What Is Lithium?
Lithium (brand name Lithium) is a alkali metal mood stabilizer (Mood Stabilizer) prescribed for bipolar disorder, treatment-resistant depression, mood disorders, and other psychiatric conditions. Oldest mood stabilizer (approved 1970). ONLY psychiatric medication proven to reduce suicide risk. Neuroprotective (increases brain gray matter). Requires blood level monitoring. Narrow therapeutic index (0.6–1.2 mEq/L). Not metabolized by liver — purely renal elimination.
At Psychiatry Telemed, lithium is prescribed and monitored by board-certified psychiatrists who understand the nuances of Mood Stabilizer pharmacology — selecting the right dose, managing side effects, monitoring drug interactions, and optimizing your treatment through consistent monthly medication management appointments.

How Lithium Affects Neurotransmitters
How Lithium Works
Lithium's mechanism is uniquely complex: it modulates multiple intracellular signaling cascades including inositol phosphate, glycogen synthase kinase-3 (GSK-3), and protein kinase C pathways. It has neuroprotective effects including increased BDNF, gray matter preservation, and anti-inflammatory properties. It is the only psychiatric medication with definitive evidence for reducing suicide risk.

⚠️ FDA Black Box Warning
Lithium toxicity can be life-threatening. Blood levels, renal function, and thyroid function must be monitored regularly. Narrow therapeutic window requires careful dosing.
Drug Interactions
Major Interactions
NSAIDs (increase lithium levels), ACE inhibitors, diuretics (thiazides increase levels), dehydration
CYP Metabolism
No hepatic CYP metabolism. Eliminated entirely by kidneys. Drug interactions are pharmacokinetic (affecting renal excretion) rather than CYP-mediated.
Alcohol
Avoid alcohol during lithium treatment. Both affect the CNS, increasing sedation and impairing judgment.
Generic Versions & Cost
Generic lithium available since Always generic. Approximate cost: $5–15/month. FDA-certified bioequivalent to brand-name Lithium.
