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 Galphimia Glauca 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

Galphimia Glauca 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 Galphimia Glauca 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 Hydrochlorothiazide, Lisinopril

Interactions in our licensed database are recorded against drug classes, not just single drug names. Hydrochlorothiazide, Lisinopril is filed under 10 classifications — including lisinopril, ace inhibitors (aceis), thiazide diuretics. Galphimia Glauca has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Hydrochlorothiazide, Lisinopril’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 to actually watch for

No Interaction Found — But Data Suggests Galphimia Glauca 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.

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…”
