Lithium is a long-term treatment used for episodes of mania and depression.
In this blog article, we will discuss what lithium is used for, how it works to treat bipolar disorder and depression, and common side effects.
What is lithium?
Lithium is an element which gets its name from “lithos” the Greek word for stone, because it is present in trace amounts in almost all rocks.
How does lithium work?
Lithium (Eskalith, Lithobid) is one of the most widely used and studied medications for treating 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 (eg, unusual anger or irritability or a false sense of well-being) to depression or sadness.
Studies show that lithium can significantly reduce suicide risk.
It is not known how lithium works to stabilize a person’s mood. However, it does act on the central nervous system.
It helps one have more control over emotions and helps one cope better with the problems of living.
Lithium is used on a daily basis to reduce the frequency and severity of manic episodes.
What are common side effects of lithium?
Most people who take lithium have no side effects, and it is safe.
However, in less common cases lithium can cause:
· change in heart rhythm
· muscle weakness
· a dazed feeling.
These unwanted side effects often improve with continued use.
With continued use there is evidence of the following occurring and persisting:
· fine tremor
· frequent urination
· weight gain
· swelling from excess fluid.
Lithium can also cause or worsen skin disorders such as acne, psoriasis and rashes. It can also cause problems with the thyroid gland.
The amount of lithium in the body must be carefully controlled and monitored with blood tests.
What is Lithium prescribed for?
Lithium is a long-term treatment for episodes of mania and depression. It’s usually prescribed for at least six months.
The primary condition of people with these symptoms treatable by lithium is bipolar disorder.
The other main target is people with depression who are non-responsive to any other medication.
Bipolar disorder is a brain disorder that causes extreme shifts in mood, energy, and activity levels, and severely interferes with everyday life.
Symptoms of bipolar disorder include both manic and depressive episodes. Up and down, plus and minus.
The following are symptoms of a depressive episode:
· feelings of sadness, emptiness or hopelessness
· very low energy and activity levels
· trouble sleeping (either sleeping too much or too little)
· loss of enjoyment in hobbies or activities
· feelings of worry
· trouble concentrating and trouble remembering things
· changes in appetite (either eating too much or too little)
· feeling sluggish
· thoughts of death or suicide.
Signs of a manic episode are:
· feeling very “up” or elated
· increased energy and activity levels
· feeling jumpy or wired
· trouble sleeping (insomnia)
· talking very fast about a lot of different things
· agitation or irritability
· thoughts racing
· think they can do a lot of things at once
· taking risks such as spending a lot of money or having reckless sex.
If you or someone you know is having thoughts of suicide, seek help immediately.
There are two main types of bipolar disorder: Bipolar I Disorder and Bipolar II Disorder.
Bipolar I Disorder is defined by manic episodes that last at least 7 days, or severe manic symptoms that require immediate hospitalization.
Depressive episodes occur as well and usually last at least 2 weeks. Bipolar I Disorder patients may also have mixed episodes with both manic and depressive symptoms simultaneously.
Bipolar II Disorder is characterized by a pattern of depressive episodes and hypomanic episodes.
Hypomanic episodes have some features of typical manic episodes, but are not severe enough to be considered manic.
Signs of a manic episode are feeling very up or elated.
In addition to people with bipolar disorder, people who are depressed and have not been responding to other treatments may be prescribed lithium.
Lithium can improve mood and decrease suicidal thoughts in these patients.
Major depressive disorder (MDD) is a mood disorder that causes feelings of worthlessness and loss of interest in daily activities.
Common symptoms of MDD are as follows:
· chronic feelings of sadness, tearfulness, emptiness, or hopelessness
· loss of interest in activities that once used to bring enjoyment (e.g. sex, hobbies)
· outbursts of anger and irritability
· issues with sleeping too much or insomnia
· lack of energy and fatigue
· changes in eating patterns and weight (i.e., increased appetite and weight gain or reduced appetite and weight loss)
· slowed speaking, thinking or movement
· feelings of worthlessness
· ruminating on past failures
· feelings of guilt
· trouble concentrating, making proper decisions, and remembering things
· physical problems such as back pain or headaches that cannot be explained by another medical condition.

Lithium: A Doctor, a Drug, and a Breakthrough
From insulin comas and lobotomy to incarceration and exile, Walter Brown chronicles the troubling history of the diagnosis and (often ineffective) treatment of bipolar disorder through the centuries, before the publication of a groundbreaking research paper in 1949.
Cade’s “Lithium Salts in the Treatment of Psychotic Excitement” described, for the first time, lithium’s astonishing efficacy at both treating and preventing the recurrence of manic-depressive episodes, and would eventually transform the lives of patients, pharmaceutical researchers, and practicing physicians worldwide.
And yet, as Brown shows, it would be decades before lithium would overcome widespread stigmatization as a dangerous substance, and the resistance from the pharmaceutical industry, which had little incentive to promote a naturally occurring drug that could not be patented.
