Abstract
BACKGROUND: Peripheral facial nerve palsy is characterized by unilateral facial paresis due to ipsilateral facial nerve dysfunction. Most cases are idiopathic; however, some have specific etiologies, such as herpesvirus infection, immunological disorders, and hypertension. Atomoxetine is a norepinephrine reuptake inhibitor that is used in the treatment of attention deficit hyperactivity disorder (ADHD). This drug is known to cause adverse effects, such as nausea, appetite loss, headache, insomnia, and hypertension.
CASE DESCRIPTION: We herein describe a case of sudden-onset right peripheral facial palsy in a 9-year-old Japanese boy. The patient’s systolic blood pressure was as high as 200 mmHg, and he was therefore admitted to our hospital for investigation. Extensive surveillance including blood examination; endocrinological testing; imaging studies such as computed tomography, magnetic resonance imaging, and renography; and renal biopsy did not reveal any abnormalities. The patient had ADHD and was under treatment with atomoxetine. We discontinued treatment with atomoxetine; the patient showed gradual improvement. His hypertension and facial palsy resolved. We therefore diagnosed the patient with peripheral facial palsy associated with atomoxetine-induced hypertension.
CONCLUSION: Although peripheral facial nerve palsy is usually benign and self-limiting, blood pressure should be monitored in children under treatment with atomoxetine and the possibility of drug-induced hypertension should be considered in order to prevent palsy associated with hypertension.
