Unveiling the Unprecedented: An Astonishing Rarity of Metoclopramide Hydrochloride-Triggered Nystagmus in a Pregnant Woman

Metoclopramide hydrochloride is a widely used medication for the treatment of gastrointestinal disorders such as nausea, vomiting, and gastroparesis. However, it has been associated with extrapyramidal side effects (EPS) such as tardive dyskinesia, nystagmus, and other locomotive disorders on rare occasions. These reactions are commonly seen in children and females, particularly in young people. In this article, we report a rare case of a 15-week pregnant woman who was prescribed metoclopramide hydrochloride in view of nausea and vomiting, which was later diagnosed as vomiting in pregnancy not relieved with first-line medications, and has later developed drug-induced nystagmus, highlighting its unpredictable nature and shortcomings of management in the pregnant woman. This article will draw the attention of obstetricians and gynecologists to wisely prescribe metoclopramide hydrochloride for treating nausea and vomiting in pregnant women.
