warnings and cautions
5 WARNINGS AND PRECAUTIONS • Suicidal Behavior and Ideation: Monitor for suicidal thoughts or behavior. ( 5.1 ) • Serious Dermatologic Reactions, Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), Anaphylactic Reactions and Angioedema: Monitor and discontinue if another cause cannot be established. ( 5.2 , 5.3 , 5.4 ) • Hyponatremia: Monitor sodium levels in patients at risk or patients experiencing hyponatremia symptoms. ( 5.5 ) • Neurological Adverse Reactions: Monitor for dizziness, disturbance in gait and coordination, somnolence, fatigue, cognitive dysfunction, and visual changes. Use caution when driving or operating machinery. ( 5.6 ) • Withdrawal of eslicarbazepine acetate: Withdraw eslicarbazepine acetate gradually to minimize the risk of increased seizure frequency and status epilepticus. ( 2.6 , 5.7 , 8.1 ) • Drug Induced Liver Injury: Discontinue eslicarbazepine acetate tablets in patients with jaundice or evidence of significant liver injury. ( 5.8 ) • Hematologic Adverse Reactions: Consider discontinuing. ( 5.10 ) 5.1 Suicidal Behavior and Ideation Antiepileptic drugs (AEDs), including eslicarbazepine acetate, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Pooled analyses of 199 placebo-controlled clinical trials (mono-and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% confidence interval [CI]: 1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the estimated incidence of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number of events is too small to allow any conclusion about drug effect on suicide. The increased risk of suicidal thoughts or behavior with AEDs was obser...

6 ADVERSE REACTIONS The following adverse reactions are described in more detail in the Warnings and Precautions section of the label: • Suicidal Behavior and Ideation [see Warnings and Precautions ( 5.1 )] • Serious Dermatologic Reactions [see Warnings and Precautions ( 5.2 )] • Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity [see Warnings and Precautions ( 5.3 )] • Anaphylactic Reactions and Angioedema [see Warnings and Precautions ( 5.4 )] • Hyponatremia [see Warnings and Precautions ( 5.5 )] • Neurological Adverse Reactions [see Warnings and Precautions ( 5.6 )] • Drug Induced Liver Injury [see Warnings and Precautions ( 5.8 )] • Abnormal Thyroid Function Tests [see Warnings and Precautions ( 5.9 )] • Pancytopenia, Agranulocytosis, and Leukopenia [see Warnings and Precautions ( 5.10 )] • Most common adverse reactions in adult patients receiving eslicarbazepine acetate (≥4% and ≥2% greater than placebo): dizziness, somnolence, nausea, headache, diplopia, vomiting, fatigue, vertigo, ataxia, blurred vision, and tremor. ( 6.1 ) • Adverse reactions in pediatric patients are similar to those seen in adult patients. To report SUSPECTED ADVERSE REACTIONS, contact Dr. Reddy’s Laboratories, Inc., at 1-888-375-3784 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult Patients In monotherapy trials in patients with partial-onset seizures [Study 1 and Study 2, see Clinical Studies ( 14.1 ) ], 365 patients received eslicarbazepine acetate, of whom 225 were treated for longer than 12 months and 134 for longer than 24 months. Of the patients in those trials, 95% were between 18 and 65 years old; 48% were male, and 84% were Caucasian. Across controlled and uncontrolled trials in patients receiving adjunctive therapy for partial-onset seizures, 1,195 patients received eslicarbazepine acetate, of whom 586 were treated for longer than 6 months and 462 for longer than 12 months. In the placebo controlled adjunctive therapy trials in patients with partial-onset seizures (Study 3, Study 4 and Study 5), 1,021 patients received eslicarbazepin...
