Vertigoheel induced psychosis: A patient case report.

Objective: To describe a case of a patient who developed psychosis after ingestion of Vertigoheel for treatment of dizziness.

Case summary: A 28-year-old male with no psychiatric history presented with 5 days of worsening depression and psychosis. He denied current use of prescription medications, alcohol, or illicit substances. Approximately 2 weeks prior, while visiting family in Germany, he developed dizziness. A provider in Germany prescribed Vertigoheel, 1 tablet to be taken every hour until symptom improvement. This did not improve his dizziness but did cause him to feel as if he were "in a dream." He stopped taking the medication after 2 days but continued to feel amotivated with decreased appetite and insomnia. Several days later, he developed ego-dystonic auditory hallucinations. He returned to the United States; was admitted to an inpatient psychiatric unit for 4 days; and given olanzapine 5 mg at bedtime, lorazepam 1 mg every evening, and melatonin 6 mg every evening. He experienced gradual improvement in symptoms and was discharged with olanzapine 5 mg daily and outpatient follow-up.

Discussion: Vertigoheel is a homeopathic preparation containing ambra grisea, Cocculus indicus, Conium maculatum, and petroleum. Psychosis was not reported in any of the randomized controlled trials evaluating the use of Vertigoheel for treatment of vertigo. A literature search revealed no published reports of psychosis as a result of administration of any components of Vertigoheel.

Conclusion: A possible causal relationship was observed between the homeopathic supplement Vertigoheel and an acute episode of psychosis in a young male patient with no comorbidities.
