Summary
Oral iron binds minocycline in the gut and lowers its absorption, and tetracyclines may also reduce iron absorption. This may lead to reduced antibiotic efficacy.
What this interaction means in plain words
Ferric maltol and Minocycline 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.
Ferric maltol belongs to Miscellaneous; Minocycline belongs to Anti Bacterial.
Why it happens
Chelation between minocycline and ferric iron in the gastrointestinal tract reduces absorption of the antibiotic.
