Obsolete but dangerous antacid preparations.

R H Robson, R C Heading

    Postgraduate Medical Journal
    |January 1, 1978
    PubMed
    Summary

    Long-term use of calcium carbonate-sodium bicarbonate powders led to acute hypercalcemia and recurrent kidney stones in patients. These over-the-counter remedies should be regulated to prevent further health issues.

    Area of Science:

    • Nephrology
    • Endocrinology
    • Pharmacology

    Background:

    • Calcium carbonate and sodium bicarbonate powders are widely available over-the-counter medications.
    • Long-term, high-dose consumption of these powders may pose health risks.
    • Patient-practitioner communication regarding medication use is crucial for safety.

    Observation:

    • Three patients developed significant health problems after consuming these powders for over two decades.
    • One patient presented with acute hypercalcemia.
    • Two patients experienced recurrent nephrolithiasis (kidney stones).

    Findings:

    • The study links the prolonged intake of calcium carbonate-sodium bicarbonate powders to severe adverse health outcomes.
    • The unsupervised acquisition of these substances from pharmacists contributed to the cases.
    • The cumulative effect of high calcium and bicarbonate intake is implicated in the observed pathologies.

    Implications:

    • There is a need to re-evaluate the accessibility of over-the-counter calcium carbonate-sodium bicarbonate preparations.
    • Healthcare providers should counsel patients on the potential risks associated with long-term use of such remedies.
    • Increased awareness and regulation may prevent future occurrences of hypercalcemia and nephrolithiasis linked to these powders.
