Strontium + Prednisone
Prednisone brand names: Deltasone, Cortan, Orasone, Prednisone, Prednicen-M, and others.
We found no known interaction between Strontium and Prednisone in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Prednisone states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Strontium and Prednisone
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Prednisone and Strontium in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Strontium safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Prednisone
Interactions in our licensed database are recorded against drug classes, not just single drug names. Prednisone is filed under 7 classifications — including corticosteroids, cytochrome p450 2c19 (cyp2c19) inducers, immunosuppressants. Strontium has documented interactions with 5 drug classes — the most serious being androgens (moderate), antacids (moderate) and estrogens (moderate) — and none of Prednisone’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.
Strontium Does Interact With Other Medications
Strontium has 101 moderate known drug interactions in our database — Prednisone isn’t one of them. If you take anything else, check it against the full list below.

Strontium in Pregnancy & Breastfeeding
When consumed orally in food amounts. Strontium has not been linked to toxicity when consumed in dietary amounts, which are typically about 0.5 mg to 1.5 mg/day. ...when strontium chloride is used topically and appropriately as a toothpaste. Strontium chloride hexahydrate (Sensodyne-SC) is an FDA approved product.
When strontium-89 chloride is used during pregnancy or lactation. Strontium-89 chloride is a radioactive isotope which may cause fetal harm. It is FDA pregnancy risk category D; avoid using. Since strontium behaves similarly to calcium in the body, strontium-89 is likely to be excreted into breast milk; avoid using during lactation. There is insufficient reliable information about the safety of oral strontium when used in amounts exceeding typical dietary intake during pregnancy or lactation; avoid using.

No Interaction — But Prednisone May Lower Your Strontium Levels
These two do not interact. The relationship runs the other way: the licensed record lists Prednisone as associated with lower Strontium levels — rated “Insufficient Evidence”.
Theoretically, corticosteroids might reduce strontium levels. Limited data suggest urinary strontium excretion is increased after 5-6 weeks of treatment with high doses of corticosteroids (e.g., hydrocortisone 80-120 mg/day, prednisone 20-30 mg/day, dexamethasone 3mg/day, triamcinolone 12-18 mg/day). The clinical significance of this is unknown.

Some Prednisone Products Have a Food Rule — Strontium Should Not Break It
At least one FDA label for a product containing Prednisone says to take it with food. If you take Strontium on an empty stomach out of habit, keep them separate — and take Prednisone with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Prednisone products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
DOSAGE AND ADMINISTRATION Gastric irritation may be reduced if taken before, during, or immediately after meals or with food or milk.
From the Dosage and Administration section of the FDA label we read for Prednisone — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.
What Prednisone Is Prescribed For, and What Strontium Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Prednisone is a prescription medicine with approved uses on its FDA label. Strontium is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Prednisone is prescribed for: Prednisone treats a broad range of conditions where the body's immune system is overactive or inflammation needs to be controlled. It works across many organ systems, from the lungs and skin to the joints and blood. Doctors prescribe it for conditions like asthma, severe allergies, Crohn's disease, multiple sclerosis flares, certain cancers, and to prevent organ rejection after transplant, among many others.
Strontium has been studied for:
-
Cancer studied, not established Strontium has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Strontium for cancer
Although there has been interest in using oral strontium for metastatic cancer, there is insufficient reliable information about the clinical effects of strontium for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Prednisone on your own; if you are taking Strontium for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.
Questions About Strontium or Prednisone
These are real questions from readers, answered by the pharmacists at HelloPharmacist — written by a person, not generated from a database. Each one covers Strontium or Prednisone, not necessarily both, but if one is close to what you were about to ask it will usually go further than a database entry can:

See Every Supplement That Interacts With Prednisone
This page covers Strontium only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Prednisone page lists 208 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Grapefruit (major), Lily-of-the-valley (major), St. John's Wort (major) and Acacia Rigidula (moderate).
By severity: 4 major · 168 moderate · 36 minor.
From our pharmacist’s overview on the Prednisone page
“Prednisone (Deltasone) suppresses the immune system to control inflammation, and that mechanism shapes most of what can go wrong on this 208-ingredient list, which I read as one to approach carefully rather than casually. Four entries rate major.”

About Strontium
What is Strontium?
- Bone health and osteoporosis
- Reducing fracture risk
- Tooth sensitivity (in some toothpastes)
- Supporting bone density
Strontium is a mineral that has been studied mainly for bone health and osteoporosis. The prescription form (strontium ranelate) showed benefit for fracture risk but carries serious heart-related safety concerns, while the over-the-counter supplement form (strontium citrate) has much less evidence. Talk to your doctor or pharmacist before using it, especially if you have heart disease or are at risk for blood clots.
Mineral element (not a plant) · Capsules and tablets, usually as strontium citrate or strontium ranelate (prescription in some countries)
An interaction check asks whether these two react with each other — it does not ask whether Strontium is a good idea for someone in your situation. Here is what our Strontium record says about it on its own.
Strontium: dosing
There is no firmly established dose for over-the-counter strontium supplements. Strontium and calcium compete for absorption, so they are usually taken at different times of day. Do not assume more is better, since higher amounts may increase risks.
