Mesalamine brand names: Pentasa, Asacol, Canasa, Rowasa, Lialda, and others.

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 Allspice and Mesalamine 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 Mesalamine 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.

Allspice and Mesalamine

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 Mesalamine and Allspice 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 Mesalamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Mesalamine is filed under a single classification — oral drugs. Allspice has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Mesalamine’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.

Keep it in perspective

Allspice Does Interact With Other Medications

What to actually watch for

No Interaction Found — But Data Suggests Allspice and Mesalamine 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.

  • An allergic reaction Worth acting on Additional detail

    “Orally and topically, allspice can cause allergic dermatitis in sensitive people. A case report describes a 41-year-old female with a history of allergic reactions to certain foods and drinks, with symptoms including lip angioedema, generalized hives and urticaria, vomiting, difficulty breathing, sneezing, ocular pruritus, and lacrimation, which responded to oral diphenhydramine.”

How to take them

Some Mesalamine Products Have a Food Rule — Allspice Should Not Break It

At least one FDA label for a product containing Mesalamine says to take it with food. If you take Allspice on an empty stomach out of habit, keep them separate — and take Mesalamine 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 Mesalamine 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 ) Administer mesalamine delayed-release tablets with food.

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

See Every Supplement That Interacts With Mesalamine

This page covers Allspice only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mesalamine page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Mesalamine page

“Activated charcoal is the one entry here I would treat as a genuine problem for anyone taking mesalamine (Asacol, Lialda, Pentasa, and others). It is the lone major-rated interaction among the 17 on file, because charcoal soaks up drugs in the gut and can pull mesalamine out of the picture before it does its job.”

About Allspice

What is Allspice?

Allspice
  • Digestive upset and gas
  • Muscle and joint pain (topical)
  • Toothache and oral discomfort
  • Antimicrobial uses
  • Flavoring in food and drinks

Allspice is a popular cooking spice from a Caribbean evergreen tree that has long been used in folk medicine for digestion, pain, and infections. There is very little high-quality human research to support these medicinal uses, so it is best thought of as a flavorful food rather than a proven treatment. Amounts used in cooking are generally considered safe, but concentrated extracts and the essential oil should be used carefully.

Pimenta dioica · Myrtaceae · Dried unripe berries, leaves, and essential oil · Whole or ground spice, tea, extract, essential oil

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

Allspice: dosing

There is no established standard medicinal dose for allspice. Most people only encounter it in the small amounts used to flavor food, which are considered safe.For supplements, teas, or extracts, there is not enough reliable research to recommend a specific amount. If you choose to use a product, follow the directions on the label and do not exceed them.The essential oil is highly concentrated and should only be used externally and well diluted, never taken by mouth without professional guidance.

About Mesalamine

What Is Mesalamine Used For?

Brand names: Pentasa, Asacol, Canasa, Rowasa, Lialda, Delzicol

Mesalamine is used to treat mildly to moderately active ulcerative colitis — a condition where the lining of the large intestine becomes inflamed and ulcerated. Depending on the product and formulation, it can be used to bring the disease under control (induction of remission) and/or to keep it from coming back (maintenance of remission).

Different products target different parts of the lower digestive tract. Oral forms (tablets and capsules) treat the colon more broadly. Rectal forms — including enemas (ROWASA, sfROWASA, mesalamine rectal suspension) — are used for distal ulcerative colitis, proctosigmoiditis, or proctitis (inflammation limited to the lower end of the colon or rectum). Rectal suppositories (CANASA, mesalamine rectal suppositories) are specifically for ulcerative proctitis (inflammation of the rectum only).

Taking Allspice and Mesalamine Together: Common Questions

Is it safe to take Allspice with Mesalamine?
We do not list a known interaction between Allspice and Mesalamine. 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 Allspice and Mesalamine 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 Allspice and Mesalamine at the same time of day?
At least one FDA label for a product containing Mesalamine says to take it with food. If you take Allspice on an empty stomach out of habit, keep them separate and take Mesalamine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Mesalamine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Allspice and Mesalamine combination checked?
Interactions in our licensed database are recorded against drug classes. Mesalamine is filed under 1 classification, and Allspice has documented interactions with 1 drug class — none of Mesalamine'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 Allspice interact with any other medications?
Yes. Allspice has 122 documented drug interactions in our database — Mesalamine 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 Mesalamine interact with any supplements?
Yes. Mesalamine has documented interactions with 17 supplements in our database — Allspice is not one of them. The Mesalamine interaction page linked on this page lists every one, ranked by severity.
