Which adverse effect may occur with Aptiom (eslicarbazepine)?

Hyponatremia is a recognized adverse effect of Aptiom (eslicarbazepine). This condition involves lower-than-normal sodium levels in the blood, which can lead to various symptoms such as headache, confusion, seizures, or even coma in severe cases. Aptiom can affect sodium levels partly due to its mechanism of action in stabilizing neuronal membranes and modulating excitatory neurotransmission.

The development of hyponatremia is significant for patients taking this medication and requires monitoring of serum sodium levels, especially during the initiation of therapy or dose adjustments. This makes it vital for healthcare providers to educate patients about the signs and symptoms of hyponatremia, ensuring they seek medical assistance if they experience such issues.

Other options like weight gain, constipation, and hallucinations may be side effects associated with different medications but are not typically linked to Aptiom. Thus, understanding the specific side effects of eslicarbazepine helps in the proper management of patients undergoing treatment with this antiepileptic drug.
