What is the primary medication prescribed for severe vomiting in pregnant women?

The primary medication prescribed for severe vomiting in pregnant women is metoclopramide. This medication is commonly used in the management of nausea and vomiting due to its ability to enhance gastric motility and reduce the sensations of nausea. Metoclopramide works by blocking dopamine receptors in the brain, which helps alleviate symptoms of nausea and vomiting that can be particularly problematic during pregnancy, especially in cases of hyperemesis gravidarum.

While other medications like ondansetron are also used to manage vomiting, metoclopramide is particularly favored in pregnant women due to its established safety profile and effectiveness. Additionally, it can help improve gastric emptying, which is beneficial in addressing severe vomiting scenarios. Understanding the specific context and application of metoclopramide helps delineate its role as a first-line treatment for this concern during pregnancy.
