{"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 fosphenytoin. DO NOT prescribe fosphenytoin, fosfosphenytoin, carbamazepine, or oxcarbazepine. Choose an alternate antiepileptic drug. If the patient has previously used fosphenytoin consistently for longer than three months without incidence of cutaneous adverse reactions, cautiously consider use of fosphenytoin in the future. For more information, please consult a clinical pharmacist."}
