Evidence-Based Treatment Selection for Lithium
Lithium (trade names Eskalith, Lithobid) is a mood stabilizing medication primarily used for the treatment of bipolar disorder. It was one of the first medications approved by the U.S. Food and Drug Administration (FDA) for this indication in 1970. Since then, extensive research has demonstrated lithium’s efficacy in reducing manic episodes associated with bipolar I disorder (American Psychiatric Association, 2013).
The FDA has approved lithium for the acute and long-term treatment of manic episodes associated with bipolar I disorder in adults and children ages 12 and older. It can also be used as maintenance therapy to extend the period of remission and reduce the frequency of additional manic episodes in those with bipolar I disorder (National Institute of Mental Health, 2022). While not FDA-approved for this use, lithium is commonly prescribed off-label for the treatment of bipolar II disorder and recurrent major depressive disorder to reduce the risk of manic or hypomanic episodes (Geddes & Miklowitz, 2013).
Contraindications for lithium use include severe renal impairment, certain cardiac conditions such as sinus node dysfunction, and hyperthyroidism. Due to its narrow therapeutic index, lithium requires careful dosing and monitoring to avoid toxicity. Baseline and ongoing laboratory tests are necessary to monitor lithium levels in the blood as well as kidney and thyroid function (Fountoulakis et al., 2016).
Lithium is believed to work by stabilizing moods. Its exact mechanism of action is not fully understood but it is thought to modulate glutamate and inhibit inositol monophosphatase in the brain, which impacts intracellular signaling pathways (Malhi et al., 2013). Common side effects may include tremor, thirst, frequent urination, and gastrointestinal issues such as nausea, diarrhea, or loss of appetite. More serious but rare side effects can include lithium toxicity, kidney problems, and hypothyroidism with long-term use (NIMH, 2022).
As the primary prescribers and managers of lithium treatment, psychiatric mental health nurse practitioners (PMHNPs) play a key role in its safe and effective use. When initiating lithium, the PMHNP conducts a thorough medical history and physical exam to rule out any contraindications. Baseline laboratory tests are ordered including complete blood count, electrolytes, kidney function, thyroid stimulating hormone, and an electrocardiogram if indicated based on cardiac risk factors (Fountoulakis et al., 2016). The PMHNP educates the patient on lithium’s benefits and risks, the importance of adherence, signs and symptoms of toxicity, and ongoing monitoring needs.
During follow-up visits, the PMHNP assesses the patient’s clinical response and any reported side effects. Adherence is addressed and lithium serum levels are checked, with a target therapeutic range of 0.6-1.2 mEq/L (Geddes & Miklowitz, 2013). Kidney function, electrolytes, and thyroid levels are also monitored periodically based on established clinical guidelines. Dose adjustments are made as needed based on lithium levels and clinical status. The PMHNP provides ongoing support, psychoeducation, and coordination of care to help maximize lithium’s effectiveness and safety over the long term.
In summary, lithium remains a first-line treatment for bipolar I disorder manic episodes and maintenance therapy due to extensive evidence of its efficacy. While requiring careful dosing and monitoring due to its narrow therapeutic index, lithium can provide effective long-term stabilization of moods when managed appropriately by PMHNPs and other prescribers. Four recent scholarly sources that further support lithium’s role in bipolar disorder treatment are discussed below.
