Clonidine-induced delirium.

Jessica Delaney, Daniel Spevack, Sanjay Doddamani

    International Journal of Cardiology
    |March 21, 2006
    PubMed
    Summary

    Clonidine can cause delirium, a rare but serious side effect. This review highlights the importance of recognizing this adverse drug reaction in patients, especially those with hypertension on multiple medications.

    Area of Science:

    • Neurology
    • Pharmacology
    • Psychiatry

    Background:

    • Clonidine is a commonly prescribed antihypertensive medication.
    • Psychological side effects of clonidine, including delirium, are infrequently reported.
    • Existing literature includes only six reported cases of clonidine-induced delirium.

    Observation:

    • This report details an additional case of clonidine-induced delirium.
    • A comprehensive review of the six previously published cases was conducted.
    • No specific risk factors (e.g., dose, duration, pre-existing mental illness) were clearly identified.

    Findings:

    • Clonidine can precipitate a spectrum of psychological adverse effects.
    • Delirium is a potential, albeit rare, severe psychological outcome of clonidine use.
    • The exact mechanisms and predisposing factors for severe reactions remain unclear.

    Implications:

    • Increased clinical vigilance for delirium is warranted in patients taking clonidine.
    • This is particularly relevant given the prevalence of hypertension and polypharmacy.
    • Early recognition and discontinuation of clonidine are key to managing this adverse event.
