Arum + Lonafarnib
Lonafarnib brand name: Zokinvy.
We found no known interaction between Arum and Lonafarnib 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 Lonafarnib 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.
Arum and Lonafarnib
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 Lonafarnib and Arum 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.
Arum safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Lonafarnib
Interactions in our licensed database are recorded against drug classes, not just single drug names. Lonafarnib is filed under 5 classifications — including cytochrome p450 2c9 (cyp2c9) substrates, cytochrome p450 3a4 (cyp3a4) inhibitors, nephrotoxic drugs. Arum has documented interactions with 1 drug class — the most serious being iron (minor) — and none of Lonafarnib’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.
Arum Does Interact With Other Medications
Arum has 1 minor known drug interaction in our database — Lonafarnib isn’t one of them. If you take anything else, check it against the full list below.

Some Lonafarnib Products Have a Food Rule — Arum Should Not Break It
At least one FDA label for a product containing Lonafarnib says to take it with food. If you take Arum on an empty stomach out of habit, keep them separate — and take Lonafarnib 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 Lonafarnib 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.
If a dose is missed, take the dose as soon as possible with food, up to 8 hours prior to the next scheduled dose.
From the Dosage and Administration section of the FDA label we read for Lonafarnib — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
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.
See Every Supplement That Interacts With Lonafarnib
This page covers Arum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lonafarnib page lists 160 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Asarabacca (major), Grapefruit (major), Siberian Cocklebur (major) and St. John's Wort (major).
By severity: 5 major · 115 moderate · 40 minor.
From our pharmacist’s overview on the Lonafarnib page
“If you or your child takes lonafarnib (Zokinvy) for progeria, treat supplements with real caution. Most of the 160 flagged ingredients cross paths with the CYP3A4 enzyme, the same one that handles lonafarnib, so the traffic runs both ways.”

About Arum
What is Arum?
- Coughs and chest congestion
- Sore throat
- Promoting sweating (diaphoretic)
- Skin and wart remedies (topical folk use)
- Digestive complaints
Arum is a traditional European plant whose root has been used in folk medicine, but there is essentially no reliable human research to support any health benefit. The raw plant is toxic and irritating because of calcium oxalate crystals, so it should not be eaten or used casually. We do not recommend using Arum as a supplement, especially during pregnancy or breastfeeding.
Arum maculatum · Araceae · Root (tuber), and sometimes leaves · Dried root preparations, tinctures, and traditional folk remedies
An interaction check asks whether these two react with each other — it does not ask whether Arum is a good idea for someone in your situation. Here is what our Arum record says about it on its own.
Arum: dosing
There is no established or standardized safe dose for Arum. Because the plant is toxic and human research is lacking, no trustworthy dosing guidelines exist.We do not recommend taking Arum. If you encounter a product that contains it, do not use it without first checking with a pharmacist or doctor, and never prepare or eat the raw plant yourself.
