The bottom line No known interaction

We found no known interaction between Coriander and Alvimopan 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.

Coriander and Alvimopan

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 Alvimopan and Coriander 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.

Coriander safety at a glance

Coriander overall Generally safe Coriander is generally safe in normal food amounts for most people.
Pregnancy Use caution Food amounts are likely fine, but concentrated medicinal doses or essential oil should be avoided without medical advice.
Breastfeeding Use caution Food amounts are likely fine, but medicinal doses lack safety data, so use caution.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Alvimopan

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alvimopan is filed under 2 classifications — p-glycoprotein substrates, oral drugs. Coriander has documented interactions with 4 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and cns depressants (moderate) — and none of Alvimopan’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

What Coriander Itself Has Been Linked To

This is not an interaction — nothing below involves Alvimopan. It is the side-effect record for Coriander on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Coriander, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Wheezing / Hives Worth acting on Additional detail

    “A case of anaphylactic reaction characterized by generalized urticaria, conjunctivitis, oropharyngeal angioedema, and bronchospasms has been reported in a 25-year-old spice worker who consumed food containing coriander fruit. The digestive spice allergy was attributed to sensitization to coriander caused by occupational exposure to coriander fruit, powder, and dust.”

Everything above comes from the Natural Medicines adverse-effect record for Coriander — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Alvimopan’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Alvimopan column appears here.

Overlapping uses

What Alvimopan Is Prescribed For, and What Coriander Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Alvimopan is a prescription medicine with approved uses on its FDA label. Coriander is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Alvimopan is prescribed for: Alvimopan capsules are used in hospitals to help the digestive tract recover more quickly after surgery that involves removing part of the bowel (partial bowel resection with primary anastomosis — meaning the remaining ends are reconnected). After this type of surgery, the bowel often temporarily stops working, a condition called postoperative ileus. This medication is only given during a short hospital stay and is not for long-term or home use.

Coriander has been studied for:

  • Constipation studied, not established Coriander has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Coriander for constipation

    Oral coriander has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Alvimopan on your own; if you are taking Coriander for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

The most serious there right now: Activated Charcoal (major), St. John's Wort (major), Bitter Melon (moderate), Black Pepper (moderate) and Bulbine Natalensis (moderate).

From our pharmacist’s overview on the Alvimopan page

“Alvimopan (Entereg) is given for a few days after bowel surgery to help the gut start moving again, and its supplement list warrants genuine care, with two entries rated major. St.”

About Coriander

What is Coriander?

Coriander
  • Digestive upset and gas
  • Appetite stimulation
  • Mild antimicrobial (topical)
  • Diarrhea and IBS symptoms
  • General flavoring and traditional remedy

Coriander (also called cilantro) is a common cooking herb and spice that has long been used in traditional medicine for digestive complaints. As a food it is generally safe for most people, but high-quality human studies supporting its medicinal benefits are limited. Talk with your pharmacist or doctor before using concentrated extracts or essential oils.

Coriandrum sativum · Apiaceae · Seeds (fruit), leaves, and essential oil · Culinary spice and herb, tea, capsules, tincture/extract, essential oil

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

Coriander: dosing

There is no standardized or proven medicinal dose of coriander. Amounts used in studies and traditional remedies vary widely depending on the form (tea, seeds, capsule, or oil).If you choose to use a coriander supplement, follow the directions on the product label and do not exceed the recommended amount. Essential oils are very concentrated and should not be taken by mouth without professional guidance.

Taking Coriander and Alvimopan Together: Common Questions

Is it safe to take Coriander with Alvimopan?
We do not list a known interaction between Coriander and Alvimopan. 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.
Are Coriander and Alvimopan used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Coriander in each. That is a conversation for your prescriber, especially if Alvimopan is being adjusted to a target.
How was the Coriander and Alvimopan combination checked?
Interactions in our licensed database are recorded against drug classes. Alvimopan is filed under 2 classifications, and Coriander has documented interactions with 4 drug classes — none of Alvimopan'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 Coriander interact with any other medications?
Yes. Coriander has 717 documented drug interactions in our database — Alvimopan 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 Alvimopan interact with any supplements?
Yes. Alvimopan has documented interactions with 54 supplements in our database — Coriander is not one of them. The Alvimopan interaction page linked on this page lists every one, ranked by severity.
