Healthcare professionals recommend all babies receive a vitamin K injection at birth to help their blood clot effectively. Since 1961, the American Academy of Pediatrics has recommended a single dose of vitamin K injected into the thigh muscle of a newborn infant to prevent bleeding, with the recommended dose based on the infant's weight and given within six hours of birth.

The vitamin K shot helps prevent a serious bleeding condition called vitamin K deficiency bleeding (VKDB). Without it, as many as 1 in 60 babies may develop VKDB. Among babies who receive the shot, that falls to fewer than 1 in 100,000. Giving vitamin K at birth turns a real, measurable risk into a rare one. 來源↗

台灣媽媽社群(BabyMother、Dcard 親子板、BabyHome、mobile01)對新生兒出生 24 小時內肌肉注射維生素 K1 普遍視為「標準程序」少有反對聲音;極少數討論集中於注射部位紅腫疼痛、蠶豆症(G6PD)家長對 K3 的疑慮(K1 仍安全),以及近年國外反疫苗風潮帶起的少數拒打案例引發醫界擔憂。
💬社群實感
資料不足
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為蠶豆症(G6PD)寶寶完全不能打維生素 K(實際只忌 K3,K1 安全)
✓
事實誤以為喝配方奶就完全不需要補維生素 K
✓
事實受國外反疫苗資訊影響,誤信維生素 K 注射會致癌或致自閉
✓
事實誤以為出血疾病罕見,不打也沒差(實際晚發型顱內出血致死率約 13%)
✓
事實誤把維生素 K 注射當成疫苗的一種而選擇一起拒絕
🩹 社群通報的副作用
- 注射部位疼痛、紅腫
- 偶見紅疹、風疹塊
- 極少數過敏反應
- 蠶豆症寶寶若誤用 K3 可能溶血(K1 無此風險)
