Oxtellar is used to treat focal (partial) seizures in adults and pediatric patients 6 years of age and older with epilepsy. It may be used as monotherapy or as part of combination therapy with other anti-epileptic drugs.
Oxtellar contains oxcarbazepine, which works by blocking voltage-sensitive sodium channels. This action helps stabilize over-excited neural membranes, preventing the repetitive firing of neurons that contributes to seizure activity.
Oxtellar is typically taken once daily and should be swallowed whole (not crushed or chewed). Common side effects may include dizziness, drowsiness, headache, and double vision. The medication may cause hyponatremia (low blood sodium), so sodium levels may need monitoring during treatment. Do not stop taking this medication suddenly, as this may increase seizure frequency. Inform your healthcare provider of all medications you are taking, as drug interactions can occur.
