Dermatologic: Drying and thinning of hair, alopecia, anesthesia of skin, chronic folliculitis, xerosis cutis, psoriasis onset or exacerbation, generalized pruritus with or without rash, cutaneous ulcers, angioedema, drug reaction with eosinophilia and systemic symptoms (DRESS)
Warnings
Black Box Warnings
Toxicity is closely related to serum lithium concentrations and may occur at dosages close to therapeutic levels; monitor therapy by measuring serum lithium
Equipped facilities should be identified before initiation of therapy to provide prompt and accurate serum lithium concentration data
Contraindications
Documented hypersensitivity
Severe cardiovascular disease
Pregnancy in 1st trimester
Unstable renal function, sodium depletion, severe dehydration
Severe debilitation
Cautions
Cardiovascular disease; reports of possible association between lithium treatment and unmasking of Brugada syndrome (abnormal ECG and risk of sudden death)
Use with caution in patients with thyroid disease
Narrow therapeutic index
Risk of nephrogenic diabetes insipidus; such patients should be carefully managed to avoid dehydration with resulting lithium retention and toxicity; condition is usually reversible when lithium is discontinued
Lithium-sensitive patients may experience toxicity symptoms with serum lithium concentrations of 1-1.5 mEq/L
Lithium toxicity is closely related to serum levels and can occur at therapeutic dosages; if manifestations of toxicity occur, discontinue for 24-48 hours, then resume at lower dosage
Mainitain geriatric patients on dosages that produce serum lithium concentrations at lower end of desired range
May cause central nervous system (CNS) depression and impair ability to operate heavy machinery
Hypercalcemia reported with or without hyperparathyroidism; women and older patients are possibly at greater risk; onset does not appear to be associated with duration of therapy
Monitor changes in renal function; chronic therapy may diminish renal concentrating ability; usually reversible when lithium therapy discontinued
Use caution in debilitated patients; may increase risk of lithium toxicity
Use with caution in patients at risk for suicide
Cases consistent with nephrotic syndrome reported with use of lithium; discontinuation of lithium in patients with nephrotic syndrome has resulted in remission of nephrotic syndrome
Routine urinalysis and other tests may be used to evaluate tubular function (e.g., urine specific gravity or osmolality following a period of water deprivation, or 24-hour urine volume) and glomerular function (e.g., serum creatinine ,creatinine clearance, or proteinuria); during lithium therapy, progressive or sudden changes in renal function, even within normal range, indicate the need for re-evaluation of treatment
An encephalopathic syndrome (characterized by weakness, lethargy, fever, tremulousness and confusion, extrapyramidal symptoms, leukocytosis, elevated serum enzymes, BUN, and FBS) has reported in a few patients treated with lithium plus a neuroleptic, most notably haloperidol; in some instances, the syndrome was followed by irreversible brain damage; because of possible causal relationship patients receiving such combined therapy or patients with organic brain syndrome or other CNS impairment should be monitored closely for early evidence of neurologic toxicity and treatment discontinued promptly if such signs appear; encephalopathic syndrome may be similar to or the same as Neuroleptic Malignant Syndrome (NMS)
Lithium may prolong effects of neuromuscular blocking agents; neuromuscular blocking agents should be given with caution to patients receiving lithium
Lithium toxicity
- The risk of lithium toxicity is increased in patients with significant renal or cardiovascular disease, severe debilitation or dehydration, or sodium depletion, and for patients receiving prescribed medications that may affect kidney function, such as angiotensin converting enzyme inhibitors (ACE inhibitors), angiotensin receptor blockers (ARBs), diuretics (loops and thiazides) and NSAIDs; for these patients, consider starting with lower doses and titrating slowly while frequently monitoring serum lithium concentrations and signs of lithium toxicity
- 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; severe manifestations such as clonus, confusion, seizure, coma, and death may occur; 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 known
- Monitor for signs and symptoms of toxicity; if symptoms occur, decrease dosage or discontinue lithium treatment
Serotonin syndrome
- Lithium can precipitate serotonin syndrome, a potentially life-threatening condition; risk is increased with concomitant use of other serotonergic drugs (including selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors, triptans, tricyclic antidepressants, fentanyl, tramadol, tryptophan, buspirone, and St. John’s Wort) and with drugs that impair metabolism of serotonin, eg, MAOIs
- Monitor all patients taking lithium for emergence of serotonin syndrome; discontinue treatment with lithium and any concomitant serotonergic agents immediately if above symptoms occur and initiate supportive symptomatic treatment; if concomitant use of lithium with other serotonergic drugs is clinically warranted, inform patients of increased risk for serotonin syndrome and monitor for symptoms

LITHIUM CONTROLLED-RELEASE - ORAL
(LITH-ee-um)
COMMON BRAND NAME(S): Eskalith CR, Lithobid
WARNING: It is very important to have the right amount of lithium in your body. Too much lithium may lead to unwanted effects such as nausea, diarrhea, shaking of the hands, dizziness, twitching, seizures, trouble speaking, confusion, or increase in the amount of urine. Tell your doctor right away if these effects occur.There is only a small difference between the correct amount of lithium and too much lithium. It is important that your doctor monitor you closely during treatment. Keep all medical and laboratory appointments while you are taking lithium.
