Drug & supplement interaction

Liverwort + Carvedilol

Carvedilol brand names: Coreg, Coreg CR.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Liverwort 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.

Liverwort 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 Liverwort 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 Liverwort 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.

What to actually watch for

No Interaction Found — But Data Suggests Liverwort and Carvedilol 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.

How to take them

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

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

“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.

About Liverwort

What is Liverwort?

Liverwort
  • Liver and gallbladder complaints
  • Digestive upset
  • Mild gallbladder discomfort
  • Respiratory or throat irritation
  • Skin conditions (traditional use)

Liverwort (Anemone hepatica) is a traditional herb once used for liver, gallbladder, and digestive complaints, but there is no reliable human research showing it works for any condition. The fresh plant belongs to the buttercup family and can irritate the skin and digestive tract, so it should only be used dried and with caution. Talk to your pharmacist or doctor before trying it.

Anemone hepatica · Ranunculaceae · Above-ground parts (leaves and flowers) · Tea, dried herb, tincture, capsules

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

Liverwort: dosing

There is no established or standardized dose for liverwort. Because it has not been studied in proper clinical trials, no safe and effective amount has been confirmed.If you choose to use a product that contains liverwort, follow the directions on the label and use only properly dried material, never the fresh plant. When in doubt, choose better-studied options with a clearer safety record.

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 Liverwort and Carvedilol Together: Common Questions

Is it safe to take Liverwort with Carvedilol?
We do not list a known interaction between Liverwort 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 Liverwort and Carvedilol have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Liverwort 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 Liverwort 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 — Liverwort is not one of them. The Carvedilol interaction page linked on this page lists every one, ranked by severity.
