (frenzied, abnormally excited mood) in people with bipolar disorder (manic-depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). Lithium is in a class of medications called antimanic agents. It works by decreasing abnormal activity in the brain.

WARNING: LITHIUM TOXICITY See full prescribing information for complete boxed warning .
Lithium toxicity is closely related to serum lithium concentrations, and can occur at doses close to therapeutic concentrations. Facilities for prompt and accurate serum lithium determinations should be available before initiating therapy ( 2.3 , 5.1 ).
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Lithium is a mood-stabilizing agent indicated as monotherapy for the treatment of bipolar I disorder: Treatment of acute manic and mixed episodes in patients 7 years and older [see Clinical Studies (14)] Maintenance treatment in patients 7 years and older [see Clinical Studies (14)] Lithium is a mood-stabilizing agent indicated as monotherapy for the treatment of bipolar I disorder: Treatment of acute manic and mixed episodes in patients 7 years and older ( 1 ) Maintenance treatment in patients 7 years and older ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Recommended starting dosage for adults and pediatric patients over 30 kg ( 2.2 ): Tablets: 300 mg, three times daily Recommended starting dosage for pediatric patients 20 to 30 kg ( 2.2 ): Tablets: 300 mg twice daily Obtain serum lithium concentration assay after 3 days, drawn 12 hours after the last oral dose and regularly until patient is stabilized ( 2.2 ). Acute Manic or Mixed Episodes (patients 7 years and older): Titrate to serum lithium concentrations 0.8 to 1.2 mEq/L ( 2.2 ). Maintenance Treatment for Bipolar I Disorder (patients 7 years and older): Titrate to serum lithium concentrations 0.8 to 1 mEq/L ( 2.2 ).
Pre-treatment Screening: Evaluate renal function, vital signs, electrolytes, thyroid function, concurrent medications, and pregnancy status ( 2.1 ). Mild to Moderate Renal Impairment (CLer 30 to 89 mL/min): Start with dosages less than those for patients with normal renal function, titrate slowly with frequent monitoring ( 2.5 ). Severe Renal Impairment (CLer<30mL/min): Avoid use of lithium ( 2.5 ).
2.1Pre-treatment Screening Before initiating treatment with lithium, renal function, vital signs, serum electrolytes, and thyroid function should be evaluated. Concurrent medications should be assessed, and if the patient is a woman of childbearing potential, pregnancy status and potential should be considered.
2.2Recommended Dosage See Table 1 for dosage recommendations for acute and maintenance treatment of bipolar I disorder in adult and pediatric patients (7 to 17 years). Obtain serum lithium concentration assay after 3 days, drawn 12 hours after the last oral dose and regularly until patient is stabilized. Fine hand tremor, polyuria, and thirst may occur during initial therapy for the acute manic phase and may persist throughout treatment.
Nausea and general discomfort may also appear during the first few days of lithium administration. These adverse reactions may subside with continued treatment, concomitant administration with food, or temporary reduction or cessation of dosage. Table 1.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Lithium-Induced Polyuria: May develop during initiation of treatment. Increases risk of lithium toxicity. Educate patient to avoid dehydration.
Monitor for lithium toxicity and metabolic acidosis. Discontinue lithium or treat with amiloride as a therapeutic agent ( 5.2 ). Hyponatremia: Symptoms are more severe with faster-onset hyponatremia.
Dehydration from protracted sweating, diarrhea, or elevated temperatures from infection increases risk of hyponatremia and lithium toxicity. Educate patients on maintaining a normal diet with salt and staying hydrated. Monitor for and treat hyponatremia and lithium toxicity, which may necessitate a temporary reduction or cessation of lithium and infusion of serum sodium ( 5.3 ).
Lithium-Induced Chronic Kidney Disease: Associated with structural changes in patients on chronic lithium therapy. Monitor kidney function during treatment with lithium ( 5.4 ). Encephalopathic Syndrome: Increased risk in patients treated with lithium and an antipsychotic.
Monitor routinely for changes to cognitive function ( 5.5 ). Hypothyroidism and Hyperthyroidism: Monitor thyroid function regularly ( 5.7 ). Hypercalcemia and Hyperparathyroidism: Associated with long-term lithium use.
Monitor serum calcium ( 5.8 ).
