Lithium carbonate (lithium carbonate) — Uses, Dosage, Side Effects & Safety

Drug class: Mood stabilizer (antimanic agent)

Overview

Lithium carbonate is a prescription medication used primarily to treat and prevent episodes of mania in people with bipolar disorder. It helps stabilize mood swings, reducing the risk of both manic and depressive episodes. Lithium works by affecting the flow of sodium through nerve and muscle cells in the body, which influences neurotransmitter activity in the brain. This action helps to balance mood and reduce abnormal excitement. Key points for patients: Lithium requires regular blood tests to ensure safe levels, as too much can be toxic. It may take several weeks to notice full effects. Always take lithium exactly as prescribed and do not stop suddenly without consulting your doctor.
