About Eskalith
Lithium carbonate, marketed here as Generic Eskalith (Lithium carbonate), is a cornerstone medication for the long-term stabilization of mood in adults living with bipolar disorder. By modulating neuronal signaling pathways, it helps to blunt the extremes of mania and depression that characterize this condition. In Singapore, lithium remains a prescription-only option, prescribed after careful assessment of the individual’s clinical history, renal function, and potential drug interactions. While its primary role is mood stabilization, clinicians sometimes consider lithium for other psychiatric or neurological indications, always weighing benefits against the need for laboratory monitoring.
What is Generic Eskalith (Lithium carbonate)?
Generic Eskalith (Lithium carbonate) belongs to the class of mood-stabilizing agents known as lithium salts. First approved by the United States Food and Drug Administration in the early -s, lithium quickly became the prototype treatment for bipolar disorder after numerous randomized trials demonstrated its superiority in preventing both manic and depressive episodes. In Singapore, the Health Sciences Authority classifies lithium carbonate as a prescription-only medicine (POM) and requires regular serum-level monitoring because of its narrow therapeutic window. Although the brand name “Eskalith” is historically associated with Pfizer, the formulation is now widely produced by multiple generic manufacturers, offering patients a cost-effective alternative to proprietary products.
How Generic Eskalith (Lithium carbonate) Works
Lithium’s exact mechanism remains partly elusive, but research converges on several key actions that collectively dampen mood-cycling pathways:
- Second-messenger modulation: Lithium inhibits inositol monophosphatase, reducing the recycling of inositol-1-phosphate and thereby attenuating overactive phosphatidyl-inositol signaling often seen in manic states.
- Neuroprotective signaling: By enhancing the activity of glycogen synthase kinase-3β (GSK-3β) inhibition, lithium promotes neuronal survival, synaptic plasticity, and the expression of brain-derived neurotrophic factor (BDNF). These effects contribute to long-term mood stabilization and may underlie the drug’s prophylactic properties.
- Ion transport regulation: Lithium competes with sodium at neuronal membranes, subtly altering sodium-potassium pump activity and stabilizing neuronal excitability.
Pharmacokinetically, lithium carbonate is absorbed rapidly from the gastrointestinal tract, reaching peak plasma concentrations within 1-3 hours after oral ingestion. It distributes uniformly throughout total body water, crossing the blood-brain barrier in proportion to serum levels. The drug is excreted unchanged by the kidneys, with a half-life of roughly 24 hours in adults with normal renal function. Because renal clearance is the primary elimination route, dosage adjustments are essential in patients with impaired kidney function or those on concurrent nephrotoxic medications.
Why Generic Eskalith (Lithium carbonate) Is Used for Bipolar Disorder
-
Prevention of manic relapse
- Mechanistic link: By dampening inositol-mediated signaling, lithium curtails the hyper-dopaminergic activity that fuels mania.
- Guideline position: The American Psychiatric Association and Singapore’s Clinical Practice Guidelines list lithium as a first-line maintenance therapy for bipolar I disorder.
- Comparison: Compared with atypical antipsychotics, lithium offers a lower risk of metabolic side effects such as weight gain or dyslipidaemia.
-
Reduction of depressive episodes
- Mechanistic link: GSK-3β inhibition and BDNF up-regulation support neurogenesis, which correlates with improved mood regulation during depressive phases.
- Guideline position: Lithium is recommended as a second-line or adjunctive option when antidepressants alone provoke rapid cycling.
- Comparison: Unlike lamotrigine, which primarily addresses depressive polarity, lithium provides broader protection across both poles of the illness.
-
Suicide risk mitigation
- Mechanistic link: Lithium’s neuroprotective actions appear to dampen impulsivity and aggressive tendencies, factors linked to suicidal behaviour.
- Evidence: Meta-analyses of large cohort studies show a ~30 % reduction in suicide mortality among lithium-treated patients versus non-lithium comparators.
- Guideline position: International consensus statements endorse lithium as the preferred agent when suicide risk is a primary concern.
-
Stabilisation of rapid-cycling bipolar disorder
- Mechanistic link: Consistent serum lithium levels suppress the rapid oscillations of neurotransmitter release that characterize rapid cycling.
- Evidence: Controlled trials report a statistically significant decrease in cycle frequency after 12 weeks of lithium therapy.
- Comparison: Valproate may also reduce cycle frequency, but lithium’s evidence base for long-term durability is stronger.
-
Adjunct in treatment-resistant cases
- Mechanistic link: Lithium’s unique modulation of intracellular signaling offers a synergistic effect when combined with antipsychotics or anticonvulsants.
- Evidence: Open-label studies demonstrate improved response rates when lithium is added to clozapine in refractory mania.
Off-Label and Investigational Uses of Generic Eskalith (Lithium carbonate)
- Depression augmentation: Small randomized controlled trials have explored low-dose lithium as an augmenting agent for major depressive disorder, reporting modest improvements in response rates. However, lithium remains unapproved for this indication in Singapore, and clinicians must monitor serum levels closely.
- Cluster headache prophylaxis: A handful of case series suggest lithium may reduce the frequency of cluster headache attacks, likely through its central-pain-modulating pathways. Evidence is limited, and the therapy is considered experimental.
- Neurodegenerative disease research: Preclinical studies indicate lithium may slow tau phosphorylation, a hallmark of Alzheimer’s disease. Human trials have produced mixed results, leaving its role in dementia treatment unsettled.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Generic Eskalith (Lithium carbonate) Right for You?
Lithium is most appropriate for adults with a confirmed diagnosis of bipolar I or II disorder who require long-term relapse prevention. Ideal candidates demonstrate:
- Stable renal function (eGFR ≥ 60 mL/min/1.73 m²).
