Lithium

What is Lithium

Lithium is a mood-stabilising medication used to treat certain mental health conditions. It belongs to a drug class called mood stabilisers.

It is primarily prescribed for:

• Bipolar disorder mania and maintenance treatment
• Prevention of mood swings
• Treatment-resistant depression as add-on therapy
• Schizoaffective disorder in some cases

Lithium does not cure these conditions but helps control mood symptoms over time.

Available formulations and strengths

Lithium is available in several forms:

• Immediate-release tablets
• Extended-release tablets
• Capsules
• Oral liquid solution

Strengths vary by product and country. Treatment is individualised and guided by blood level monitoring.

What is the Recommended Dosage of Lithium

Lithium dosing varies widely and must be determined by a psychiatrist or other licensed mental health specialist.

Dosage depends on:

• The condition being treated
• Age and body weight
• Kidney function
• Other medications
• Blood lithium levels

Dosage forms

Tablets immediate and extended release

• Capsules
• Oral liquid

Lithium requires regular blood tests to maintain safe and effective levels. Exact dosing must follow specialist instructions. Self-adjusting dose is unsafe.

How Lithium Works

Lithium affects chemical signals in the brain that regulate mood, energy, sleep, and behaviour.

It helps:

• Reduce manic episodes
• Stabilise mood swings
• Lower relapse risk
• Improve emotional regulation

The exact mechanism is complex. Lithium influences neurotransmitters, nerve signalling, and cellular processes involved in mood control.

Lithium manages symptoms but typically does not cure bipolar disorder or related conditions. Long-term treatment is often required.
