Drug & supplement interaction

Pear + Mesalamine

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

No Known Interaction
The bottom line No known interaction

We found no known interaction between Pear 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.

Pear 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 Pear 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 Pear at all — not against Mesalamine, 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 Mesalamine’s Own FDA Label Lists

Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 6 of them are worth acting on rather than waiting out — marked below.

  • Kidney stones Worth acting on
  • Kidney problems Worth acting on

How to take them

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

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

Everything else you take

See Every Supplement That Interacts With Mesalamine

This page covers Pear 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 Pear

What is Pear?

  • Digestive health and constipation
  • Hydration and general nutrition
  • Cough and sore throat (traditional)
  • Hangover relief (traditional)
  • Antioxidant and heart health support

Pear is a common, nutritious fruit that provides fiber, water, vitamin C, and antioxidants, and it is a healthy part of most diets. Beyond its value as a food, evidence for pears as a medicinal supplement for specific conditions is limited, so enjoy it as part of a balanced diet rather than a treatment. If you have allergies or specific health concerns, check with your pharmacist or doctor.

Pyrus communis · Rosaceae · Fruit (commonly); leaves and fruit peel are sometimes used in traditional preparations · Fresh fruit, juice, dried fruit, fruit extracts, and powders

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

Pear: dosing

There is no established "medicinal dose" for pear, because it is mainly a food. Most people simply eat pears as part of a normal diet, such as one or more pieces of fruit per day.For pear juice, dried pear, or pear supplements and extracts, there is no standardized dose backed by strong evidence. Keep in mind that whole pears also provide fiber that juices and extracts may lack.

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 Pear and Mesalamine Together: Common Questions

Is it safe to take Pear with Mesalamine?
We do not list a known interaction between Pear 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.
Should I take Pear 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 Pear 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.
Does Mesalamine interact with any supplements?
Yes. Mesalamine has documented interactions with 17 supplements in our database — Pear is not one of them. The Mesalamine interaction page linked on this page lists every one, ranked by severity.
