Which antiemetic is most suitable to recommend for nausea and vomiting in pregnancy?

• A. Promethazine Teoclate
• B. Metoclopramide
• C. Ondansetron
• D. Cyclizine

Answer: (A)

Promethazine works well for nausea and vomiting in pregnancy because it blocks histamine H1 receptors, which reduces the signals from the vestibular system and gut that trigger nausea. Its sedative and anticholinergic effects can help with daytime nausea and associated symptoms, and it has a long history of use in pregnancy with a generally favorable safety/tolerability profile. Compared with some other options, it avoids extrapyramidal side effects (seen with metoclopramide) and potential fetal safety concerns that have been discussed with ondansetron in early pregnancy. Among the available choices, promethazine is a reliable, well-established option for managing nausea and vomiting in pregnancy.
