Dolomite and Zoledronic Acid

Here is the interaction we found between these two, with the evidence behind it.

Moderate

BISPHOSPHONATES

Why this applies to Zoledronic Acid

Zoledronic Acid falls under BISPHOSPHONATES — the group Dolomite interacts with.

Theoretically, the calcium and magnesium in dolomite might decrease the absorption of bisphosphonates.
Cations, including calcium and magnesium, can decrease absorption of bisphosphonates. Advise patients to take bisphosphonates at least 30 minutes before dolomite, but preferably at a different time of day.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's some good news if you take zoledronic acid as Reclast or Zometa: it's given as an IV infusion, straight into your vein. The worry on file is that the calcium and magnesium in dolomite can grab onto bisphosphonate pills in your gut and block their absorption. But that whole concern is about swallowed bisphosphonate tablets. Since your zoledronic acid bypasses the stomach entirely, dolomite won't lower how much medicine you get.

That said, two cautions. This interaction note is theoretical and aimed at oral forms, so it doesn't really apply to your infusion. Bigger picture: many health groups discourage dolomite because it can contain lead and other heavy metals. A tested calcium or magnesium product is a safer bet. Please run your supplements by your pharmacist or doctor.

About Dolomite

What is Dolomite?

Dolomite
  • Source of calcium
  • Source of magnesium
  • Bone health support
  • Antacid for heartburn
  • Mineral supplementation

Dolomite is a natural mineral that provides both calcium and magnesium. However, many health authorities advise against using it because dolomite products have been found to contain heavy metals like lead, arsenic, and mercury, and safer, better-tested calcium and magnesium supplements are widely available.

About Zoledronic Acid Injection

What Is Zoledronic Acid Injection Used For?

Brand names: Zometa, Aclasta, Reclast

Zoledronic acid injection is a bisphosphonate given through a vein. The label describes two groups of uses, and not every product is used for every condition.

One group is bone conditions: osteoporosis in postmenopausal women (treatment and prevention), osteoporosis in men, glucocorticoid-induced osteoporosis (bone loss from steroid medicines), and Paget’s disease of bone. The other group is cancer-related: hypercalcemia of malignancy (high blood calcium caused by cancer), multiple myeloma, and bone metastases from solid tumors. Your prescriber chooses the specific product for your condition.
