Drug & supplement interaction

Kinetin + Hydroxychloroquine

Hydroxychloroquine brand name: Plaquenil.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Kinetin and Hydroxychloroquine 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 label for Hydroxychloroquine states a food rule worth keeping to, and 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 Hydroxychloroquine

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 Hydroxychloroquine 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 Hydroxychloroquine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Hydroxychloroquine is filed under 3 classifications — cytochrome p450 2d6 (cyp2d6) inhibitors, qt interval-prolonging drugs, oral drugs. Kinetin has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Hydroxychloroquine’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 Hydroxychloroquine 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.

How to take them

Some Hydroxychloroquine Products Have a Food Rule — Kinetin Should Not Break It

At least one FDA label for a product containing Hydroxychloroquine says to take it with food. If you take Kinetin on an empty stomach out of habit, keep them separate — and take Hydroxychloroquine with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Hydroxychloroquine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Rheumatoid Arthritis in Adults ( 2.3 ): Initial dosage: 400 mg to 600 mg daily Chronic dosage: 200 mg once daily or 400 mg once daily (or in two divided doses) Systemic Lupus Erythematosus in Adults ( 2.4 ): 200 mg once daily or 400 mg once daily (or in two divided doses) Chronic Discoid Lupus Erythematosus in Adults ( 2.5 ): 200 mg once daily or 400 mg once daily (or in two divided doses) 2.1 Imp

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Hydroxychloroquine page

“Hydroxychloroquine (Plaquenil) can stretch the QT interval on its own, the pause between heartbeats that, prolonged too far, can trigger a dangerous rhythm. Thirteen of the supplements and herbs on this page add to that same effect, grapefruit in large amounts among them, and that overlap is why this list calls for genuine care rather…”

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 Hydroxychloroquine

What Is Hydroxychloroquine Used For?

Brand name: Plaquenil

Hydroxychloroquine tablets are used to treat uncomplicated malaria and to help prevent malaria in areas where the parasite has not developed resistance to it — in both adults and children. It is also used in adults to treat rheumatoid arthritis, systemic lupus erythematosus (SLE), and chronic discoid lupus erythematosus.

There are important limits: it is not recommended for complicated or drug-resistant malaria, malaria acquired in regions where resistance is known, or to prevent malaria relapses caused by P. vivax or P. ovale. Its use for the autoimmune conditions (rheumatoid arthritis and lupus) is approved for adults only.

Taking Kinetin and Hydroxychloroquine Together: Common Questions

Is it safe to take Kinetin with Hydroxychloroquine?
We do not list a known interaction between Kinetin and Hydroxychloroquine. 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 Hydroxychloroquine have any of the same side effects?
Yes — our sources link each of them separately to 6 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.
Should I take Kinetin and Hydroxychloroquine at the same time of day?
At least one FDA label for a product containing Hydroxychloroquine says to take it with food. If you take Kinetin on an empty stomach out of habit, keep them separate and take Hydroxychloroquine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Hydroxychloroquine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Kinetin and Hydroxychloroquine combination checked?
Interactions in our licensed database are recorded against drug classes. Hydroxychloroquine is filed under 3 classifications, and Kinetin has documented interactions with 1 drug class — none of Hydroxychloroquine'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 — Hydroxychloroquine 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 Hydroxychloroquine interact with any supplements?
Yes. Hydroxychloroquine has documented interactions with 32 supplements in our database — Kinetin is not one of them. The Hydroxychloroquine interaction page linked on this page lists every one, ranked by severity.
