Oculogyric crisis after metoclopramide therapy
Summary
A young girl experienced oculogyric crisis after metoclopramide treatment. Diphenhydramine hydrochloride successfully treated the symptoms, highlighting a rare but serious side effect of this medication.
Area of Science:
- Pharmacology
- Ophthalmology
- Neurology
Background:
- Metoclopramide is a commonly prescribed medication for gastrointestinal issues.
- Oculogyric crisis is a rare extrapyramidal side effect characterized by involuntary upward deviation of the eyes.
- Understanding drug-induced adverse events is crucial for patient safety.
Observation:
- A 21-year-old female developed an oculogyric crisis after receiving five oral doses of metoclopramide (10 mg each).
- Symptoms of the oculogyric crisis, including sustained upward eye deviation, manifested shortly after medication intake.
- Intravenous administration of diphenhydramine hydrochloride effectively resolved the oculogyric crisis.
Findings:
- Metoclopramide, despite its common use, can precipitate oculogyric crisis in susceptible individuals.
- The onset of oculogyric crisis can be rapid following metoclopramide administration.
- Diphenhydramine hydrochloride serves as an effective antidote for metoclopramide-induced oculogyric crisis.
Implications:
- Clinicians should be aware of the potential for metoclopramide to cause oculogyric crisis, even with short-term use.
- Prompt recognition and treatment with anticholinergic agents like diphenhydramine are essential for managing this adverse event.
- Further research into the precise mechanisms underlying metoclopramide-induced oculogyric crisis may improve preventative strategies and patient management.
