What effect does antipsychotic medication have related to sodium levels?

Antipsychotic medications can lead to hyponatremia, which is a condition characterized by low sodium levels in the blood. This can occur due to several mechanisms, including the medication's potential influence on the body's fluid balance and its ability to affect hormone levels such as antidiuretic hormone (ADH). When ADH is inappropriately secreted, it can cause the kidneys to reabsorb more water, diluting the sodium levels in the bloodstream and leading to hyponatremia.

Understanding this effect is crucial for healthcare providers as it can lead to serious complications if not recognized and managed appropriately. Monitoring sodium levels in patients on antipsychotic medication can help prevent adverse effects related to this electrolyte imbalance.
