Drug & supplement interaction

German Ipecac + Carvedilol

Carvedilol brand names: Coreg, Coreg CR.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between German Ipecac and Carvedilol 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 Carvedilol 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

German Ipecac and Carvedilol

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 Carvedilol and German 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.

Worth understanding: our licensed dataset holds no drug-interaction record for German Ipecac at all — not against Carvedilol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

No Interaction Found — But Data Suggests German Ipecac and Carvedilol 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.

  • Vomiting Additional detail

    “Orally, high doses of German ipecac may cause vomiting, apnea, and cardiac arrest. Seed extracts may cause advancing paralysis of the central nervous system (18).”

How to take them

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

At least one FDA label for a product containing Carvedilol says to take it with food. If you take German Ipecac on an empty stomach out of habit, keep them separate — and take Carvedilol 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 Carvedilol 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.

2 DOSAGE AND ADMINISTRATION COREG should be taken with food to slow the rate of absorption and reduce the incidence of orthostatic effects.

From the Dosage and Administration section of the FDA label we read for Carvedilol — 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.

From our pharmacist’s overview on the Carvedilol page

“People take carvedilol (Coreg) for heart failure and high blood pressure, conditions where a sudden swing in pressure or heart rate matters, and its supplement list runs to 211 ingredients, so this one calls for genuine care. More than half of those entries lower blood pressure on their own, fish oil and celery seed among them, and can…”

About German Ipecac

What is German Ipecac?

  • To cause vomiting (emetic)
  • Loosening chest congestion
  • Nausea (in homeopathic dilutions)
  • Cough and bronchial complaints

"German Ipecac" is an uncommon name, and the source plant is not clearly established, so be very cautious about any product sold under this name. True ipecac is a powerful emetic that is no longer recommended for treating poisoning and can be dangerous if misused. Talk to a pharmacist or doctor before using any product labeled as ipecac.

Root and rhizome · Tincture, syrup, homeopathic preparations, dried root

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

German Ipecac: dosing

There is no established, standardized dose for a product called "German Ipecac," and reliable dosing information for this specific name does not exist. Never increase the dose or repeat it on your own. Keep all such products out of reach of children.

About Carvedilol

What Is Carvedilol Used For?

Brand names: Coreg, Coreg CR

Carvedilol is used to treat three main conditions: mild-to-severe chronic heart failure, high blood pressure (hypertension), and reduced heart pumping function (left ventricular dysfunction) in people who have survived a heart attack. For heart failure, it is usually prescribed alongside other medications such as diuretics, ACE inhibitors, and digitalis to help people live longer and reduce the chance of hospital stays.

For people who have had a heart attack and whose heart is not pumping as well as it should, carvedilol is used to lower the risk of dying from heart-related causes. For high blood pressure, it can be used on its own or combined with other blood pressure medicines.

Most-Reported Side Effects for Carvedilol

Taking German Ipecac and Carvedilol Together: Common Questions

Is it safe to take German Ipecac with Carvedilol?
We do not list a known interaction between German Ipecac and Carvedilol. 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 German Ipecac and Carvedilol 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. 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 German Ipecac and Carvedilol at the same time of day?
At least one FDA label for a product containing Carvedilol says to take it with food. If you take German Ipecac on an empty stomach out of habit, keep them separate and take Carvedilol with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Carvedilol products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Carvedilol interact with any supplements?
Yes. Carvedilol has documented interactions with 211 supplements in our database — German Ipecac is not one of them. The Carvedilol interaction page linked on this page lists every one, ranked by severity.
