Definition/Description

A

針對懷孕婦女妥善設計，且有對照組的研究中，無法證明使用此藥會增高胎兒異常的危險。

Adequate, well-controlled studies in pregnant women have not shown an increased risk of fetal abnormalities.

B

動 物試驗的結果顯示，並無對胎兒有害的證據，但缺乏針對懷孕婦女進行妥善設計且有對照組的研究。(Animal studies have revealed no evidence of harm to the fetus, however, there are no adequate and well-controlled studies in pregnant women.)

或(or)

雖然動物試驗顯示對胚胎有不良作用，但針對懷孕婦女的對照研究中，無法證明對於胎兒的危險性。(Animal studies have shown an adverse effect, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus.)

C

動 物試驗顯示對胚胎有有不良作用，但缺乏針對人類懷孕婦女妥善設計且有對照組的研究。(Animal studies have shown an adverse effect and there are no adequate and well-controlled studies in pregnant women.)

針對動物或人類懷孕婦 女，目前缺乏妥善設計且有對照組的研究，可證明此藥物的危險性。(No animal studies have been conducted and there are no adequate and well-controlled studies in pregnant women.)

D

針對孕婦的控制實驗或觀察研究中，已證實此藥對胎兒有危險性。但在考量利弊得失下，此藥對於治療的利益可能大於潛在的危險性。

Studies, adequate well-controlled or observational, in pregnant women have demonstrated a risk to the fetus. However, the benefits of therapy may outweigh the potential risk.

X

針對動物或孕婦的控制實驗或觀察研究中，已顯示此藥會造成胚胎異常，而且禁用於已經或可能懷孕的婦女。(註：藥物導致的傷害大於可能的利益)
