Summary
Non-heme oral iron absorption depends on gastric acid, so lansoprazole can reduce iron uptake. With long-term use this may reduce response to iron replacement.
What this interaction means in plain words
Ferrous gluconate and Lansoprazole can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Ferrous gluconate belongs to Miscellaneous; Lansoprazole belongs to Gastrointestinal Tract.
Why it happens
Reduced gastric acid impairs solubilization and reduction of ferric to ferrous iron.
What to do
Monitor hemoglobin and ferritin, and consider a higher iron dose, alternate-day dosing, or IV iron if response is poor.
What to ask your pharmacist
