What are the Lithium side effects?

Lithium is derived from the Greek word “lithos” which means stone, since it can be found in all rocks in trace amounts. Lithium is an element that is positively charged. When introduced to the body, it may affect the activities inside the cell and on the surface of the cells. It may also interfere with the other positively charged atoms like sodium, potassium, magnesium, and calcium. If the Lithium happens to affect the flow of sodium on the muscle cells and nerve, this might affect the mania or excitation episodes of the person.

Also, Lithium may affect the production and reuptake of neurotransmitters or the chemical messengers in the brain, particularly the tryptophan and serotonin. It can increase the activity of the neurotransmitters in the brain. Lithium can also increase the production of white blood cells in the bone marrow (WBC).

Since 1950s, Lithium has been available for use. But it was in 1970 when U.S. Food and Drug Administration (FDA) approved the use of Lithium carbonate (the most common preparation) as a treatment for several conditions. Lithium is popularly known for its brand names Eskalith and Lithobid.