5.1Lithium Toxicity The toxic concentrations for lithium (≥1.5 mEq/L) are close to the therapeutic range (0.8 to 1.2mEq/L). Some patients abnormally sensitive to lithium may exhibit toxic signs at serum concentrations that are considered within the therapeutic range [see Boxed Warning, Dosage and Administration (2.3)]. Lithium may take up to 24 hours to distribute into brain tissue, so occurrence of acute toxicity symptoms may be delayed.
Neurological signs of lithium toxicity range from mild neurological adverse reactions such as fine tremor, lightheadedness, lack of coordination, and weakness; to moderate manifestations like giddiness, apathy, drowsiness, hyperreflexia, muscle twitching, ataxia, blurred vision, tinnitus, and slurred speech; and severe manifestations such as clonus, confusion, seizure, coma, and death. In rare cases, neurological sequelae may persist despite discontinuing lithium treatment and may be associated with cerebellar atrophy.
Cardiac manifestations involve electrocardiographic changes, such as prolonged QT interval, ST and T-wave changes and myocarditis. Renal manifestations include urine concentrating defect, nephrogenic diabetes insipidus, and renal failure. Respiratory manifestations include dyspnea, aspiration pneumonia, and respiratory failure.
Gastrointestinal manifestations include nausea, vomiting, diarrhea, and bloating. No specific antidote for lithium poisoning is known [see Overdosage (10)]. The risk of lithium toxicity is increased by: Recent onset of concurrent febrile illness Concomitant administration of drugs which increase lithium serum concentrations by pharmacokinetic interactions or drugs affecting kidney function [see Drug Interactions (7)] .
Acute ingestion Impaired renal function Volume depletion or dehydration Significant cardiovascular disease Changes in electrolyte concentrations (especially sodium and potassium) Monitor for signs and symptoms of lithium toxicity. If symptoms occur, decrease dosage or discontinue lithium treatment.
5.2Lithium-Induced Polyuria Chronic lithium treatment may be associated with diminution of renal concentrating ability, occasionally presenting as nephrogenic diabetes insipidus, with polyuria and polydipsia. The concentrating defect and natriuretic effect characteristic of this condition may develop within weeks of lithium initiation. Lithium can also cause renal tubular acidosis, resulting in hyperchloremic metabolic acidosis.
Such patients should be carefully managed to avoid dehydration with resulting lithium retention and toxicity. This condition is usually reversible when lithium is discontinued, although for patients treated with long-term lithium, nephrogenic diabetes insipidus may b…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Pediatric Patients (7 to 17 years) Bipolar I Disorder : The following findings are based on an 8-week, placebo-controlled study for acute manic or mixed episodes of bipolar I disorder in pediatric patients 7 to 17 years (N= 81).
In this study, lithium was administered at daily doses ranging from 300 to 3600 (mean dose 1483 mg ± 584) with serum levels ranging from 0 to 2.0 (mean level 0.98 mEq/L ± 0.47). Common Adverse Reactions (incidence ≥ 5% and at least twice the rate of placebo) : nausea/vomiting, polyuria, thyroid abnormalities, tremor, thirst/polydipsia, dizziness, rash/dermatitis, ataxia/gait disturbance, decreased appetite, and blurry vision. Adverse Reactions Occurring at an Incidence of 2% or More in Lithium-Treated Pediatric Patients : Adverse reactions associated with the use of lithium (incidence of 2% or greater, rounded to the nearest percent, and lithium incidence greater than placebo) that occurred during acute therapy (up to 8-weeks in pediatric patients with bipolar disorder) are shown in Table 3.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: May cause fetal and/or neonatal harm ( 8.1 ) Renal Impairment: Use caution during dose selection, starting with dosages less than those for patients with normal renal function while carefully monitoring for side effects ( 2.5 , 6 )
8.1Pregnancy Risk Summary Lithium may cause harm when administered to a pregnant woman. Early voluntary reports to international birth registries suggested an increase in cardiovascular malformations, especially for Ebstein’s anomaly, with first trimester use of lithium. Subsequent case-control and cohort studies indicate that the increased risk for cardiac malformations is likely to be small; however, the data are insufficient to establish a drug-associated risk.
