Watch out for
- Calcium, iron, magnesium, zinc, antacids, and multivitamins bind oral bisphosphonate bone medications (such as alendronate, risedronate, and ibandronate) in the gut and can largely block absorption of a medication that is only minimally absorbed to begin with. Prescribing information has alendronate, immediate-release risedronate and ibandronate taken first thing in the morning with plain water, at least 30-60 minutes before anything else, and delayed-release risedronate (Atelvia) taken right after breakfast, with calcium, antacids, magnesium and iron at another time of day. Either way, the calcium many people are advised to use for bone health fits later in the day. Follow the prescriber's or pharmacist's spacing directions rather than combining doses.
