Lithium Carbonate
Lithobid is a brand-name extended-release formulation of lithium carbonate, a mood stabilizer used primarily to treat bipolar disorder. It helps reduce the frequency and severity of manic episodes and may also prevent depressive episodes. Lithium requires careful blood level monitoring due to its narrow therapeutic window, meaning the difference between a therapeutic dose and a toxic dose is relatively small.

Lithobid is FDA-approved for treatment of manic episodes in bipolar disorder and for maintenance therapy to reduce suicide risk and prevent recurrence of manic and depressive episodes.
The exact mechanism is not fully understood, but lithium is thought to modulate neurotransmitter activity (serotonin, norepinephrine, dopamine) and affect intracellular signaling pathways involved in mood regulation.
Lithium has a narrow therapeutic index requiring regular blood monitoring. Common side effects include tremor, increased thirst/urination, weight gain, and thyroid effects. Dehydration, sodium depletion, and certain medications can increase toxicity risk. Kidney function should be monitored periodically. Do not stop taking without medical supervision.