There are concerns for maternal and/or neonatal lithium toxicity during late pregnancy and the postpartum period [see Clinical Considerations]. Published animal developmental and toxicity studies in mice and rats report an increased incidence of fetal mortality, decreased fetal weight, increased fetal skeletal abnormalities, and cleft palate (mouse fetuses only) with oral doses of lithium that produced serum concentrations similar to the human therapeutic range. Other published animal studies report adverse effects on embryonic implantation in rats after lithium administration.
Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population(s) is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Clinical Considerations Dose Adjustments During Pregnancy and the Postpartum Period: If the decision is made to continue lithium treatment during pregnancy, serum lithium concentrations should be monitored and the dosage adjusted during pregnancy. Two to three days prior to delivery, lithium dosage should be decreased or discontinued to reduce the risk of maternal and/or neonatal toxicity. Lithium may be restarted in the post-partum period at preconception doses in medically stable patients as long as serum lithium levels are closely monitored [see Dosage and Administration (2.4), Warnings and Precautions (5.1)].
Fetal/Neonatal Adverse Reactions: Lithium toxicity may occur in neonates who were exposed to lithium in late pregnancy. A floppy baby syndrome including neurological, cardiac, and hepatic abnormalities that are similar to those seen with lithium toxicity in adults have been observed. Symptoms include hypotonia, respiratory distress syndrome, cyanosis, lethargy, feeding difficulties, depressed neonatal reflexes, neonatal depression, apnea, and bradycardia.
Monitor neonates and provide supportive care until lithium is excreted and toxic signs disappear, which may take up to 14 days. Consider fetal echocardiography between 16 and 20 weeks gestation in a woman with first trimester lithium exposure because of the potential increased risk of cardiac malformations.
8.2Lactation Risk Summary Limited published data reports the presence of lithium carbonate in human milk with breast milk levels measured at 0.12 to 0.7 mEq or 40 to 45% of maternal plasma levels. Infants exposed to lithium during breastfeeding may have plasma levels that are 30 to 40% of maternal plasma levels. Signs and symptoms of lithium toxicity such as hypertonia, hypothermia, cyanosis, and ECG changes have been reported in some breastfed neonates and infants.
Increased prolactin levels have been measured in lactating women, but the effects on milk production are not known. Breastfeeding is not recommended with maternal lithium use; however, if a woman chooses to breastfeed, the infant should be closely monitored for signs of lithium toxicity. Discontinue breastfeeding if a breastfed infant develops lithium toxicity.
Clinical Considerations Consider regular monitoring of lithium levels and thyroid function in a breastfed inf…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of lithium for monotherapy treatment of acute manic or mixed episodes of bipolar I disorder and maintenance monotherapy of bipolar I disorder in pediatric patients ages 7 to 17 years of age have been established in an acute-phase clinical trial of 8 weeks in duration followed by a 28-week randomized withdrawal phase [see Dosage and Administration (2.1), Adverse Reactions (6.1), Clinical Pharmacology (12.3), Clinical Studies (14)]. The safety and effectiveness of lithium has not been established in pediatric patients less than 7 years of age with bipolar I disorder.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of lithium carbonate tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other treatment.
Lithium is known to be substantially excreted by the kidneys, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.
🆘 Overdosage ▾
10 OVERDOSAGE The toxic concentrations for lithium (≥ 1.5 mEq/L) are close to the therapeutic concentrations [see Warnings and Precautions (5.1)] . At lithium concentrations greater than 3 mEq/L, patients may progress to seizures, coma, and irreversible brain damage. Treatment For current information on the management of poisoning or overdosage, contact the National Poison Control Center at 1800-222-1222 or www.poison.org.
No specific antidote for lithium poisoning is known. Mild symptoms of lithium toxicity can usually be treated by reduction in dose or cessation of the drug. In severe cases of lithium poisoning, the goal of treatment is elimination of this ion from the patient.
Administration of gastric lavage should be performed, but use of activated charcoal is not recommended as it does not significantly absorb lithium ions. Hemodialysis is the treatment of choice as it is an effective and rapid means of removing lithium in patients with severe toxicity. As an alternative option, urea, mannitol and aminophylline can induce a significant increase in lithium excretion.
