Drug & supplement interaction

Lemon Verbena + Metolazone

Metolazone brand names: Diulo, Zaroxolyn, Mykrox.

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 Lemon Verbena and Metolazone 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.

Lemon Verbena and Metolazone

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 Metolazone and Lemon Verbena 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.

Lemon Verbena safety at a glance

Lemon Verbena overall Use caution Generally well tolerated as a tea or food, but concentrated extracts and the essential oil are less studied.
Pregnancy Avoid Not enough safety data, so it is best avoided in medicinal amounts during pregnancy.
Breastfeeding Avoid Safety has not been established, so avoid medicinal amounts while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Metolazone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Metolazone is filed under 5 classifications — including thiazide diuretics, diuretic drugs, antihypertensive drugs. Lemon Verbena has documented interactions with 1 drug class — the most serious being benzodiazepines (moderate) — and none of Metolazone’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.

No Interaction Found — But Data Suggests Lemon Verbena and Metolazone May Share a Side Effect

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.

About Lemon Verbena

What is Lemon Verbena?

Lemon Verbena
  • Digestive upset
  • Anxiety and trouble sleeping
  • Joint pain and inflammation
  • Exercise recovery and oxidative stress
  • Weight management
  • Flavoring and aromatherapy

Lemon verbena is a fragrant South American herb most often enjoyed as a tea or flavoring, and it contains polyphenols like verbascoside that have antioxidant activity in lab studies. Some small studies hint at benefits for inflammation, exercise recovery, and appetite, but the human evidence is limited and far from proven. It is generally well tolerated as a food and tea, but talk with your pharmacist or doctor before using concentrated supplements, and avoid it during pregnancy and breastfeeding.

Aloysia citrodora · Verbenaceae · Leaves and flowering tops; the essential oil is also used · Tea, capsules, liquid extracts, essential oil, and as a flavoring in foods and beverages

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

Lemon Verbena: dosing

There is no official or well-established standardized dose for lemon verbena. As a tea, it is commonly prepared by steeping the dried leaves in hot water, similar to other herbal teas.For capsules and extracts, products vary widely and some are standardized to a certain percentage of polyphenols or verbascoside. More is not always better, and starting with the lowest amount is a sensible approach.

About Metolazone

What Is Metolazone Used For?

Brand names: Diulo, Zaroxolyn, Mykrox

Metolazone tablets are used to treat edema (excess fluid buildup) linked to congestive heart failure or kidney diseases — including nephrotic syndrome and conditions with reduced kidney function. They are also used to treat high blood pressure (hypertension), either alone or alongside other blood pressure medications.

Metolazone tablets may also be used during pregnancy when edema is caused by a medical condition rather than normal pregnancy changes — but routine use in otherwise healthy pregnant women is not appropriate.

Most-Reported Side Effects for Metolazone

From FAERS, the FDA’s public side-effect reporting system (11,176 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 1,247 reports
Acute kidney injury 799 reports
Nausea 761 reports
Renal failure 716 reports
Cardiac failure congestive 683 reports

Do Lemon Verbena and Metolazone have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other.

Interactions in our licensed database are recorded against drug classes. Metolazone is filed under 5 classifications, and Lemon Verbena has documented interactions with 1 drug class — none of Metolazone'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.
