Oxcarbazepine is generally safe for long-term use under medical supervision. Over extended periods, some patients may experience low sodium levels in the blood (hyponatremia), which your doctor can easily monitor with routine blood tests. Long-term use can also sometimes affect bone density, slightly increasing the risk of osteoporosis, or cause minor changes in thyroid function. While these risks sound concerning, they are manageable. Most people tolerate this medication well for years. Regular follow-ups and blood tests with your healthcare provider will ensure you stay safe and healthy. Please do not stop taking your medication without consulting your doctor.