USES: This medication is used to treat manic-depressive disorder (bipolar disorder). It works to stabilize the mood and reduce extremes in behavior by restoring the balance of certain natural substances (neurotransmitters) in the brain.Some of the benefits of continued use of this medication include decreasing how often manic episodes occur and decreasing the symptoms of manic episodes such as exaggerated feelings of well-being, feelings that others wish to harm you, irritability, anxiousness, rapid/loud speech, and aggressive/hostile behaviors.
HOW TO USE: There are different brands of this medication available. They may not have the same effects. Do not change brands without asking your doctor or pharmacist.Take this medication by mouth as directed by your doctor, usually 2-3 times daily. Take lithium with or immediately after meals to lessen stomach upset. Do not crush or chew this medication. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.Drink 8 to 12 glasses (8 ounces or 240 milliliters each) of water or other fluid each day, and eat a healthy diet with normal amounts of salt (sodium) as directed by your doctor or dietician while taking this medication. Large changes in the amount of salt in your diet may change your lithium blood levels. Do not change the amount of salt in your diet unless your doctor tells you to do so.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. The dosage is based on your medical condition, lithium blood levels, and response to treatment. This medication works best if the amount of the drug in your body is kept at a constant level. Take this drug at evenly spaced intervals.This medication must be taken exactly as prescribed. Keep taking lithium even if you feel well. Do not stop taking this drug without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Consult your doctor or pharmacist for more details.Tell your doctor if your condition does not improve or if it worsens. It may take 1 to 3 weeks to notice improvement in your condition.
SIDE EFFECTS: See also Warning section.Drowsiness, dizziness, tiredness, increased thirst, increased frequency of urination, weight gain, and mildly shaking hands (fine tremor) may occur. These should go away as your body adjusts to the medication. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: diarrhea, vomiting, unsteady walk, confusion, trouble speaking, blurred vision, severe hand trembling (coarse tremor), vision changes (such as growing blind spot, vision loss), joint swelling/pain, pain/discoloration of finger/toes, cold hands/feet.Get medical help right away if you have any very serious side effects, including: severe dizziness, fainting, slow/fast/irregular heartbeat, shortness of breath, seizures.This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.A very serious allergic reaction to this drug is rare.

Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart disease, kidney disease, urinary problems (such as difficulty urinating), underactive thyroid (hypothyroidism), seizures, Parkinson's disease, leukemia, severe dehydration, any infection with high fever, a certain skin disorder (psoriasis).Lithium treatment may rarely reveal an existing condition that affects the heart rhythm (Brugada syndrome). Brugada syndrome is an inherited, life-threatening heart problem that some people may have without knowing it. It can cause a serious (possibly fatal) abnormal heartbeat and other symptoms (such as severe dizziness, fainting, shortness of breath) that need medical attention right away. Brugada syndrome may cause death suddenly. Before starting lithium treatment, tell your doctor if you have any of the following risk factors: Brugada syndrome, unexplained fainting, family history of certain heart problems (Brugada syndrome, sudden unexplained death before 45 years old).This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).If heavy sweating or severe diarrhea occurs, check with your doctor right away how to best continue taking lithium. Take care in hot weather or during activities that cause you to sweat heavily such as during hot baths, saunas, or exercise.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using lithium. Lithium may harm an unborn baby. However, since untreated mental/mood problems (such as bipolar disorder) can harm a pregnant woman and her unborn baby, do not stop taking this medication unless directed by your doctor. Instead, ask your doctor if a different medication would be right for you. If you are planning pregnancy, become pregnant, or think you may be pregnant, talk to your doctor right away about the risks and benefits of this medication.Lithium passes into breast milk and may have undesirable effects on a nursing infant. Breast-feeding is not recommended while using this drug. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Other medications can affect the removal of lithium from your body, which may affect how lithium works. Examples include ACE inhibitors (such as captopril, enalapril), ARBs (such as losartan, valsartan), NSAIDs (such as celecoxib, ibuprofen), "water pills" (diuretics such as hydrochlorothiazide, furosemide), other drugs for mental/mood conditions (such as chlorpromazine, haloperidol, thiothixene), among others. Your doctor may need to adjust your dose of lithium if you are on these medications.The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Some examples are street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (such as SSRIs like fluoxetine/paroxetine, SNRIs like duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.Eat a normal diet with an average amount of sodium.
