危害:影响各自的疗效,或者药物之间相互作用,产生对身体有毒有害的物质,对身体造成严重的不良反应;可减慢胃排空和胃肠蠕动,使地高辛吸收增加,血药浓度增高,易致中毒。

所以需要谨慎使用,在医生指导下用药。像有些药如中药保和丸、六味地黄丸和西药胃舒平、碳酸氢钠、氢氧化铝、氨茶碱等不能同时服用;中药麦芽、神曲、谷芽与西药抗生素类合用,会使酶的活性降低而丧失药效;中药防风通圣丸、止咳定喘膏、麻杏石甘片与复方降压片,优降宁等合,可抵消降压作用。

贝母与氨茶碱同时使用能引起中毒;中药香连丸、川贝枇杷露与西药阿托品、咖啡因合用会引起中毒;中药朱砂安神丸与西药硫酸亚铁合用易导致汞中毒;中药山楂、五味子等含有机酸,与西药磺胺类药物合用易引起少尿、尿闭或血尿。

总之,在我们的用药过程中,中西药联合治疗越来越多,但我们一定要注意应用的合理 性,才能达到理想的协同作用,从而提高疗效。
中成药与某些西药一起吃,在胃肠道内发生反应,影响西药吸收、降低疗效;有些西药与中成药一起吃,可降低中成药的疗效。
某些中成药与西药一起吃,可产生拮抗作用;中成药与某些西药一起吃可产生毒副作用。

1、中成药与某些西药一起吃,在胃肠道内发生反应,影响西药吸收、降低疗效。
比如含大黄的中成药(牛黄解毒片等),不宜与西药消化酶制剂(胃蛋白酶合剂、胰酶片、多酶片等)同服,因为中成药可吸附或与消化酶结合,影响消化酶的活性。
含鞣酸的中成药(虎杖片、四季清片等)、含明矾的中成药(白金丸等)、含石膏的牛黄解毒片、治胃病的乌败散等,

均不宜与四环素族抗生素、红霉素、利福平、灰黄霉素、制菌霉素同服,因中成药与抗生素发生沉淀,影响抗生素的疗效。
2、有些西药与中成药一起吃,可降低中成药的疗效。比如中药建神曲、保和片等与西药某些抗生素同服,可以降低疗效。
3、某些中成药与西药一起吃,可产生拮抗作用。比如治疗肝阳上亢的密环片、天麻片等不宜与中枢兴奋药同用;

含有麻黄成分的止咳定喘药与痢特灵、优降宁同用可引起血压升高;中药甘草浸膏不宜与双氢克尿噻、洋地黄同用,因可致低血钾,易发生洋地黄中毒。
4、中成药与某些西药一起吃可产生毒副作用。比如各种药酒不可与灭滴灵、痢特灵同用,因易发生乙醇中毒,引起严重的醉酒反应。
含朱砂的中成药磁朱丸、朱砂安神丸等,不宜与三溴合剂同用,因为易生成可溶性汞盐,被吸收后易引起汞中毒。
1.中药麻黄、桂枝等解表发汗药,与扑热息痛、阿司匹林、布洛芬等解热镇痛药合用。
不良反应:发汗过多,引起虚脱;血液粘稠度增加,引起血压升高、心绞痛等。
2.含麻黄的中成药,与洋地黄类强心甙如地高辛、西地兰等合用。
不良反应:麻黄中所含的麻黄碱能加强心肌收缩力,增强强心甙的作用,引发心率失常。
3.含麻黄的中成药,不宜与氨茶碱同用。
不良反应:有协同平喘作用,而毒性增加,可产生头痛、头昏、心率失常等,故合用时宜减少剂量。
4. 蟾酥、罗布麻、夹竹桃等含强心甙成分的中药,与洋地黄类强心甙合用。
不良反应:易引发洋地黄中毒,应避免合用。
一般来说是没有什么危害的,现在都有这个中西结合,所以根本就不会产生什么不良反应,只要遵循医生的指导,然后进行服用就好。
