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 Beta-cryptoxanthin and Zileuton 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 Zileuton states a food rule worth keeping to.

Interaction report

Beta-cryptoxanthin and Zileuton

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 Zileuton and Beta-cryptoxanthin 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 Beta-cryptoxanthin at all — not against Zileuton, 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 Zileuton’s Own FDA Label Lists

This is not an interaction — none of it involves Beta-cryptoxanthin. These are the most notable effects listed in the ADVERSE REACTIONS section of Zileuton’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. 3 of them are worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on mentioned in 11.9% of FDA reports for Zileuton
  • Liver problems Worth acting on
  • An allergic reaction Worth acting on
  • Stomach upset
  • Stomach pain
  • Nausea mentioned in 6.3% of FDA reports for Zileuton
  • Diarrhea
  • A skin rash
  • Vomiting

From the ADVERSE REACTIONS section of the FDA label for Zileuton. Read the label on DailyMed › Where a percentage is shown, it is the share of 637 voluntary FDA FAERS reports for Zileuton that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Beta-cryptoxanthin’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Beta-cryptoxanthin side to compare — that is a limit of the record, not a statement that Beta-cryptoxanthin has no side effects.

How to take them

Some Zileuton Products Have a Food Rule — Beta-cryptoxanthin Should Not Break It

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

For ease of administration, ZYFLO may be taken with meals and at bedtime.

From the Dosage and Administration section of the FDA label we read for Zileuton — 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 Zileuton Is Prescribed For, and What Beta-cryptoxanthin Has Been Studied For

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

Zileuton is prescribed for: Zileuton is used for the ongoing prevention and treatment of asthma in adults and adolescents aged 12 and older. It is a maintenance medicine — meaning it is taken regularly to keep asthma under control, not to stop an asthma attack once it has started. Zyflo (the tablet form) and zileuton extended-release tablets are both approved for this same purpose. Neither form should be used to treat a sudden asthma attack.

However, both can be continued during a flare-up of asthma while you also use your rescue inhaler.

Beta-cryptoxanthin has been studied for:

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

    Beta-cryptoxanthin for asthma

    It is unclear if dietary beta-cryptoxanthin intake can reduce the risk of asthma.

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

About Beta-cryptoxanthin

What is Beta-cryptoxanthin?

  • Antioxidant support
  • Eye health
  • Bone health
  • Vitamin A source
  • General wellness

Beta-cryptoxanthin is a natural orange-red plant pigment (a carotenoid) found in fruits like oranges, tangerines, and papaya, and it can be turned into vitamin A in the body. Diets rich in beta-cryptoxanthin are linked in some studies to better bone and lung health, but the evidence for supplements is limited. For most people, getting it from colorful fruits and vegetables is the safest and best-studied approach.

Naturally found in fruits and vegetables; also made as a supplement · Capsules, softgels, and multivitamin/carotenoid blends; naturally present in whole foods

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

Beta-cryptoxanthin: dosing

There is no established standard supplement dose for beta-cryptoxanthin. Most research reflects amounts obtained through a normal diet rich in fruits and vegetables rather than from pills.If you choose to take a supplement, follow the directions on the product label and do not exceed the recommended amount.

Taking Beta-cryptoxanthin and Zileuton Together: Common Questions

Is it safe to take Beta-cryptoxanthin with Zileuton?
We do not list a known interaction between Beta-cryptoxanthin and Zileuton. 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 Beta-cryptoxanthin and Zileuton at the same time of day?
At least one FDA label for a product containing Zileuton says to take it with food. If you take Beta-cryptoxanthin on an empty stomach out of habit, keep them separate and take Zileuton with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Zileuton products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Beta-cryptoxanthin and Zileuton 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 Beta-cryptoxanthin in each. That is a conversation for your prescriber, especially if Zileuton is being adjusted to a target.
Does Zileuton interact with any supplements?
Yes. Zileuton has documented interactions with 213 supplements in our database — Beta-cryptoxanthin is not one of them. The Zileuton interaction page linked on this page lists every one, ranked by severity.
