The bottom line No known interaction

We found no known interaction between Pangamic Acid 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.

Pangamic Acid 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 Pangamic Acid 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 Pangamic Acid 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 Prednisone’s Own FDA Label Lists

This is not an interaction — none of it involves Pangamic Acid. These are the most notable effects listed in the ADVERSE REACTIONS section of Prednisone’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • An electrolyte imbalance Worth acting on
  • Mania or an unusually elevated mood Worth acting on
  • A change in thyroid levels Worth acting on
  • Bone thinning Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Bleeding in the gut Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • A heart attack Worth acting on

Showing the 10 most notable of 55 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Prednisone. Read the label on DailyMed › Where a percentage is shown, it is the share of 491,135 voluntary FDA FAERS reports for Prednisone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Pangamic Acid’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Pangamic Acid side to compare — that is a limit of the record, not a statement that Pangamic Acid has no side effects.

How to take them

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

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

Pangamic Acid has been studied for:

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

    Pangamic Acid for cancer

    Although there has been interest in using oral pangamic acid for cancer, there is insufficient reliable information about the clinical effects of pangamic acid for this purpose.

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

    Pangamic Acid for asthma

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

See Every Supplement That Interacts With Prednisone

This page covers Pangamic Acid 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 Pangamic Acid

What is Pangamic Acid?

  • Claimed athletic performance and endurance
  • General fatigue and energy
  • Heart and circulation support
  • Detoxification claims
  • Antioxidant claims

Pangamic acid, often marketed as 'vitamin B15,' is not a true vitamin and has no established health benefit. Its chemical makeup has never been consistent across products, some versions have raised safety concerns, and it is not approved as a supplement in the United States. We do not recommend using it.

Not a plant part; a synthetic or apricot-kernel-derived chemical compound · Tablets, capsules (often labeled 'B15' or 'vitamin B15')

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

Pangamic Acid: dosing

There is no established or recommended dose for pangamic acid, and no health authority endorses its use. In most cases, the best advice is to choose a different, well-studied option instead.

Taking Pangamic Acid and Prednisone Together: Common Questions

Is it safe to take Pangamic Acid with Prednisone?
We do not list a known interaction between Pangamic Acid 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.
Should I take Pangamic Acid 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 Pangamic Acid 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 Pangamic Acid 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 Pangamic Acid 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 — Pangamic Acid is not one of them. The Prednisone interaction page linked on this page lists every one, ranked by severity.
