Lito is used to treat mania that is part of bipolar disorder (manic-depressive illness). It is also used on a daily basis to reduce the frequency and severity of manic episodes. Manic-depressive patients experience severe mood changes, ranging from an excited or manic state (e.g., unusual anger or irritability or a false sense of well-being) to depression or sadness.
It is not known how Lito works to stabilize a person's mood. However, it does act on the central nervous system. It helps you to have more control over your emotions and helps you cope better with the problems of living.
It is important that you and your family understand all the effects of Lito. These effects depend on your individual condition and response and the amount of Lito you use. You also must know when to contact your doctor if there are problems with using the medicine.
Lito is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, Lito is used in certain patients with the following medical conditions:
Neutropenia (a blood condition where there is a decreased number of a certain type of white blood cells).
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.
Adult: Dose depends on the preparation used. Doses should be adjusted to produce a serum-Lito concentration of 0.4-1 mmol/l.

Ask your health care provider any questions you may have about how to use Lito controlled-release and extended-release tablets.
Uses of Lito in details
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.
Use: Labeled Indications
Immediate release: Treatment of manic and mixed episodes and maintenance treatment in patients ≥7 years of age with a diagnosis of bipolar disorder.
Extended release: Treatment of manic episodes and maintenance treatment in patients ≥12 years of age with a diagnosis of bipolar disorder.
Off Label Uses
Bipolar disorder, hypomania
Data from a limited number of patients studied suggest that Lito may be beneficial in the treatment of hypomania.
Lito was used during the 19th century to treat gout. Lito salts such as Lito (Li2CO3), Lito citrate, and Lito orotate are mood stabilizers. They are used in the treatment of bipolar disorder, since unlike most other mood altering drugs, they counteract both mania and depression. Lito can also be used to augment other antidepressant drugs. It is also sometimes prescribed as a preventive treatment for migraine disease and cluster headaches. The active principle in these salts is the Lito ion Li+, which having a smaller diameter, can easily displace K+ and Na+ and even Ca+2, in spite of its greater charge, occupying their sites in several critical neuronal enzymes and neurotransmitter receptors.
Immediate-release capsules are usually given t.i.d. or q.i.d. Doses of controlled-release tablets are usually given b.i.d. (approximately 12-hour intervals). When initiating therapy with immediate-release or controlled-release Lito, dosage must be individualized according to serum levels and clinical response.
When switching a patient from immediate-release capsules to Lito (Lito) CR Controlled-Release Tablets, give the same total daily dose when possible. Most patients on maintenance therapy are stabilized on 900 mg daily, e.g., Lito (Lito) CR 450 mg b.i.d. When the previous dosage of immediate-release Lito is not a multiple of 450 mg, e.g., 1,500 mg, initiate Lito (Lito) CR at the multiple of 450 mg nearest to, but below, the original daily dose, i.e., 1,350 mg. When the 2 doses are unequal, give the larger dose in the evening. In the above example, with a total daily dose of 1,350 mg, generally 450 mg of Lito (Lito) CR should be given in the morning and 900 mg of Lito (Lito) CR in the evening. If desired, the total daily dose of 1,350 mg can be given in 3 equal 450-mg doses of Lito (Lito) CR. These patients should be monitored at 1- to 2-week intervals, and dosage adjusted if necessary, until stable and satisfactory serum levels and clinical state are achieved.
When patients require closer titration than that available with doses of Lito (Lito) CR in increments of 450 mg, immediate-release capsules should be used.
Acute Mania: Optimal patient response to Lito (Lito) can usually be established and maintained with 1,800 mg per day in divided doses. Such doses will normally produce the desired serum Lito level ranging between 1.0 and 1.5 mEq/L.
Dosage must be individualized according to serum levels and clinical response. Regular monitoring of the patient's clinical state and serum Lito levels is necessary. Serum levels should be determined twice per week during the acute phase, and until the serum level and clinical condition of the patient have been stabilized.
Long-Term Control: The desirable serum Lito levels are 0.6 to 1.2 mEq/L. Dosage will vary from one individual to another, but usually 900 mg to 1,200 mg per day in divided doses will maintain this level. Serum Lito levels in uncomplicated cases receiving maintenance therapy during remission should be monitored at least every two months.
Patients unusually sensitive to Lito may exhibit toxic signs at serum levels below 1.0 mEq/L.
N.B.: Blood samples for serum Lito determinations should be drawn immediately prior to the next dose when Lito concentrations are relatively stable (i.e., 8 to 12 hours after the previous dose). Total reliance must not be placed on serum levels alone. Accurate patient evaluation requires both clinical and laboratory analysis.
Elderly patients often respond to reduced dosage, and may exhibit signs of toxicity at serum levels ordinarily tolerated by younger patients.

Caution should be used when Lito and diuretics are used concomitantly because diuretic-induced sodium loss may reduce the renal clearance of Lito and increase serum Lito levels with risk of Lito toxicity. Patients receiving such combined therapy should have serum Lito levels monitored closely and the Lito dosage adjusted if necessary.