Appropriate supportive care for the patient should be undertaken. Patients with impaired consciousness should have their airway protected and it is critical to correct any volume depletion or electrolyte imbalance. Patients should be monitored to prevent hypernatremia while receiving normal saline and careful regulation of kidney function is of utmost importance.
Serum lithium concentrations should be closely monitored as there may be a rebound in serum lithium concentrations as a result of delayed diffusion from the body tissues. Likewise, during the late recovery phase, lithium should be re-administered with caution taking into account the possible release of significant lithium stores in body tissues.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism of action of lithium as a mood stabilizing agent is unknown.
12.3Pharmacokinetics Absorption After oral administration, lithium is reported to be completely absorbed in the upper gastrointestinal tract. Peak serum concentrations (T max ) occur 0.25 to 3 hours after oral administration of immediate release preparations and 2 to 6 hours after sustained-release preparations. Distribution The distribution space of lithium approximates that of total body water, and the plasma protein binding is negligible.
After equilibrium, the apparent volume of distribution is 0.7 to 1 L/kg. Metabolism Lithium is not metabolized. Excretion Lithium is primarily excreted in urine, proportionally to its serum concentration.
Lithium is filtered by the glomerulus, and 80% is reabsorbed by passive diffusion in the proximal tubule. The elimination half-life of lithium is approximately 18 to 36 hours. Lithium excretion in feces is insignificant.
Specific Populations Pediatric Use : A pharmacokinetic study of lithium was performed in 39 subjects with bipolar I disorder. Both apparent clearance and apparent volume of distribution increase as body weight increases. A lower dose in patients < 30 kg is necessary to achieve lithium exposures in pediatric patients similar to those observed in adults treated at recommended doses of lithium [ see Dosage and Administration (2.2)] .
The estimated plasma clearance was
0.59 L/h,
0.79 L/h and
1.17L/h for pediatric patients weighing 20 kg, 30 kg and 50 kg, respectively.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read FDA-approved patient labeling (Medication Guide). Dosage and Administration Advise patients that lithium is a mood stabilizer, and should only be taken as directed. Emphasize the importance of compliance with the prescribed treatment and to not adjust the dose of lithium without first consulting their healthcare provider.
Inform patients that they will need to have regular blood draws to determine if their dose of lithium is appropriate. Instruct patients not to double the dose if a dose is missed, due to the complexity of individualized dosing and potential for lithium toxicity [see Dosage and Administration (2), Warnings and Precautions (5.1 )]. Lithium Toxicity Inform patients on adverse reactions related to lithium toxicity that require medical attention.
Advise patients to discontinue lithium treatment and contact their healthcare provider if clinical signs of lithium toxicity such as diarrhea, vomiting, tremor, lack of muscle coordination, drowsiness, abnormal heart rhythm or muscular weakness occur [see Warnings and Precautions (5.1)] . Lithium-Induced Polyuria Counsel patients on the adverse reactions related to lithium-induced polyuria, when to seek medical attention, and the importance of maintaining normal diet with salt and staying hydrated [see Warnings and Precautions (5.2)] .
Hyponatremia Counsel patients on the adverse reactions of hyponatremia, when to seek medical attention, the importance of maintaining a normal diet including adequate salt intake and staying hydrated [see Warnings and Precautions (5.3)] . Salt supplements and additional fluids may be required if excessive losses occur. Serotonin Syndrome Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of lithium with other serotonergic drugs including SSRIs, SNRIs, triptans, tricyclic antidepressants, fentanyl, tramadol, tryptophan, buspirone, St.
John’s Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid) [see Warnings and Precautions (5.6) and Drug Interactions (7)] . Drug Interactions Advise patients that many drugs can interact with lithium and to inform their doctor and pharmacist if they are taking any over the counter medication, including herbal medication, or are started on a new prescription [see Drug Interactions (7)] . Somnolence Tell patients that lithium may cause somnolence particularly when initiating treatment and to be cautious about operating vehicles or hazardous machinery, until they are reasonably certain that lithium treatment does not affect them adversely [see Adverse Reactions (6)] .
Pregnancy Advise pregnant women of the potential risk to a fetus and/or neonate [see Use in Specific Populations (8.1)]. Lactation Advise women that breastfeeding is not recommended during treatment with lithium [see Use in Specific Populations (8.2)].
