Obsolete but dangerous antacid preparations

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.
