The bottom line No known interaction

We found no known interaction between Zeaxanthin 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.

Zeaxanthin 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 Zeaxanthin 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. Zeaxanthin has documented interactions with 1 drug class — the most serious being antidiabetes 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

What Mesalamine’s Own FDA Label Lists

This is not an interaction — none of it involves Zeaxanthin. These are the most notable effects listed in the ADVERSE REACTIONS section of Mesalamine’s own FDA label, for the medication by itself. 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
  • Anemia Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Sun sensitivity
  • Bloating or gas
  • Stomach pain
  • Diarrhea

Showing the 10 most notable of 12 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Mesalamine. Read the label on DailyMed › Zeaxanthin’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Zeaxanthin side to compare — that is a limit of the record, not a statement that Zeaxanthin has no side effects.

Special populations

Zeaxanthin in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally and appropriately in amounts found in foods. Zeaxanthin is found in breast milk and levels correlate with infant status. There is insufficient reliable information available about the safety of supplemental zeaxanthin.

How to take them

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

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

Overlapping uses

What Mesalamine Is Prescribed For, and What Zeaxanthin Has Been Studied For

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

Mesalamine is prescribed for: 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.

Read the rest of what Mesalamine is prescribed for

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).

Zeaxanthin has been studied for:

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

    Zeaxanthin for ulcerative colitis

    It is unclear if oral zeaxanthin is beneficial for ulcerative colitis.

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 Mesalamine on your own; if you are taking Zeaxanthin for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Mesalamine

This page covers Zeaxanthin 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 Zeaxanthin

What is Zeaxanthin?

Zeaxanthin
  • Eye and macular health
  • Age-related macular degeneration (AMD)
  • Protection from blue light
  • General antioxidant support
  • Cataract risk reduction

Zeaxanthin is a carotenoid pigment that, along with lutein, concentrates in the macula of the eye and may help support long-term eye health. The strongest evidence relates to slowing progression of advanced age-related macular degeneration when combined with other nutrients, while many other uses remain unproven. It is generally well tolerated, but talk to your pharmacist or doctor before starting any supplement.

Pigment found in leafy greens, corn, eggs, and other colorful plants and foods · Capsules, softgels, tablets (often combined with lutein), and as part of multivitamin or eye-health formulas

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

Zeaxanthin: dosing

There is no official, universally established dose of zeaxanthin. In eye-health research, it has typically been studied as part of a nutrient combination that includes lutein, often at much smaller amounts than lutein.Because products vary widely, the best approach is to follow the directions on the product label. Zeaxanthin is frequently combined with lutein, so check the full ingredient list.

Taking Zeaxanthin and Mesalamine Together: Common Questions

Is it safe to take Zeaxanthin with Mesalamine?
We do not list a known interaction between Zeaxanthin 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 Zeaxanthin 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 Zeaxanthin 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.
Are Zeaxanthin and Mesalamine 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 Zeaxanthin in each. That is a conversation for your prescriber, especially if Mesalamine is being adjusted to a target.
How was the Zeaxanthin and Mesalamine combination checked?
Interactions in our licensed database are recorded against drug classes. Mesalamine is filed under 1 classification, and Zeaxanthin 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 Zeaxanthin interact with any other medications?
Yes. Zeaxanthin has 86 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 — Zeaxanthin is not one of them. The Mesalamine interaction page linked on this page lists every one, ranked by severity.
