{"The HLA-B*15:02 allele has been detected in this patient. This allele is associated with high risk of cutaneous adverse drug reaction to phenytoin. DO NOT prescribe phenytoin, fosphenytoin, carbamazepine, or oxcarbazepine. Choose an alternate antiepileptic drug. If the patient has previously used phenytoin consistently for longer than three months without incidence of cutaneous adverse reactions, cautiously consider use of phenytoin in the future. For more information, please consult a clinical pharmacist."}
