Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).
Seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include: skin rash, fever, swollen glands, flu-like symptoms, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes. This reaction may occur several weeks after you began using eslicarbazepine.
Eslicarbazepine can reduce the sodium in your body to dangerously low levels, which can cause a life-threatening electrolyte imbalance. Call your doctor right away if you have nausea, lack of energy, confusion, feeling tired or irritable, severe weakness, muscle pain, or increased seizures.
Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, depression, anxiety, or if you feel agitated, hostile, restless, hyperactive (mentally or physically), or have thoughts about suicide or hurting yourself.
Also call your doctor at once if you have:
- severe dizziness or drowsiness, vision changes, thinking problems, trouble with walking or coordination;
- sudden weakness or ill feeling, fever, chills, sore throat, mouth sores; or
- liver problems--nausea, loss of appetite, upper stomach pain, dark urine, jaundice (yellowing of the skin or eyes).
Common side effects may include:
- dizziness, drowsiness, headache;
- feeling tired;
- nausea, vomiting;
- coordination problems, feeling shaky; or
- double vision.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
