Drug & supplement interaction

Atractylodes + Metoprolol

Metoprolol brand names: Lopressor, Toprol XL.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Atractylodes and Metoprolol 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 Metoprolol 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.

Atractylodes and Metoprolol

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 Metoprolol and Atractylodes 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.

How we checked

Why No Interaction Is Listed for Metoprolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Metoprolol is filed under 6 classifications — including beta-blockers, antihypertensive drugs, cytochrome p450 2d6 (cyp2d6) substrates. Atractylodes has documented interactions with 5 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), aromatase inhibitors (moderate) and hexobarbital (moderate) — and none of Metoprolol’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.

No Interaction Found — But Data Suggests Atractylodes and Metoprolol 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 Metoprolol Products Have a Food Rule — Atractylodes Should Not Break It

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

Administer once daily with food or after a meal.

From the Dosage and Administration section of the FDA label we read for Metoprolol — 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 Metoprolol page

“With metoprolol (Lopressor, Toprol XL), a beta-blocker for high blood pressure and heart problems, these interactions deserve genuine care, starting with the five rated major. Most entries pull blood pressure one way or the other: many supplements add to metoprolol's lowering effect and can drop pressure too far, while a few, tyramine…”

About Atractylodes

What is Atractylodes?

Atractylodes
  • Digestive upset and poor appetite
  • Bloating and fluid retention
  • General fatigue or 'weakness'
  • Diarrhea
  • Support within traditional formulas

Atractylodes is a root used for centuries in traditional Chinese, Japanese, and Thai medicine, mostly for digestive complaints and fatigue, often as part of multi-herb formulas. Modern research is still early and mostly from lab and animal studies, so its true benefits in people are not well proven. If you want to try it, talk with a pharmacist or doctor first, and avoid it during pregnancy and breastfeeding.

Atractylodes macrocephala; Atractylodes lancea · Asteraceae · Rhizome (root) · Dried root, powders, capsules, decoctions (teas), and part of traditional Chinese and Japanese herbal formulas

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

Atractylodes: dosing

There is no well-established standard dose for Atractylodes as a single supplement, and traditional amounts vary depending on the formula and the form used (dried root, powder, capsule, or decoction).If you choose to use it, follow the directions on the product label and do not exceed the suggested amount.

About Metoprolol

What Is Metoprolol Used For?

Brand names: Lopressor, Toprol XL

Metoprolol is used to treat several heart and blood pressure conditions. Metoprolol succinate extended-release tablets (including Toprol-XL) are approved for high blood pressure, angina pectoris (chest pain from the heart), and heart failure. Metoprolol tartrate tablets (including Lopressor) are approved for high blood pressure, angina, and — when used alongside intravenous metoprolol — to reduce the risk of cardiovascular death after a definite or suspected heart attack.

Metoprolol tartrate injection (intravenous form) is used in hemodynamically stable patients with a definite or suspected acute heart attack to reduce cardiovascular death, and is followed by oral metoprolol therapy. Lowering blood pressure with metoprolol reduces the risk of strokes and heart attacks.

Most-Reported Side Effects for Metoprolol

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Atractylodes and Metoprolol Together: Common Questions

Is it safe to take Atractylodes with Metoprolol?
We do not list a known interaction between Atractylodes and Metoprolol. 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 Atractylodes and Metoprolol have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Atractylodes and Metoprolol at the same time of day?
At least one FDA label for a product containing Metoprolol says to take it with food. If you take Atractylodes on an empty stomach out of habit, keep them separate and take Metoprolol with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Metoprolol products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Atractylodes and Metoprolol combination checked?
Interactions in our licensed database are recorded against drug classes. Metoprolol is filed under 6 classifications, and Atractylodes has documented interactions with 5 drug classes — none of Metoprolol'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 Atractylodes interact with any other medications?
Yes. Atractylodes has 801 documented drug interactions in our database — Metoprolol 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 Metoprolol interact with any supplements?
Yes. Metoprolol has documented interactions with 183 supplements in our database — Atractylodes is not one of them. The Metoprolol interaction page linked on this page lists every one, ranked by severity.
