What is the guideline for benzodiazepine prescribing for dental anxiety in pregnancy risk?

• A. Avoid unless clearly indicated; consult physician.
• B. Prescribe routinely.
• C. Always use in all trimesters.
• D. Never use.

Answer: (A)

In this scenario, the guiding idea is to minimize fetal exposure to medications with potential risks during pregnancy and to involve the patient’s physician when a benzodiazepine might be considered. Benzodiazepines cross the placenta and can affect the fetus, potentially causing neonatal sedation, respiratory depression at birth, hypotonia, and withdrawal after delivery; there is also concern about teratogenic risk, especially with early exposure. For dental anxiety, this means they should be avoided unless there is a clear, justified indication and a physician’s assessment supports use. The preference is to rely on nonpharmacologic anxiety management and safer alternatives first, and to coordinate with obstetric care if a sedative is deemed necessary for the mother's safety or procedure success.

The other options are too absolute or inappropriate for routine practice. Prescribing benzodiazepines routinely would unnecessarily expose the fetus. Using them in all trimesters is unsafe given the fetal risks. Saying they should never be used oversimplifies the situation, as there may be rare, clearly indicated cases where a physician approves use after careful risk–benefit discussion.
