Side Effects
6 ADVERSE REACTIONS The following adverse reactions are described in greater detail in other sections: Acute Lithium Toxicity [see Warnings and Precautions ( 5.1 )] Lithium-Induced Polyuria [see Warnings and Precautions ( 5.2 )] Hyponatremia [see Warnings and Precautions ( 5.3 )] Lithium-Induced Chronic Kidney Disease [see Warnings and Precautions ( 5.4 )] Encephalopathic Syndrome [see Warnings and Precautions ( 5.5 )] Serotonin Syndrome [see Warnings and Precautions ( 5.6 )] Hypothyroidism or Hyperthyroidism [see Warnings and Precautions ( 5.7 )] Hypercalcemia and Hyperparathyroidism [see Warnings and Precautions ( 5.8 )] Unmasking of Brugada Syndrome [see Warnings and Precautions ( 5.9 )] Pseudotumor Cerebri [see Warnings and Precautions ( 5.10 )] Common Adverse Reactions: Adult Patients...
Interactions
7 DRUG INTERACTIONS Diuretics, NSAID, renin-angiotensin system antagonists, or metronidazole may increase lithium serum concentrations. Recommend frequent monitoring of serum lithium concentration and adjust dosage when necessary. ( 2.3 , 7.1 ) Serotonergic Agents: Increased risk of serotonin syndrome when co-administered with lithium. ( 5.6 , 7.1 ) Antipsychotics: There have been reports of neurologic adverse reactions in patients treated with lithium and an antipsychotic, ranging from extrapyramidal symptoms to neuroleptic malignant syndrome.
Warnings
WARNING: LITHIUM TOXICITY 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 treatment [see Dosage and Administration ( 2.3 ), Warnings and Precautions ( 5.1 ) ]. WARNING: LITHIUM TOXICITY See full prescribing information for complete boxed warning. 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 ). 4 CONTRAINDICATIONS Lithium is contraindicated in patients with known hypersensitivity to any inactive ingredient in the lithium citrate products [see Adverse Reactions ( 6 )]. Known hypersensitivity to any inactive ingredient in the drug product. ( 4 )
Pregnancy
8.1 Pregnancy 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.
