Prochlorperazine-induced extrapyramidal effects mimicking meningitis in a child
1Department of Emergency Medicine and Pediatrics, Medical College of Virginia of Virginia Commonwealth University, Richmond 23298-0401, USA.
Abstract:
Certain medications, such as the phenothiazines, may cause side effects that result in neck stiffness and may actually mimic the presentation of meningitis, especially in children. Despite the controversial use of antiemetics, they continue to be used in children with viral gastroenteritis. I describe the case of a child who had a febrile seizure and meningismus during the course of a viral gastroenteritis, not due to meningitis but to the untoward side effect of an antiemetic. Clinicians must be aware that these medications may cause extrapyramidal side effects that may mimic other more serious diseases and lead to unnecessary evaluations; therefore, their use cannot be strongly encouraged. If antiemetics are prescribed, physicians should emphasize possible side effects so that corrective treatment can be initiated promptly.
Insights
Certain antiemetic medications can cause neck stiffness in children, mimicking meningitis. This side effect, particularly with phenothiazines, necessitates careful consideration by clinicians to avoid misdiagnosis and unnecessary evaluations.
Area of Science:
- Pediatric Medicine
- Pharmacology
- Neurology
Background:
- Antiemetics are sometimes used for viral gastroenteritis in children, despite controversial efficacy.
- Phenothiazine medications are known to cause extrapyramidal side effects.
Observation:
- A child presented with febrile seizure and meningismus during viral gastroenteritis.
- The symptoms mimicked meningitis but were attributed to an antiemetic side effect.
Findings:
- Neck stiffness and meningismus can be adverse effects of antiemetic medications.
- These symptoms can be mistaken for serious neurological conditions like meningitis.
Implications:
- Clinicians should be aware of antiemetic-induced extrapyramidal side effects.
- Prompt recognition can prevent misdiagnosis, unnecessary tests, and ensure timely treatment.
- Careful patient counseling regarding potential side effects is crucial.
