特朗普警告：孕妇慎用！知名医药大厂股价暴跌；这种药家中常备，还能吃吗？专家解读

Core Viewpoint - The safety controversy surrounding Tylenol (acetaminophen) has resurfaced, particularly regarding its use by pregnant women and its potential link to autism, following a statement from the U.S. government [2][4]. Group 1: Company Impact - Kenvue, the manufacturer of Tylenol, saw its stock price drop by 7.47% to a historic low following the government's warning [2][4]. - Kenvue maintains confidence in the safety of acetaminophen, asserting that existing scientific evidence does not support a link to autism [2][9]. - The company emphasizes that the FDA has reviewed the safety of acetaminophen during pregnancy multiple times over the past decade and continues to recommend its use [9][10]. Group 2: Scientific Debate - The warning from the Trump administration is based on a review study published in BMC Environmental Health, which suggests prenatal exposure to acetaminophen may interfere with fetal brain development [10][12]. - Contrarily, other studies, including a large-scale analysis from Sweden, found no causal relationship between acetaminophen use during pregnancy and autism or ADHD [13][14]. - Experts argue that the rise in autism diagnoses is partly due to increased awareness and broader definitions of the condition, rather than a direct link to acetaminophen [12][14]. Group 3: Medical Community Response - The American College of Obstetricians and Gynecologists (ACOG) refutes the claim that acetaminophen causes autism, stating that it is the only over-the-counter medication approved for treating fever during pregnancy [14][15]. - Medical professionals warn that untreated fever during pregnancy poses greater risks than the potential effects of acetaminophen [15][16]. - The FDA director has also clarified that there is no definitive causal relationship between acetaminophen and autism, reinforcing its status as the safest over-the-counter option during pregnancy [16].
