Calcium carbonate can interact with several medications, affecting absorption or therapeutic effect.

Avoid

• Tetracycline antibiotics (e.g., doxycycline) – reduced absorption.
• Fluoroquinolone antibiotics (e.g., ciprofloxacin) – decreased effectiveness.
• Levothyroxine – impaired uptake leading to suboptimal thyroid control.
• Iron supplements – diminished iron absorption.

Use with caution

• Bisphosphonates – may need separation of dosing times.
• Certain diuretics (e.g., thiazides) – risk of elevated calcium levels.
• Digoxin – possible increase in serum concentration.
• Proton pump inhibitors – may alter calcium balance over long term.
