Generic Lithium

Introduction

Lithium is a mood‑stabilising medication used primarily for the long‑term management of bipolar disorder in the United Kingdom. The active compound is lithium (usually administered as lithium carbonate or lithium citrate). It belongs to the therapeutic groups commonly associated with mental illness and, in some contexts, antidepressant augmentation. Lithium’s efficacy in preventing manic and depressive episodes has been documented in national guidelines such as the NICE Bipolar Disorder Guideline (CG185). Besides its core indication, clinicians may use lithium off‑label for treatment‑resistant depression or to augment antipsychotic regimens.

What is Lithium?

Lithium is a mono‑ionic salt that, when formulated as tablets or capsules, delivers the active element lithium to the bloodstream. It is classified as a mood stabiliser and is listed under the broader categories of Mental illness treatments. The compound was first introduced in clinical psychiatry in the 197s and has been produced by numerous manufacturers worldwide.

Lithium is the generic version of Lithobid (also known in some markets as Eskalith), containing the same active compound Lithium. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Lithium Works

The precise mechanism of lithium’s therapeutic effect remains incompletely understood, but several biological actions have been identified:

• Intracellular signalling modulation – Lithium inhibits glycogen synthase kinase‑3 (GSK‑3), an enzyme involved in neurotransmitter signalling and neuroplasticity. This inhibition promotes neuronal resilience and stabilises mood‑related pathways.
• Ion transport regulation – Lithium interferes with sodium‑potassium pump activity, influencing neuronal excitability and reducing the likelihood of manic swings.
• Neuroprotective effects – By enhancing brain‑derived neurotrophic factor (BDNF) expression, lithium supports neuronal health and may counteract the neurotoxic impact of stress.

Therapeutically, lithium reaches steady‑state concentrations within 5–7 days after initiation. The drug is cleared renally; a typical adult has a plasma half‑life of 18–24 hours, and it is excreted unchanged in the urine. Maintaining serum levels within the therapeutic window (.6–1.2 mmol/L) is crucial for efficacy while minimising toxicity.

Conditions Treated with Lithium

• Bipolar Disorder (maintenance therapy) – Lithium is the gold‑standard maintenance medication for preventing both manic and depressive relapses. In the UK, it is recommended as first‑line therapy for patients with classic episodic bipolar illness.
• Acute Mania – In hospital settings, lithium may be used alongside antipsychotics to rapidly control manic symptoms, though its onset is slower than some alternatives.
• Treatment‑Resistant Depression (off‑label) – Some clinicians add lithium to antidepressant regimens when standard therapies fail, leveraging its mood‑stabilising properties to augment response.

Epidemiologically, bipolar disorder affects approximately 1–2 % of the UK population, translating to over 600 000 individuals who may benefit from lithium therapy.

Suitable Candidates for Lithium Treatment

• Adult patients (≥18 years) with a confirmed diagnosis of bipolar I or II disorder who require long‑term prophylaxis.
• Individuals with a history of recurrent manic episodes who have responded to lithium in the past or have a family history of lithium responsiveness.
• Patients who can reliably attend regular blood‑monitoring appointments, as lithium therapy necessitates periodic serum level checks and renal function assessments.

Lithium may be less appropriate for:

• People with significant renal impairment (eGFR < 30 mL/min/1.73 m²), as reduced clearance heightens toxicity risk.
• Pregnant or breastfeeding women, where lithium exposure poses potential fetal or neonatal hazards.
• Patients on concomitant medications that markedly increase lithium concentrations (e.g., thiazide diuretics, NSAIDs) unless dose adjustments and monitoring are feasible.

Risks, Side Effects, and Interactions

Common

• Tremor – Fine, postural tremor often appears early in treatment; dose reduction can alleviate it.
• Increased thirst and polyuria – Lithium interferes with renal concentrating ability, leading to higher fluid intake.
• Gastrointestinal discomfort – Nausea, diarrhoea, or abdominal cramps are frequently reported during titration.
• Weight gain – Modest increase in body weight may occur over months of therapy.

Rare

• Hypothyroidism – Approximately 5 % of long‑term users develop reduced thyroid hormone production; routine thyroid testing is advised.
• Diabetes insipidus‑like syndrome – Severe impairment of water reabsorption can cause large volumes of dilute urine.
• Skin rash or alopecia – Uncommon dermatological reactions have been described.

Serious

• Lithium toxicity – Serum levels > 1.5 mmol/L can lead to confusion, seizures, arrhythmias, or coma. Immediate medical attention is required.
• Renal dysfunction – Chronic lithium exposure may induce interstitial nephropathy, culminating in reduced glomerular filtration.
• Neurotoxicity – At high concentrations, lithium can cause cerebellar dysfunction, ataxia, and persistent neurological deficits.

