Which side effect is specifically associated with dinoprostone use?

Dinoprostone, a prostaglandin E2, is commonly used for cervical ripening and induction of labor. One of the notable side effects specifically associated with the use of dinoprostone is vomiting. This occurs because prostaglandins can stimulate the gastrointestinal tract, leading to increased gastric motility and associated nausea or vomiting.

While hypotension, uterine rupture, and cardiac arrest can occur in various clinical scenarios or with certain medications, they are not directly attributed to dinoprostone. Hypotension is not a common side effect of this medication, and while uterine rupture may happen in the context of labor induction, it is more related to the underlying conditions than directly to dinoprostone use. Cardiac arrest, similarly, is not a noted side effect of dinoprostone but can arise under very specific circumstances unrelated to the drug itself.

Thus, the significance of vomiting as a side effect of dinoprostone highlights its action on the body's prostaglandin pathways, which affects not just labor processes, but also gastrointestinal function.
