Which mood stabilizer can cause nephrotoxicity among its side effects?

Lithium is recognized for its potential to cause nephrotoxicity as a side effect. While it is an effective mood stabilizer used primarily in the treatment of bipolar disorder, its use requires careful monitoring of kidney function. Lithium can lead to renal impairment over time, particularly with long-term use, which is crucial to consider when treating patients.

Patients on lithium therapy should have their renal function monitored regularly to ensure that any potential nephrotoxic effects are identified and managed promptly. Additionally, lithium can cause changes in renal concentrating ability, which can lead to polyuria and thirst, further highlighting the importance of monitoring kidney function in patients receiving this medication.

Other mood stabilizers listed, such as valproic acid, carbamazepine, and lamotrigine, do not have nephrotoxicity as a primary concern in the same way that lithium does, making it essential for practitioners to be vigilant regarding kidney health in patients taking lithium.