Drug–Drug Interactions

• Thiazide and loop diuretics – Reduce renal lithium clearance, raising serum levels dramatically.
• NSAIDs (e.g., ibuprofen, diclofenac) – May decrease renal excretion of lithium, necessitating dose adjustment.
• ACE inhibitors and ARBs – Can increase lithium concentrations; concurrent use requires close monitoring.
• Other psychotropic agents – Certain antipsychotics (e.g., haloperidol) and antidepressants may potentiate side‑effects but are not contraindicated when managed prudently.

Practical Use: Dosing, Missed Dose, Overdose

• Starting dose – Adults typically begin with 300 mg of lithium carbonate once daily, titrating upward every 5–7 days based on serum levels.
• Maintenance range – Most patients require 600–120 mg daily, divided into two doses to maintain stable plasma concentrations.
• Serum monitoring – Blood is drawn 12 hours post‑dose; therapeutic levels are .6–1.2 mmol/L for maintenance and .8–1. mmol/L for acute mania.

Missed dose: If a dose is forgotten and the next scheduled dose is more than 6 hours away, take the missed tablet. If the next dose is imminent, skip the missed tablet and resume the regular schedule; do not double‑dose.

Overdose: Symptoms may include severe tremor, vomiting, diarrhoea, confusion, and cardiac arrhythmia. Seek emergency medical care immediately. Hemodialysis may be employed in severe cases to expedite lithium clearance.

Practical precautions:

• Maintain consistent fluid intake (≈ 2–3 L/day) and avoid dehydration.
• Limit alcohol, which can exacerbate renal clearance fluctuations.
• Report any new medications, especially over‑the‑counter drugs, to the prescribing clinician.
• Regularly monitor thyroid and kidney function as part of long‑term therapy.

FAQ

• Is Lithium available in both brand‑name and generic forms in the UK?
  Yes, Lithium is marketed under brand names such as Lithobid and Eskalith, as well as generic formulations containing the same active compound. Generic versions are typically less expensive while providing equivalent therapeutic effect.

• Does Lithium require any special storage conditions?
  Lithium tablets should be stored at controlled room temperature, away from direct sunlight, moisture, and extreme heat. Do not refrigerate or freeze the medication, as this may affect tablet integrity.

• What does the packaging of Lithium look like when ordered online?
  Packages generally contain blister‑packed tablets sealed in a tamper‑evident, opaque pouch. The label includes the product name, strength (e.g., 300 mg), batch number, and expiry date, complying with UK labelling standards.

• Can Lithium be safely imported into the UK for personal use?
  Personal import of a three‑month supply of prescription‑only medicines, including lithium, is permitted under the UK Human Medicines Regulations, provided the patient holds a valid prescription and the supplier is a licensed overseas pharmacy.

• Are there any specific warnings for certain ethnic populations?
  Some studies suggest that Asian individuals may have a lower renal clearance of lithium, potentially requiring lower starting doses and closer monitoring of serum levels. Clinicians should consider ethnic variability when prescribing.

• Does the formulation of Lithium differ between regions such as the EU and the US?
  While the active ingredient remains the same, excipients such as binding agents or coatings may vary between EU‑approved and US‑approved products. These differences rarely affect clinical efficacy but may influence tolerability for sensitive patients.

• How does travel affect lithium therapy?
  During long flights or travel across time zones, patients should maintain their dosing schedule based on local time, ensuring consistent plasma concentrations. Adequate hydration is especially important to avoid dehydration‑related lithium level fluctuations.

• What are the historical origins of lithium as a psychiatric medication?
  Lithium was first introduced for psychiatric use by Australian psychiatrist John Cade in 1949, who observed its mood‑stabilising properties in manic patients. Its adoption into modern psychiatry followed extensive clinical trials in the 197s, leading to its inclusion in treatment guidelines worldwide.

• Can lithium affect drug testing, such as workplace urine screens?
  Lithium is not commonly screened for in standard employment drug tests, as it is a therapeutic ion rather than a substance of abuse. However, specialized toxicology panels can detect lithium if specifically requested.

• What are the key differences between lithium carbonate and lithium citrate?
  Both salts deliver the same lithium ion, but lithium carbonate is more widely used due to its higher elemental lithium content per milligram, allowing smaller tablet sizes. Lithium citrate is sometimes preferred for patients with gastrointestinal sensitivity, as it may be gentler on the stomach.
