Lithium Citrate Info

What Is Lithium Citrate?

Lithium citrate is a salt that provides lithium ions, a mood-stabilising element used for many years in psychiatric care. It belongs to the class of lithium salts and works mainly to smooth out mood swings. In Hong Kong, lithium citrate appears in medicines such as Lithium tablets and oral solutions.

Medications That Contain Lithium Citrate

• Lithium tablets - usually supplied in strengths of 300 mg or 450 mg of lithium citrate.
• Lithium oral solution - a liquid formulation often marked as 300 mg per 5 mL, convenient for those who have difficulty swallowing tablets.

These products are available as generic medicines and may also be marketed under local brand names approved by the Hong Kong Department of Health. They can be found in community pharmacies and hospitals, and the packaging is required to display the exact amount of lithium citrate per dose.

What Does Lithium Citrate Treat?

• Bipolar disorder (manic-depressive illness) - helps keep mood from swinging between high (mania) and low (depression) states.
• Acute manic episodes - can calm excessive energy, rapid speech and risky behaviour.
• Maintenance therapy - used after an acute episode to lessen the chance of future mood changes.
• Adjunct for treatment-resistant depression - sometimes added when standard antidepressants are not enough.

Lithium citrate is most often prescribed for adults experiencing these conditions, although use in younger patients follows strict clinical guidelines.

How Lithium Citrate Works

Lithium ions influence the way brain cells communicate, calming excess electrical activity that can trigger manic or depressive episodes. The effect builds over a few days, so patients generally notice a gradual steadiness in mood rather than an immediate change. This stabilising action underpins its use for both acute episodes and long-term maintenance.

Safety Information

Common Side Effects

• Light-headedness or mild dizziness.
• Slight tremor of the hands, usually noticeable only when holding a glass.
• Increased thirst and more frequent urination.
• Mild stomach upset or nausea.

These reactions are usually temporary and often lessen as the body adjusts.

Serious Reactions

• Signs of lithium toxicity such as confusion, severe tremor, slurred speech, vomiting, or a rapid heartbeat.
• Unexplained weakness or fainting.

If any of these appear, urgent medical attention is required.

Who Should Be Cautious

• People with known kidney or thyroid problems should discuss lithium use with a healthcare professional.
• Pregnant or breastfeeding individuals are generally advised to avoid lithium unless a specialist determines it is essential.
• Elderly patients may need lower strengths because the body processes the drug more slowly.
• Individuals with a known allergy to lithium salts should not take lithium citrate.

Interaction Awareness

• Other medicines - diuretics, non-steroidal anti-inflammatory drugs (NSAIDs), and certain antibiotics can raise lithium levels.
• Alcohol - may increase dehydration, which in turn can elevate lithium concentration.
• Food & fluids - maintaining a consistent salt intake helps keep lithium levels stable; sudden changes in diet can affect how the body handles the drug.

What to Know Before Using Lithium Citrate

Store tablets and liquid at room temperature, away from moisture and direct sunlight. Keep all lithium-containing products out of reach of children. Treatment often continues for many months or years, depending on the individual’s condition and response. Because formulations and strengths differ between products, always read the label that comes with your specific medicine. For detailed usage, dosing, administration, refer to your specific medication's information.
