To make sure oxcarbazepine is safe for you, tell your doctor if you have:
depression, or a mood disorder;
a history of suicidal thoughts or actions;
if you are allergic to carbamazepine (Carbatrol, Tegretol).
Some young people have thoughts about suicide when first taking an antidepressant. Your doctor will need to check your progress at regular visits while you are using oxcarbazepine. Your family or other caregivers should also be alert to changes in your mood or symptoms.

If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of oxcarbazepine on the baby.
Oxcarbazepine can make birth control pills less effective. Ask your doctor about using non hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy while taking oxcarbazepine.
Oxcarbazepine can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are taking oxcarbazepine.

How should I take Oxtellar XR (oxcarbazepine)?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Give the liquid directly from the oral syringe, or mix the medicine with a small glass of water. After using the syringe, rinse it with water and allow it to air dry.
You may take the oxcarbazepine oral liquid or regular tablet with or without food.
Take the oxcarbazepine extended-release tablet (Oxtellar XR) on an empty stomach, at least 1 hour before or 2 hours after a meal.
Do not crush, chew, or break an extended-release tablet. Swallow it whole.
Do not stop using oxcarbazepine suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Get your prescription refilled before you run out of medicine completely.
While using oxcarbazepine, you may need frequent blood tests.
Wear a medical alert tag or carry an ID card stating that you take oxcarbazepine. Any medical care provider who treats you should know that you are using oxcarbazepine.
Seizures are often treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice.
Store at room temperature away from moisture and heat. Throw away any unused liquid 7 weeks after opening the bottle.