- No history of thyroid disease untreated, as lithium can exacerbate hypothyroidism.
- Ability to adhere to regular blood-test schedules (typically every 3-6 months).
Special populations warrant extra caution. Pregnant or lactating women are generally advised against lithium due to potential teratogenicity (particularly cardiac malformations in the first trimester). Elderly patients often require lower maintenance doses because of decreased renal clearance. Individuals with severe cardiac rhythm disturbances should discuss alternatives, as lithium can affect sinus node function.
Taking Generic Eskalith (Lithium carbonate) Effectively
- Timing: Take the pill with a full glass of water, preferably after a meal to minimise gastrointestinal upset. Consistent timing (e.g., every morning) helps maintain steady serum concentrations.
- Food and beverage interactions: High-sodium diets blunt lithium absorption, while excessive caffeine can increase renal excretion, leading to sub-therapeutic levels. Encourage a balanced diet with moderate salt intake.
- Missed dose: If a dose is forgotten and it’s less than 12 hours late, take it as soon as remembered. If more than 12 hours have passed, skip the missed dose and resume the regular schedule-do not double-dose.
- Travel considerations: When crossing time zones, adjust the dosing schedule gradually to avoid abrupt shifts in serum lithium. Carry a copy of the prescription and a recent lab report to facilitate local pharmacy verification.
- Hydration: Maintain adequate fluid intake, especially in hot climates like Singapore, to prevent dehydration-induced lithium toxicity.
Understanding Side Effects and How to Manage Them
Lithium’s side-effect profile mirrors its impact on cellular ion transport and neurochemical balance.
- Tremor: Fine, postural tremor arises from altered neuronal excitability. Low-dose beta-blockers (e.g., propranolol) often alleviate this without affecting lithium levels.
- Gastrointestinal discomfort: Nausea and diarrhoea result from direct mucosal irritation. Taking the medication with food, using an extended-release formulation, or dose-splitting can reduce symptoms.
- Thyroid dysfunction: Lithium interferes with thyroid hormone synthesis, leading to hypothyroidism in up to 20 % of long-term users. Baseline TSH testing and periodic monitoring are essential; levothyroxine supplementation is effective if hypothyroidism develops.
- Renal considerations: Chronic use may cause nephrogenic diabetes insipidus, manifesting as polyuria and polydipsia. Reducing sodium intake and ensuring proper hydration can mitigate the effect; dose reduction may be required if renal function declines.
- Weight gain: Mild weight increase may occur via metabolic slowing. Encourage regular exercise and dietary counselling.
- Serious toxicity: At serum levels > 1.5 mmol/L, patients may experience confusion, ataxia, or seizures. Immediate medical attention is warranted if signs of severe toxicity (e.g., vomiting, severe tremor, decreased consciousness) appear.

Frequently Asked Questions
-
How soon will I notice mood-stabilising effects? Lithium’s preventive benefits usually emerge after 2-3 weeks of steady dosing, although full therapeutic levels may take up to 4 weeks. Patience and regular serum monitoring are key.
-
Can I take lithium alongside my antipsychotic medication? Yes, lithium is frequently combined with atypical antipsychotics for enhanced mood control. Nevertheless, both drugs can affect renal function, so joint monitoring of electrolytes and kidney markers is advisable.
-
Is lithium safe for someone with a history of hypertension? Lithium itself does not raise blood pressure, but high sodium intake-often linked to hypertension-can diminish its efficacy. Managing salt consumption supports both blood pressure and lithium stability.
-
What should I do if I develop mild tremor? First, confirm that your serum lithium level remains within the therapeutic range. If it does, a low-dose beta-blocker or adjusting the timing of the dose can help. Always discuss dose changes with your prescriber.
-
Why does my doctor order regular thyroid tests? Lithium can impair thyroid hormone production, potentially leading to hypothyroidism. Routine TSH screening enables early detection and timely treatment with levothyroxine if needed.
-
Can I switch from an immediate-release to an extended-release formulation? Many patients find extended-release tablets improve tolerability by smoothing peak concentrations. Switching should be done under medical supervision to maintain appropriate serum levels.
-
Is lithium compatible with caffeine-heavy diets? Excessive caffeine may increase lithium clearance, possibly lowering its effectiveness. Moderation (no more than 200 mg per day) is recommended to avoid sub-therapeutic concentrations.
-
Will lithium affect my sexual health? Some users report decreased libido or erectile difficulties, likely related to hormonal fluctuations. Discussing these concerns with a healthcare provider can lead to dose adjustments or adjunctive therapies.
-
How is lithium different from newer mood stabilisers like lamotrigine? Lithium uniquely reduces suicide risk and offers robust protection against both manic and depressive episodes. Lamotrigine primarily targets depressive phases and carries a lower risk of renal or thyroid side effects.
-
What emergency signs indicate lithium toxicity? Severe nausea, vomiting, extreme tremor, confusion, or slurred speech should prompt immediate medical evaluation. Prompt treatment can prevent irreversible neurologic damage.
Glossary
- GSK-3β (Glycogen Synthase Kinase-3 Beta): An enzyme that regulates cellular signaling pathways; lithium inhibits this enzyme, contributing to mood-stabilising effects.
- Nephrogenic Diabetes Insipidus: A condition where the kidneys become less responsive to antidiuretic hormone, leading to excessive urination; lithium can induce this on long-term use.
- Therapeutic Window: The narrow range of serum drug concentrations (typically .6-1.2 mmol/L for lithium) where efficacy is achieved without undue toxicity.
