Drug & supplement interaction

Yucca + Hydrochlorothiazide, Losartan Potassium

Hydrochlorothiazide, Losartan Potassium brand name: Hyzaar.

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

We found no known interaction between Yucca and Hydrochlorothiazide, Losartan Potassium 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Yucca and Hydrochlorothiazide, Losartan Potassium

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 Hydrochlorothiazide, Losartan Potassium 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 Hydrochlorothiazide, Losartan Potassium, 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 to actually watch for

No Interaction Found — But Data Suggests Yucca and Hydrochlorothiazide, Losartan Potassium May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

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.
