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 Rifabutin 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 Rifabutin states a food rule worth keeping to.

Muira Puama and Rifabutin

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 Rifabutin 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 Rifabutin, 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 Rifabutin’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 Rifabutin’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. 3 of them are worth acting on rather than waiting out — marked below.

  • A low white blood cell count Worth acting on mentioned in 4.1% of FDA reports for Rifabutin
  • Chest pain Worth acting on
  • Anemia Worth acting on
  • Bloating or gas
  • Fever mentioned in 5.6% of FDA reports for Rifabutin
  • Reduced appetite
  • Muscle pain
  • Trouble sleeping
  • Stomach upset
  • Stomach pain

Showing the 10 most notable of 16 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 Rifabutin. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,836 voluntary FDA FAERS reports for Rifabutin 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 Rifabutin Products Have a Food Rule — Muira Puama Should Not Break It

At least one FDA label for a product containing Rifabutin says to take it with food. If you take Muira Puama on an empty stomach out of habit, keep them separate — and take Rifabutin 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 Rifabutin 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.

For those patients with propensity to nausea, vomiting, or other gastrointestinal upset, administration of rifabutin at doses of 150 mg twice daily taken with food may be useful.

From the Dosage and Administration section of the FDA label we read for Rifabutin — 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.

From our pharmacist’s overview on the Rifabutin page

“Most people on rifabutin (Mycobutin) are treating or preventing serious mycobacterial infections like MAC or tuberculosis, often for months at a time, and this list deserves a careful read before adding a single capsule. Of the 180 supplements with an interaction on file, three carry a major rating, and all three can shift rifabutin's…”

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 Rifabutin Together: Common Questions

Is it safe to take Muira Puama with Rifabutin?
We do not list a known interaction between Muira Puama and Rifabutin. 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 Rifabutin at the same time of day?
At least one FDA label for a product containing Rifabutin says to take it with food. If you take Muira Puama on an empty stomach out of habit, keep them separate and take Rifabutin with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Rifabutin products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Rifabutin interact with any supplements?
Yes. Rifabutin has documented interactions with 180 supplements in our database — Muira Puama is not one of them. The Rifabutin interaction page linked on this page lists every one, ranked by severity.
