牛黄解毒片是一种常用的中成药,其功效清热解毒,主治火热内盛,咽喉肿痛,牙龈肿、口舌生疮,目赤肿痛等。近年来,一些人误认为中药无毒副作用,故未经医嘱擅自服用,而常有不良反应发生,谨举数例介绍如下: 1、血小板减少:患者因感冒自服牛黄解毒片,每次自服6片,每日2次,2～3天后出现鼻衄及口腔粘膜溃疡。继续服药后,颜面、上肢、躯干皮肤出现出血点,舌两缘有血疮、牙龈缘有血痂,血小板计数25× Niuhuang Jiedu Tablets is a commonly used proprietary Chinese medicine. Its efficacy is detoxification and clearing. It can be used to treat heat, build up heat, cause sore throat, swollen gums, sores on the tongue, red eyes and so on. In recent years, some people have mistakenly thought that Chinese medicine has no toxic side effects, so they were taken without a doctor’s advice and often had adverse reactions. I would like to give a few examples as follows: 1. Thrombocytopenia: Patients take a self-administered Niuhuang Jiedu Tablet for colds, each time Take 6 tablets, 2 times a day, 2 to 3 days after the occurrence of epistaxis and oral mucosal ulcers. After taking the medicine, there were bleeding spots on the skin of the face, upper limbs, and torso, blood sores on both edges of the tongue, and blood stasis on the gingival margins. The platelet count was 25×.
