Medically reviewed by · Updated June 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Alchemilla 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.

Alchemilla 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 Alchemilla 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.

How we checked

Why No Interaction Is Listed for Rifabutin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rifabutin is filed under 4 classifications — including cytochrome p450 3a4 (cyp3a4) inducers, antibiotic drugs, cytochrome p450 3a4 (cyp3a4) substrates. Alchemilla has documented interactions with 1 drug class — the most serious being topical drugs (minor) — and none of Rifabutin’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.

What Rifabutin’s Own FDA Label Lists

This is not an interaction — none of it involves Alchemilla. 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. Alchemilla’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Alchemilla side to compare — that is a limit of the record, not a statement that Alchemilla has no side effects.

How to take them

Some Rifabutin Products Have a Food Rule — Alchemilla Should Not Break It

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

What is Alchemilla?

Alchemilla
  • Menstrual and women's health complaints
  • Diarrhea and digestive upset
  • Wound healing (topical)
  • Skin moisturizing (topical)
  • Mild inflammation

Alchemilla (lady's mantle) is a European herb traditionally used for digestive complaints, women's health issues, and as an astringent for skin and wounds. Solid human research is very limited, so its benefits remain largely unproven, and it should be avoided in pregnancy and breastfeeding due to a lack of safety data.

Alchemilla vulgaris · Rosaceae · Above-ground parts (leaves and flowering tops) · Tea, tincture, dried herb, capsules, topical gels and creams

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

Alchemilla: dosing

There is no well-established or standardized dose for Alchemilla, because it has not been studied enough in clinical trials. Traditional use often involves a tea made from the dried herb or a tincture, and topical products are applied to the skin.The best approach is to follow the directions on the product label and not exceed the recommended amount.

About Rifabutin

What Is Rifabutin Used For?

Brand name: Mycobutin

Rifabutin capsules are used to prevent disseminated MAC (Mycobacterium avium complex) disease — a serious bacterial infection that can spread throughout the body — in patients with advanced HIV infection.

It is not approved to treat active tuberculosis (TB), and it must not be used alone in patients who have active TB, as this can lead to antibiotic resistance.

Taking Alchemilla and Rifabutin Together: Common Questions

Is it safe to take Alchemilla with Rifabutin?
We do not list a known interaction between Alchemilla 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 Alchemilla 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 Alchemilla 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.
How was the Alchemilla and Rifabutin combination checked?
Interactions in our licensed database are recorded against drug classes. Rifabutin is filed under 4 classifications, and Alchemilla has documented interactions with 1 drug class — none of Rifabutin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Alchemilla interact with any other medications?
Yes. Alchemilla has 198 documented drug interactions in our database — Rifabutin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Rifabutin interact with any supplements?
Yes. Rifabutin has documented interactions with 180 supplements in our database — Alchemilla is not one of them. The Rifabutin interaction page linked on this page lists every one, ranked by severity.
