Abstract
BACKGROUND
Quinacrine is an older antimalarial drug that remains in use for a variety of illnesses including treatment-resistant giardiasis.
CASE PRESENTATION
We report a patient with no prior psychiatric history who developed mild, prodromal psychiatric symptoms when treated with quinacrine for treatment-resistant giardiasis. Symptoms resolved when the drug was stopped, recurred with greater severity (requiring involuntary psychiatric hospitalization) when restarted and promptly resolved again when the drug was finally stopped.
CONCLUSION
Although quinacrine remains in use today, providers may be unaware of its potential for serious neuropsychiatric toxicity.
