我院34例注射用甲氨蝶呤不良反应报告的回顾性分析

目的：了解注射用甲氨蝶呤不良反应的临床特点，以期为临床安全合理用药提供参考。方法收集2005～2012年我院34例注射用甲氨蝶呤不良反应报告，采用回顾性研究的方法，对其年龄、性别、用药情况、不良反应的类型以及主要临床表现等进行统计与分析。结果34例患者中男24例（70.59%），女10例（29.41%）。年龄8～33岁，其中11～15岁共15例（44.12%）。注射用甲氨蝶呤所致不良反应从用药后10分钟到7日后皆可发生。不良反应累及多个系统-器官，临床表现复杂多样。其中以皮肤及其附件损害最多，其次是消化系统损害、全身性损害、神经系统损害、黏膜损害和生殖系统损害等。结论注射用甲氨蝶呤在大剂量使用时应引起临床高度重视，加强不良反应监测，早期发现给予对症治疗，保障患者用药安全。
