Last updated

For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Famotidine raises gastric pH, which can reduce dissolution and absorption of oral non-heme iron salts. Over time this may blunt the response to oral iron therapy.

What this interaction means in plain words

Ibuprofen / famotidine and Iron 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.

Evidence level: Moderate

Why it happens

Reduced gastric acidity decreases solubility and conversion of ferric iron to the absorbable ferrous form.

What to do

Monitor hemoglobin and ferritin response to oral iron. Consider taking iron with vitamin C or at a time away from famotidine, or switch to intravenous iron if the response is poor.

What to ask your pharmacist

  • Should I take them at different times of day?
