An 81-year-old female with a 50 year history of bipolar disorder and no known history of liver dysfunction LEA RC SERWETMAN PharmD, at time of writing, Clinical Rotation in Acute Care, Advanced Pharmacy Experiential Program, Objective: To report a case of rash and liver dysfunction associated with lamotrigine treatment.Case Summary: An 81-year-old woman with a history of bipolar disorder presented to the emergency department with complaints of fever, chills, nausea, and headache. Two weeks prior to presentation, liver enzymes were normal. Lamotrigine 50 mg/day and sustained-release bupropion 200 mg/day were started after discontinuation of citalopram. The patient had previous exposure to bupropion and documented rash with exposure to penicillin and sulfa. On admission, laboratory tests revealed slightly elevated liver enzymes and slightly low serum albumin. All medications were continued. On hospital day 3, a diffuse maculopapular rash developed on the patient's chest, abdomen, neck, and upper extremities, which was pruritic and warm to the touch. Both lamotrigine and bupropion were discontinued. Liver enzymes increased to more than 3 times the upper limit of normal, and serum albumin decreased. Liver function tests improved on day 6, and the rash resolved. Discussion:Predictive risk factors associated with lamotrigine-induced rash and liver dysfunction include rapid dose titration, previously reported rash with other medications, age, and concurrent interacting medications. More serious adverse effects, such as Stevens-Johnson syndrome and fulminant hepatic failure, have also been associated with lamotrigine treatment. If rash appears at any time during treatment, lamotrigine must be discontinued. According to the Naranjo probability scale, an association between lamotrigine and rash and liver dysfunction could be considered probable in this case. Conclusions:A faster than recommended dose titration may lead to lamotrigine-induced adverse effects such as rash and liver dysfunction in patients with risk factors.
