A 35-year-old young male was treated with carbamazepine, oxcarbazepine, levetiracetam, valproate and other antiepileptic drugs for a long time due to secondary epilepsy after viral encephalitis. The epilepsy seizures had not been fully controlled. After about 2 years of treatments, the medication was switched to oral phenobarbital tablets 30 mg thrice daily due to the recurrence of epilepsy. And phenobarbital was discontinued the next year due to well controlled seizures. Four years after drug withdrawal, the patient suffered from coronavirus disease 2019 and the recurrence of epilepsy, and took the original dose of phenobarbital orally again by himself. Three months after medication, the patient had a sudden spontaneous multisegmental thoracic vertebral compression fracture. Vertebral calcium phosphate cement augmentation was performed and phenobarbital was continued. About 2 years after medication, the patient suffered from spontaneous thoracic 12 vertebral compression fracture, with serum 25-hydroxy vitamin D 13.5 μg/L and osteocalcin 8.57 μg/L. Osteoporotic fractures caused by phenobarbital were considered, and the drug was replaced by oral perampanel tablets 2 mg once daily, and vitamin D and calcium were supplemented. At a follow-up of 9 months, the patient′s epilepsy was well controlled, no new fracture events occurred, serum 25-hydroxy vitamin D was 21.6 μg/L, and osteocalcin levels was 10.36 μg/L.
