Summary
Oral magnesium salts can bind oral ibandronate in the gut, reducing its absorption and potentially its efficacy. Oral bisphosphonates are poorly absorbed already, so further reduction matters.
What this interaction means in plain words
Ibandronate and Magnesium sulphate 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.
Ibandronate belongs to Musculoskeletal; Magnesium sulphate belongs to Cardiovascular.
Why it happens
Chelation of ibandronate by divalent magnesium cations in the gastrointestinal tract reduces absorption.
What to do
Give oral ibandronate at least 60 minutes before any oral magnesium-containing product, taken on an empty stomach with plain water. Intravenous ibandronate is not affected.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
