  • 6/19/2015 - FDA approved perampanel (Fycompa) for the adjunctive treatment of Primary Generalized Tonic-Clonic Seizures (PGTCS) in patients age 12 years and older. 
  • 6/17/2015 - FDA Determines Ezogabine Labeling Adequate to Manage Risks Based on reviews of additional safety reports from patients treated with the anti-seizure drug ezogabine (brand name Potiga), the US Food and Drug Administration has determined that the potential risks of vision loss due to pigment changes in the retina and of skin discoloration can be adequately managed by following the current recommendations in the ezogabine labeling. To further explore any potential long-term consequences of these pigment changes, FDA has required the ezogabine manufacturer, GlaxoSmithKline, to conduct a long-term observational study.  The FDA recommends that health care professionals should continue to follow the recommendations provided in the Boxed Warning, FDA’s most serious type of warning, and the Warnings and Precautions and Indications and Usage sections of the labeling.
  • 6/16/2015 - The FDA has worked with the manufacturer of fosphenytoin (Cerebyx) to update the prescribing information. Studies in patients of Chinese ancestry have found a strong association between the risk of developing SJS/TEN and the presence of HLA-B*1502, an inherited allelic variant of the HLA B gene, in patients using carbamazepine. Limited evidence suggests that HLA-B*1502 may be a risk factor for the development of SJS/TEN in patients of Asian ancestry taking other antiepileptic drugs associated with SJS/TEN, including phenytoin. Consideration should be given to avoiding CEREBYX as an alternative for carbamazepine patients positive for HLAB*1502.

The new prescribing information reads in section 5.8, 'Valproate is associated with dose-related thrombocytopenia ... and  ... decreases in other cell lines and myelodysplasias.  Because of reports of cytopenia, inhibition of secondary phase of platelet aggregation, and abnormal coagulation parameters (e.g., low fibrinogen, coagulation factor deficiencies, acquired VonWillebrand's disease) measurements of complete blood counts and coagulation parameters are recommended before initiating therapy and at periodic intervals.' In addition in section 5.12, the term Multi-organ Hypersensitivity Reaction has been changed to Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) and a completely revised description of DRESS and its severity is provided along with recommendations on how to evaluate it and to stop Depakote." The March 2015 PI is attached here and is also available on the FDA website.
