Baclofen is approved by the Food and Drug Administration for spasticity and is also used off-label for trigeminal neuralgia, cluster headache, and substance abuse dependency. Baclofen is 90% renally excreted and has a variable threshold for toxicity in patients with chronic kidney disease. We present a case of accidental overdose of baclofen in a 58-year-old woman with intractable trigeminal neuralgia. She presented with baclofen neurotoxicity symptoms including confusion and tremors and had a morbilliform rash in the dorsum of both hands. This simultaneous presentation is rare and has never been reported. Her symptoms resolved after hemodialysis treatment.
巴氯芬已获美国食品药品监督管理局批准用于治疗痉挛，也被用于治疗三叉神经痛、丛集性头痛和药物滥用依赖等未获批的适应症。巴氯芬90%经肾脏排泄，在慢性肾病患者中其毒性阈值存在个体差异。我们报告一例58岁患有顽固性三叉神经痛的女性意外过量服用巴氯芬的病例。她出现了包括意识模糊和震颤在内的巴氯芬神经毒性症状，双手背部有麻疹样皮疹。这种同时出现的症状很罕见，此前从未有过报道。经血液透析治疗后，她的症状得到缓解。
