TY - JOUR T1 - Lessons of the month 2: A case of inappropriate drug–drug interaction in kidney transplant JF - Clinical Medicine JO - Clin Med SP - 169 LP - 171 DO - 10.7861/clinmed.2021-0789 VL - 22 IS - 2 AU - Min-Hui Tan AU - Seow-Yeing Yee AU - Rosnawati Yahya Y1 - 2022/03/01 UR - http://www.rcpjournals.org/content/22/2/169.abstract N2 - Carbamazepine remains a first-line antiepileptic medication for the treatment of partial seizures. Despite its widespread use, carbamazepine has significant neurotoxicity and hypersensitivity reactions. We report a case of a patient post-kidney transplant who was on regular carbamazepine for childhood epilepsy and developed nystagmus, diplopia and a broad-base gait after receiving diltiazem. Understanding of the interaction between diltiazem and carbamazepine is necessary to prevent the neurotoxic effects. ER -
