What adverse effect is associated with Oxcarbazepine (Trileptal)?

Oxcarbazepine, an anticonvulsant medication, is known to cause hyponatremia as a significant adverse effect. This condition occurs when there is a low concentration of sodium in the blood, which can lead to various neurological symptoms ranging from mild to severe, including confusion, seizures, and even coma in extreme cases. The mechanism behind oxcarbazepine-induced hyponatremia may involve its effects on the sodium channels and its potential to stimulate the release of antidiuretic hormone (ADH), leading to water retention and dilution of sodium levels.

While other options may present potential adverse effects from other medications, they do not commonly associate specifically with oxcarbazepine. Understanding this particular side effect is crucial for monitoring patients who are prescribed oxcarbazepine, making timely intervention possible should hyponatremia develop.
