Oxcarbazepine is used alone or with other medications to treat seizure disorders (epilepsy).
Read the Medication Guide provided by your pharmacist before you start using oxcarbazepine and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with or without food as directed by your doctor, usually twice daily. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Children's dosage is also based on weight. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not stop taking this medication without consulting your doctor. Some conditions (such as seizures) may become worse when this drug is suddenly stopped. Your dose may need to be gradually decreased. Tell your doctor if your seizures worsen.
Dizziness, drowsiness, tiredness, nausea/vomiting, stomach/abdominal pain, headache, trouble sleeping, or constipation may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. A small number of people who take anticonvulsants for any condition (such as seizure, bipolar disorder, pain) may experience depression, suicidal thoughts/attempts, or other mental/mood problems. Tell your doctor right away if you or your family/caregiver notice any unusual/sudden changes in your mood, thoughts, or behavior including signs of depression, suicidal thoughts/attempts, thoughts about harming yourself. Tell your doctor right away if you have any serious side effects, including: loss of coordination, vision changes (such as double vision), rapid/uncontrollable eye movements, shaking (tremor), easy bleeding/bruising, unusual tiredness. Get medical help right away if you have any very serious side effects, including: signs of infection (such as fever, swollen lymph nodes, sore throat that doesn't go away, cough), symptoms of low sodium level (severe nausea, extreme drowsiness, confusion, seizures). Oxcarbazepine may rarely cause very serious (possibly fatal) skin reactions. Some people in certain ethnic groups (including people of Asian/South Asian descent) are at greater risk. Your doctor may order a blood test to measure your risk before you start this medication. If the blood test shows you are at greater risk, your doctor should discuss the risks and benefits of oxcarbazepine and other treatment choices with you. Such skin reactions have developed mostly within the first few months of treatment. Get medical help right away if you develop symptoms of a serious skin reaction such as skin rash/blisters/peeling, itching, or swelling. Ask your doctor or pharmacist for more details. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
