Drug & supplement interaction

Madder + Hydrochlorothiazide, Lisinopril

Hydrochlorothiazide, Lisinopril brand names: Zestoretic, Prinzide.

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 Madder and Hydrochlorothiazide, Lisinopril 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.

Interaction report

Madder and Hydrochlorothiazide, Lisinopril

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, Lisinopril and Madder 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 Madder at all — not against Hydrochlorothiazide, Lisinopril, 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 Madder and Hydrochlorothiazide, Lisinopril 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.

  • Sweating Additional detail

From our pharmacist’s overview on the Hydrochlorothiazide, Lisinopril page

“I would not add a supplement casually alongside hydrochlorothiazide and lisinopril (Zestoretic, Prinzide). This combination lowers blood pressure with a water pill plus an ACE inhibitor, and most interacting ingredients either drag pressure down too far or push back against the drug, while smaller groups strain the kidneys, drain potas…”

About Madder

What is Madder?

  • Kidney and bladder stones
  • Urinary tract complaints
  • Menstrual problems
  • Natural red dye for fabric
  • Traditional digestive remedy

Madder is a plant whose root has long been used as a red dye and in traditional medicine, mostly for kidney and urinary problems. There is very little reliable human evidence that it works, and some of its compounds have raised concerns about possible cancer-causing effects, so it is generally not recommended for use as a supplement. Talk to your pharmacist or doctor before considering it.

Rubia tinctorum · Rubiaceae · Root · Dried root, powder, capsules, tea, extracts, and natural dye

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

Madder: dosing

There is no established safe or effective dose of madder for any health condition. In general, we do not recommend taking madder root internally. Its safer, well-established use is as a fabric dye rather than as a supplement.

From our Madder monograph — the full record covers uses, side effects and every documented interaction.

About Lisinopril and Hydrochlorothiazide

What Is Lisinopril and Hydrochlorothiazide Used For?

Brand names: Zestoretic, Prinzide

Lisinopril and hydrochlorothiazide tablets — sold as the brand Zestoretic and as the generic combination — are used to treat high blood pressure (hypertension). Lowering blood pressure reduces the risk of serious cardiovascular events such as stroke and heart attack.

This is a fixed-dose combination product and is not intended as a first-line (initial) treatment for high blood pressure. It is typically prescribed for patients whose blood pressure is not adequately controlled on a single medication alone.