Lito levels should be closely monitored when patients initiate or discontinue NSAID use. In some cases, Lito toxicity has resulted from interactions between an NSAID and Lito. Indomethacin and piroxicam have been reported to increase significantly steady-state plasma Lito concentrations. There is also evidence that other nonsteroidal anti-inflammatory agents, including the selective cyclooxygenase-2 (COX-2) inhibitors, have the same effect. In a study conducted in healthy subjects, mean steady-state Lito plasma levels increased approximately 17% in subjects receiving Lito 450 mg b.i.d. with celecoxib 200 mg b.i.d. as compared to subjects receiving Lito alone.
Concurrent use of metronidazole with Lito may provoke Lito toxicity due to reduced renal clearance. Patients receiving such combined therapy should be monitored closely.
There is evidence that angiotensin-converting enzyme inhibitors, such as enalapril and captopril, and angiotension II receptor antagonists, such as losartan, may substantially increase steady-state plasma Lito levels, sometimes resulting in Lito toxicity. When such combinations are used, Lito dosage may need to be decreased, and plasma Lito levels should be measured more often.
Concurrent use of calcium channel blocking agents with Lito may increase the risk of neurotoxicity in the form of ataxia, tremors, nausea, vomiting, diarrhea, and/or tinnitus. Caution is recommended.
The concomitant administration of Lito with selective serotonin reuptake inhibitors should be undertaken with caution as this combination has been reported to result in symptoms such as diarrhea, confusion, tremor, dizziness, and agitation.
The following drugs can lower serum Lito concentrations by increasing urinary Lito excretion: acetazolamide, urea, xanthine preparations, and alkalinizing agents such as sodium bicarbonate.
The following have also been shown to interact with Lito: methyldopa, phenytoin, and carbamazepine.
The likelihood of toxicity increases with increasing serum Lito levels. Serum Lito levels greater than 1.5 mEq/L carry a greater risk than lower levels. However, patients sensitive to Lito may exhibit toxic signs at serum levels below 1.5 mEq/L.
Diarrhea, vomiting, drowsiness, muscular weakness and lack of coordination may be early signs of Lito toxicity, and can occur at Lito levels below 2.0 mEq/L. At higher levels, giddiness, ataxia, blurred vision, tinnitus and a large output of dilute urine may be seen. Serum Lito levels above 3.0 mEq/L may produce a complex clinical picture involving multiple organs and organ systems. Serum Lito levels should not be permitted to exceed 2.0 mEq/L during the acute treatment phase.
Fine hand tremor, polyuria and mild thirst may occur during initial therapy for the acute manic phase, and may persist throughout treatment. Transient and mild nausea and general discomfort may also appear during the first few days of Lito administration.
These side effects are an inconvenience rather than a disabling condition, and usually subside with continued treatment or a temporary reduction or cessation of dosage. If persistent, a cessation of dosage is indicated.
The following adverse reactions have been reported and do not appear to be directly related to serum Lito levels.
Neuromuscular: Tremor, muscle hyperirritability (fasciculations, twitching, clonic movements of whole limbs), ataxia, choreoathetotic movements, hyperactive deep tendon reflexes.
Central Nervous System: Blackout spells, epileptiform seizures, slurred speech, dizziness, vertigo, incontinence of urine or feces, somnolence, psychomotor retardation, restlessness, confusion, stupor, coma, acute dystonia, downbeat nystagmus.
Cardiovascular: Cardiac arrhythmia, hypotension, peripheral circulatory collapse, sinus node dysfunction with severe bradycardia (which may result in syncope).
Neurological: Cases of pseudotumor cerebri (increased intracranial pressure and papilledema) have been reported with Lito use. If undetected, this condition may result in enlargement of the blind spot, constriction of visual fields and eventual blindness due to optic atrophy. Lito should be discontinued, if clinically possible, if this syndrome occurs.
Thyroid Abnormalities: Euthyroid goiter and/or hypothyroidism (including myxedema) accompanied by lower T3 and T4. Iodine 131 uptake may be elevated.. Paradoxically, rare cases of hyperthyroidism have been reported.
EEG Changes: Diffuse slowing, widening of frequency spectrum, potentiation and disorganization of background rhythm.
EKG Changes: Reversible flattening, isoelectricity or inversion of T-waves.
Miscellaneous reactions unrelated to dosage are: Transient electroencephalographic and electrocardiographic changes, leukocytosis, headache, diffuse nontoxic goiter with or without hypothyroidism, transient hyperglycemia, generalized pruritis with or without rash, cutaneous ulcers, albuminuria, worsening of or-ganic brain syndromes, excessive weight gain, edematous swelling of ankles or wrists, and thirst or polyuria, sometimes resembling diabetes insipidus, and metallic taste.
A single report has been received of the development of painful discoloration of fingers and toes and coldness of the extremities within one day of the starting of treatment of Lito. The mechanism through which these symptoms (resembling Raynaud's Syndrome) developed is not known. Recovery followed discontinuance.
Do not use this medication without telling your doctor if you are pregnant. It could cause harm to the unborn baby. Use an effective form of birth control, and tell your doctor if you become pregnant during treatment.
Call your doctor at once if you have any early signs of Lito toxicity, such as nausea, vomiting, diarrhea, drowsiness, muscle weakness, tremor, lack of coordination, blurred vision, or ringing in your ears.
Do not crush, chew, or break an extended-release tablet. Swallow the pill whole.
Drink extra fluids to keep from getting dehydrated while you are taking Lito. Tell your doctor if you have been sweating excessively, or if you are sick with fever, vomiting, or diarrhea.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
Lito can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
