There was an increased risk of visual changes and dizziness and coordination abnormalities during the titration period, in patients >60 years of age, and with concomitant carbamazepine use; consider dosage modifications in patients using eslicarbazepine and carbamazepine concomitantly. Caution patients about performing tasks which require mental alertness (eg, operating machinery or driving). Dermatologic reactions: Potentially serious, sometimes fatal, dermatologic reactions including Stevens-Johnson syndrome (SJS) have been reported; monitor for signs and symptoms of skin reactions; discontinuation and conversion to alternate therapy may be required. Avoid use in patients with prior dermatologic reaction with either oxcarbazepine or eslicarbazepine. Hematologic effects: Cases of pancytopenia, agranulocytosis, and leukopenia have been reported; consider discontinuing eslicarbazepine if these hematologic abnormalities develop. Hepatic effects: Hepatic effects ranging from mild to moderate elevations in transaminases (>3 times the upper limit of normal) to rare cases of concomitant elevations of total bilirubin (>2 times the upper limit of normal) have been reported. Perform baseline liver laboratory tests. Discontinue in patients with jaundice or other evidence of significant liver injury. Hypersensitivity reactions: Rare cases of anaphylaxis and angioedema have been reported. Permanently discontinue should symptoms occur. Avoid use in patients with a prior anaphylactic-type reaction with either oxcarbazepine or eslicarbazepine. Hyponatremia: Clinically significant hyponatremia (serum sodium <125 mmol/L) and concurrent hypochloremia may develop during use. In controlled trials, effects were dose-related, appeared within the first 8 weeks of treatment (as early as after 3 days), and resolved without additional treatment after eslicarbazepine was discontinued. Consider monitoring serum sodium and chloride levels during maintenance treatment, especially in patients at risk for hyponatremia and if symptoms of hyponatremia develop. Depending on the severity of hyponatremia, the dose of eslicarbazepine may need to be reduced or discontinued. Multiorgan hypersensitivity reactions: Potentially serious, sometimes fatal drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan hypersensitivity reactions, have been reported. Monitor for signs and symptoms (eg, fever, rash, lymphadenopathy, eosinophilia) in association with other organ system involvement (eg, hepatitis, nephritis, hematological abnormalities, myocarditis, myositis). Evaluate immediately if signs or symptoms are present. Discontinuation and conversion to alternate therapy may be required. Avoid use in patients with a prior DRESS reaction with either oxcarbazepine or eslicarbazepine. Suicidal ideation: Pooled analysis of trials involving various antiepileptics (regardless of indication) showed an increased risk of suicidal thoughts/behavior (incidence rate: 0.43% treated patients compared to 0.24% of patients receiving placebo); risk observed as early as 1 week after initiation and continued through duration of trials (most trials 24 weeks). Monitor all patients for notable changes in behavior that might indicate suicidal thoughts or depression; patients should be instructed to notify healthcare provider immediately if symptoms occur. Thyroid function: Dose-dependent decreases in serum T 3 and T 4 (free and total) values have been observed; changes were not associated with other abnormal thyroid function tests suggesting hypothyroidism. Disease-related concerns: Renal impairment: Clearance is decreased in patients with impaired renal function; dosage adjustment is necessary in patients with CrCl> <50 mL/minute. Hepatic impairment: Avoid use in patients with severe hepatic impairment. Concurrent drug therapy issues: Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information. Other warnings/precautions: Withdrawal: Anticonvulsants should not be discontinued abruptly because of the possibility of increasing seizure frequency; therapy should be withdrawn gradually to minimize the potential of increased seizure frequency, unless safety concerns require a more rapid withdrawal. Monitoring Parameters Seizure frequency; liver enzymes (baseline); serum sodium and chloride as deemed necessary during maintenance treatment, particularly in patients receiving other medications known to decrease sodium levels or if symptoms of hyponatremia develop; symptoms of CNS depression (dizziness, disturbance in gait and coordination, somnolence); visual changes; hypersensitivity reactions. Monitor for suicidality (eg, suicidal thoughts, depression, behavioral changes). For adjunctive therapy, serum levels of concomitant antiepileptic drugs during titration as necessary. Pregnancy Risk Factor DELETE Pregnancy Considerations Adverse events have been observed in animal reproduction studies. Eslicarbazepine may decrease plasma concentrations of hormonal contraceptives; additional or alternative nonhormonal contraceptives are recommended in women of reproductive potential. Patients exposed to eslicarbazepine during pregnancy are encouraged to enroll themselves into the AED Pregnancy Registry by calling 1-888-233-2334. Additional information is available at http://www.aedpregnancyregistry.org . Patient Education Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?) Patient may experience headache, nausea, vomiting, fatigue, or tremors. Have patient report immediately to prescriber signs of infection, signs of depression (suicidal ideation, anxiety, emotional instability, or confusion), signs of low sodium (headache, difficulty focusing, memory impairment, confusion, weakness, seizures, or change in balance), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), swollen glands, shortness of breath, excessive weight gain, swelling of arms or legs, angina, severe dizziness, passing out, severe muscle pain, severe muscle weakness, severe loss of strength and energy, vision changes, seizures, bruising, bleeding, chills, involuntary eye movements, difficulty walking, agitation, irritability, panic attacks, mood changes, or signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes) (HCAHPS). Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions. Intended Use and Disclaimer: Should not be printed and given to patients.
