Which of the following drugs is considered unsafe for pregnant women?

• A. Antihistamines
• B. ACE inhibitors
• C. Acetaminophen
• D. Beta blockers

Answer: (B)

ACE inhibitors are considered unsafe for pregnant women primarily due to their potential to cause serious harm to the developing fetus. These medications can affect the fetal kidneys, leading to reduced amniotic fluid levels and possible complications with the baby's development. Additionally, there is a significant risk of fetal injury or death if these drugs are taken during the second and third trimesters of pregnancy.

Antihistamines, acetaminophen, and beta blockers are generally considered safer options during pregnancy when necessary, although it's always essential for pregnant women to consult their healthcare provider before taking any medication. It's important to evaluate the risks and benefits of any medication during pregnancy, particularly as it relates to the effects on fetal health and development.
