Drug & supplement interaction

Kinetin + Metolazone

Metolazone brand names: Diulo, Zaroxolyn, Mykrox.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Kinetin 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.

Kinetin 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 Kinetin 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.

Kinetin safety at a glance

Kinetin overall Use caution Generally used topically in cosmetics; oral supplement use is not well studied and not recommended.
Pregnancy Avoid There is not enough safety information, so it is best to avoid during pregnancy unless your doctor approves.
Breastfeeding Avoid Safety during breastfeeding has not been established, so caution or avoidance is advised.

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. Kinetin has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (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.

What to actually watch for

No Interaction Found — But Data Suggests Kinetin and Metolazone 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.

  • Itching / A skin rash Additional detail

    Kinetin

    “Orally, the most common adverse effect reported from kinetin is nausea. Headache, diarrhea, tinnitus, flushing, and rash are less common. Topically, kinetin seems to be well tolerated. Erythema, dryness, peeling, burning, stinging, and itching have been reported. However, it is unknown if these symptoms are related to kinetin or other ingredients in the products used.”

About Kinetin

What is Kinetin?

  • Anti-aging skincare
  • Skin smoothing and texture
  • Reducing skin dryness and roughness
  • Evening skin tone
  • Cosmetic moisturizing

Kinetin is a plant growth hormone (a cytokinin) used mainly in topical anti-aging and skincare products, not as an oral dietary supplement. Early laboratory research and small studies suggest it may help skin texture and hydration, but high-quality human evidence is limited. If you want to try it, use it as a cosmetic skin product and check with a pharmacist or dermatologist, especially if you have sensitive skin.

Plant-derived cytokinin (a type of plant hormone); used as a purified compound · Topical creams, serums, lotions, and cosmetic skincare products

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

Kinetin: dosing

There is no established standard dose for kinetin, and it is not meant to be taken as an oral supplement. In cosmetic skincare, it appears as one ingredient among many, usually in low concentrations.The best approach is to follow the directions on the product label for how often to apply it. Do not assume that using more product more often will give better results.

About Metolazone

What Is Metolazone Used For?

Taking Kinetin and Metolazone Together: Common Questions

Is it safe to take Kinetin with Metolazone?
We do not list a known interaction between Kinetin and Metolazone. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Kinetin and Metolazone have any of the same side effects?
Yes — our sources link each of them separately to 5 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Kinetin and Metolazone combination checked?
Interactions in our licensed database are recorded against drug classes. Metolazone is filed under 5 classifications, and Kinetin 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.
Does Kinetin interact with any other medications?
Yes. Kinetin has 122 documented drug interactions in our database — Metolazone is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Metolazone interact with any supplements?
Yes. Metolazone has documented interactions with 222 supplements in our database — Kinetin is not one of them. The Metolazone interaction page linked on this page lists every one, ranked by severity.
