Drug & supplement interaction

Ipecac + Lonafarnib

Lonafarnib brand name: Zokinvy.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Ipecac 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.

Interaction report

Ipecac 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 Ipecac 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.

Ipecac safety at a glance

Ipecac overall Avoid No longer recommended for home or routine use due to risk of serious harm and lack of proven benefit.

Pregnancy Likely Unsafe When used orally; ipecac is a potential uterine stimulant. Read the full pregnancy detail

Breastfeeding Avoid Safety is not established, so it should be avoided while breastfeeding.

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.

How we checked

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. Ipecac has documented interactions with 1 drug class — the most serious being activated charcoal (major) — 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.

What to actually watch for

No Interaction Found — But Data Suggests Ipecac and Lonafarnib 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. One of them is worth acting on rather than waiting out — marked below.

Bleeding or bruising Worth acting on Additional detail
Ipecac
“Orally, ipecac syrup can cause nausea, vomiting, diarrhea, GI irritation, dizziness, hypotension, dyspnea, and tachycardia. Rarely, it can also cause intracerebral hemorrhage, pneumomediastinum, retropneumoperitoneum, esophageal bleeding (3,6,11,13,15,18,56390,56440,56447,56448). Chronic use is associated with myopathies and death (6,18,56391,56412,56413,56414,56416,56421,56422,56424).”

How to take them

Some Lonafarnib Products Have a Food Rule — Ipecac Should Not Break It

At least one FDA label for a product containing Lonafarnib says to take it with food. If you take Ipecac 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.

Everything else you take

See Every Supplement That Interacts With Lonafarnib

This page covers Ipecac 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 Ipecac

What is Ipecac?

Inducing vomiting after poisoning (historical)
Cough and chest congestion (expectorant)
Nausea and vomiting (homeopathic use)
Amebic dysentery (historical)

Ipecac comes from the root of a South American plant and was once widely used as syrup of ipecac to make people vomit after swallowing poison. Medical groups no longer recommend it for poisoning because it is not proven helpful and can be dangerous, and misuse has caused serious harm. There is no safe, established home use for ipecac today, and you should call Poison Control rather than reach for it.

Carapichea ipecacuanha · Rubiaceae · Dried root and rhizome · Syrup (syrup of ipecac), tincture, liquid extract, homeopathic preparations

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

Ipecac: dosing

There is no recommended over-the-counter dose for ipecac because it is no longer advised for home use. We will not provide dosing amounts here, since using ipecac on your own can be harmful.If you have a product on hand, do not use it for poisoning—instead, call your Poison Control center or emergency services right away, as they can give the safest, up-to-date advice.For any homeopathic ipecac product, follow the directions on the label, but be aware these products are not proven to work.

Taking Ipecac and Lonafarnib Together: Common Questions

Is it safe to take Ipecac with Lonafarnib?

We do not list a known interaction between Ipecac and Lonafarnib. 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 Ipecac and Lonafarnib 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.

Should I take Ipecac and Lonafarnib at the same time of day?

At least one FDA label for a product containing Lonafarnib says to take it with food. If you take Ipecac on an empty stomach out of habit, keep them separate and take Lonafarnib with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Lonafarnib products can differ — so check the directions on your own box. This is about absorption, not an interaction.

How was the Ipecac and Lonafarnib combination checked?

Interactions in our licensed database are recorded against drug classes. Lonafarnib is filed under 5 classifications, and Ipecac has documented interactions with 1 drug class — none of Lonafarnib'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 Ipecac interact with any other medications?

Yes. Ipecac has 2 documented drug interactions in our database — Lonafarnib 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 Lonafarnib interact with any supplements?

Yes. Lonafarnib has documented interactions with 160 supplements in our database — Ipecac is not one of them. The Lonafarnib interaction page linked on this page lists every one, ranked by severity.
