    Meprobamate overdose can cause serious and fatal intoxication, even when taken alone. This anti-anxiety drug poses significant risks, questioning its clinical utility despite its low cost.

    Area of Science:

    • Pharmacology
    • Clinical Toxicology
    • Drug Safety

    Background:

    • Meprobamate is an anti-anxiety medication.
    • Drug overdosage presents a significant public health concern.
    • Understanding the toxicity profile of commonly used medications is crucial for patient safety.

    Purpose of the Study:

    • To investigate the incidence and severity of meprobamate overdosage admissions.
    • To characterize the clinical outcomes of patients admitted for meprobamate intoxication.
    • To evaluate the risks associated with meprobamate use in overdose scenarios.

    Main Methods:

    • Retrospective analysis of hospital admission data.
    • Inclusion criteria: patients admitted for psychotropic drug overdosage.
    • Data collected on meprobamate involvement, dosage, and clinical manifestations.

    Main Results:

    • Meprobamate was involved in 6.5% of 773 psychotropic drug overdosage admissions.
    • Ingested doses reached up to 40 gm, with severe outcomes including deep coma (25 cases), hypotension (23 cases), and need for ventilation (16 cases).
    • Two fatalities occurred, one potentially from meprobamate alone (12-20 gm).

    Conclusions:

    • Meprobamate overdosage frequently leads to severe and potentially fatal intoxication, even as a single agent.
    • The drug's questionable efficacy and risk of life-threatening toxicity are significant drawbacks.
    • Clinical use of meprobamate should be carefully considered due to its overdose risks.
