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

We found no known interaction between Yucca and Ethambutol 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 Ethambutol states a food rule worth keeping to.

Yucca and Ethambutol

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 Ethambutol and Yucca 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 Yucca at all — not against Ethambutol, 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.

Yucca safety at a glance

Yucca overall Use caution Generally considered low-risk in food amounts, but supplement safety is not well studied.

Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Yucca Itself Has Been Linked To

This is not an interaction — nothing below involves Ethambutol. It is the side-effect record for Yucca on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Yucca, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Hives Worth acting on Additional detail

    “Topically, yucca has been reported to cause phytodermatitis. In one case report, an atopic gardener developed contact urticaria after occupational exposure to weeping fig, spathe flower, and yucca. Allergen skin tests were positive for all three plants.”

  • A stuffy or runny nose Additional detail

    “Environmental exposure to yucca has been associated with allergic rhinitis in 59 patients who exhibited sensitization to yucca after allergen skin testing.”

Everything above comes from the Natural Medicines adverse-effect record for Yucca — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Ethambutol’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Ethambutol column appears here.

How to take them

Some Ethambutol Products Have a Food Rule — Yucca Should Not Break It

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

Absorption is not significantly altered by administration with food.

From the Dosage and Administration section of the FDA label we read for Ethambutol — where that label names a specific product, the instruction is that product's. See the Ethambutol drug page ›

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.

About Yucca

What is Yucca?

  • Joint pain and arthritis
  • Digestive health
  • High cholesterol
  • Inflammation
  • High blood pressure

Yucca is a desert plant traditionally used for joint pain, arthritis, and digestion, and it contains compounds called saponins thought to have anti-inflammatory effects. Human evidence for these uses is very limited, so it should not replace proven treatments. Talk to your pharmacist or doctor before trying it, especially if you are pregnant, breastfeeding, or take other medicines.

Yucca schidigera · Asparagaceae · Root, stem (trunk), and leaves · Capsules, tablets, powder, liquid extract, and tea

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

Yucca: dosing

There is no well-established standard dose for yucca supplements. Doses vary widely between products, and there is not enough research to recommend a specific amount.If you choose to try yucca, follow the directions on the product label and do not exceed them. A pharmacist or doctor can help you decide whether it is appropriate for you and review it against your other medications and health conditions.

About Ethambutol

What Is Ethambutol Used For?

Brand names: Myambutol, Etibi

Ethambutol hydrochloride tablets are used to treat pulmonary tuberculosis — TB that affects the lungs. It must always be taken with at least one other anti-TB medication, never on its own.

For people being treated for TB for the first time, ethambutol is commonly paired with isoniazid, or with isoniazid and streptomycin. For people who have been treated for TB before, it is combined with other second-line anti-TB drugs chosen based on which medicines the bacteria are still sensitive to.
