    Summary

    Quinacrine hydrochloride, used for discoid lupus, can induce psychosis with manic-like symptoms. Close patient monitoring for behavioral changes is crucial to prevent this antimalarial psychosis complication.

    Area of Science:

    • Pharmacology
    • Psychiatry
    • Dermatology

    Background:

    • Quinacrine hydrochloride is prescribed for discoid lupus erythematosus.
    • Drug-induced psychosis is a potential adverse effect of various medications.

    Observation:

    • A patient developed psychosis with manic-like symptoms after two weeks of quinacrine hydrochloride treatment (100 mg twice daily).
    • The observed symptoms mimicked the manic phase of bipolar affective disorder.

    Findings:

    • Quinacrine hydrochloride administration can lead to drug-induced psychosis.
    • Antimalarial psychosis, though potentially rare, is a significant adverse event.

    Implications:

    • Clinicians should closely monitor patients on quinacrine hydrochloride for behavioral changes indicative of psychosis.
    • Early detection of antimalarial psychosis can prevent severe complications of drug therapy.
