Metoclopramide induced acute dystonic reaction: A case report

Background: Metoclopramide is a commonly used anti-emetic drug known to cause extrapyramidal symptoms as adverse effects, amongst which are dystonic reactions. These reactions are more frequent at high doses of metoclopramide, in female patients, children and adults less than 30 years of age. We hereby present the case of a 16 year old female who had dystonic reactions from metoclopramide, highlighting its unpredictable nature and the shortcomings of the management in resource-limited settings. Case presentation: A 16 year old female Muslim from the Extreme North of Cameroon with no significant past history, was treated for severe malaria and associated refractory vomiting using intravenous quinine and metoclopramide respectively. She developed dystonic reactions after being administered her second dose of metoclopramide. The drug was discontinued and she was administered 8 mg of chlorpheniramine by mouth. Her symptoms resolved after 4 h. She was discharged 2 days later with no further complaints. Conclusions: Metoclopramide causes dystonic reactions which are often unpredictable and is frequently prescribed by health providers. This creates an environment of anxiety for the patient and the caregiver, and can result in life threatening consequences. Patients on metoclopramide should be monitored closely to detect these reactions early, and health facilities should be equipped to cope with the adverse effects before administration. © 2017 The Author(s).
