No Known Interaction
Medically reviewed by · Updated June 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Muira Puama 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.

Muira Puama 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 Muira Puama 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 Muira Puama 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 Muira Puama. 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. Muira Puama’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Muira Puama side to compare — that is a limit of the record, not a statement that Muira Puama has no side effects.

How to take them

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

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

Everything else you take

See Every Supplement That Interacts With Prednisone

This page covers Muira Puama 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 Muira Puama

What is Muira Puama?

  • Low libido
  • Erectile difficulty
  • Sexual performance
  • Fatigue and low energy
  • General tonic for stress

Muira puama is a Brazilian plant traditionally used as an aphrodisiac and general tonic, often nicknamed 'potency wood.' Human research is very limited, so its benefits are not well proven, and there is little information on its long-term safety. Talk with your pharmacist or doctor before trying it, especially if you have a health condition or take other medicines.

Ptychopetalum olacoides · Olacaceae · Roots and bark (sometimes wood) · Capsules, tinctures, liquid extracts, teas, and powders

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

Muira Puama: dosing

There is no well-established or standardized dose for muira puama. Products differ in form (capsule, tincture, tea) and in how concentrated they are, so amounts on labels vary widely.The safest approach is to follow the directions on the specific product you buy and to start low.

Taking Muira Puama and Prednisone Together: Common Questions

Is it safe to take Muira Puama with Prednisone?
We do not list a known interaction between Muira Puama 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 Muira Puama 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 Muira Puama 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.
Does Prednisone interact with any supplements?
Yes. Prednisone has documented interactions with 208 supplements in our database — Muira Puama is not one of them. The Prednisone interaction page linked on this page lists every one, ranked by severity.
