Drug & supplement interaction

Molybdenum + Prednisone

Prednisone brand names: Deltasone, Cortan, Orasone, Prednisone, Prednicen-M, and others.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Molybdenum 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.

Molybdenum 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 Molybdenum 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Molybdenum at all — not against Prednisone, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

No Interaction Found — But Data Suggests Molybdenum and Prednisone May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 3 of them are worth acting on rather than waiting out — marked below.

    “In one case report of a man in his late thirties, dietary supplementation with molybdenum 300-800 micrograms daily for a cumulative dose of 13.5 mg over 18 days resulted in acute psychosis with visual and auditory hallucinations, petit mal seizures, and a life-threatening grand mal attack, related to frontal cortical damage. Chelation therapy with calcium ethylene diamine tetraacetic acid (CaEDTA) was required.”

Special populations

Molybdenum in Pregnancy & Breastfeeding

Pregnancy Likely Safe

When used orally and appropriately. Molybdenum crosses the placenta by passive diffusion and is exchanged freely between the mother and fetus. However, molybdenum is safe when used in amounts that do not exceed the Tolerable Upper Intake Level (UL) of 1.7 mg/day for women 14 to 18 years, or 2 mg/day for women 19 years of age and older.

Pregnancy Possibly Unsafe

When used orally in high doses. Molybdenum might not be safe during pregnancy when used in doses exceeding the UL of 1.7 mg/day for women 14 to 18 years, or 2 mg/day for women 19 and older.

Lactation Likely Safe

When used orally and appropriately. Molybdenum is safe when used in amounts that do not exceed the Tolerable Upper Intake Level (UL) of 2 mg/day for breast-feeding women 19 years of age or older, or 1.7 mg/day for breast-feeding women ages 14 to 18 years.

Lactation Possibly Unsafe

When used orally in high doses. Molybdenum might not be safe when used in doses exceeding the UL of 2 mg/day for breast-feeding women 19 or older, or 1.7 mg/day for breast-feeding women ages 14 to 18 years.

How to take them

Some Prednisone Products Have a Food Rule — Molybdenum Should Not Break It

At least one FDA label for a product containing Prednisone says to take it with food. If you take Molybdenum 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.

Overlapping uses

What Prednisone Is Prescribed For, and What Molybdenum 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. Molybdenum 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.

Molybdenum has been studied for:

  • Asthma studied, not established Molybdenum has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Molybdenum for asthma

    Although there has been interest in using oral molybdenum for asthma, there is insufficient reliable information about the clinical effects of molybdenum 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 Molybdenum for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

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 Molybdenum

What is Molybdenum?

  • Correcting molybdenum deficiency
  • Supporting enzyme function
  • General nutritional supplementation
  • Sulfite sensitivity (popular claim)

Molybdenum is an essential trace mineral your body needs in tiny amounts to help certain enzymes work. Most people get enough from a normal diet, so supplements are rarely needed unless a doctor identifies a true deficiency. At normal dietary amounts it is considered safe, but high-dose supplements should be used cautiously and under professional guidance.

Tablets, capsules, multivitamin/mineral products, liquid drops

An interaction check asks whether these two react with each other — it does not ask whether Molybdenum is a good idea for someone in your situation. Here is what our Molybdenum record says about it on its own.

Molybdenum: dosing

There is no special "treatment dose" of molybdenum for most people, because deficiency is rare and the body only needs a tiny amount. Health authorities have set recommended daily intakes that are met easily through a normal diet.If you choose to use a supplement, follow the dose on the product label and do not exceed it.

Taking Molybdenum and Prednisone Together: Common Questions

Is it safe to take Molybdenum with Prednisone?
We do not list a known interaction between Molybdenum and Prednisone. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Molybdenum and Prednisone have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Molybdenum and Prednisone at the same time of day?
At least one FDA label for a product containing Prednisone says to take it with food. If you take Molybdenum on an empty stomach out of habit, keep them separate and take Prednisone with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Prednisone products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Molybdenum and Prednisone used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Molybdenum in each. That is a conversation for your prescriber, especially if Prednisone is being adjusted to a target.
Does Prednisone interact with any supplements?
Yes. Prednisone has documented interactions with 208 supplements in our database — Molybdenum is not one of them. The Prednisone interaction page linked on this page lists every one, ranked by severity.
