How should I take oxcarbazepine?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

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 let it air dry.

Take the oxcarbazepine extended-release tablet on an empty stomach, at least 1 hour before or 2 hours after a meal.

You may take the oxcarbazepine oral liquid or regular tablet with or without food.

Swallow the extended-release tablet whole and do not crush, chew, or break it.

You may need frequent blood tests.

Do not stop using oxcarbazepine suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.

In case of emergency, wear or carry medical identification to let others know you use 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.
