Chicory and Naltrexone Hydrochloride, Oxycodone Hydrochloride

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 Naltrexone Hydrochloride, Oxycodone Hydrochloride and Chicory 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 Naltrexone Hydrochloride, Oxycodone Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Naltrexone Hydrochloride, Oxycodone Hydrochloride is filed under 7 classifications — including narcotic drugs, cytochrome p450 2d6 (cyp2d6) substrates, cns depressants. Chicory has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Naltrexone Hydrochloride, Oxycodone Hydrochloride’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.

“Alcohol tops this list. Beer and wine both carry major, well-documented interactions with Troxyca ER (naltrexone and oxycodone hydrochloride), an extended-release opioid, because adding a second sedative to an opioid can slow breathing, not just deepen drowsiness.”

About Chicory

What is Chicory?

Chicory
  • Constipation and digestive health
  • Source of prebiotic fiber (inulin)
  • Coffee substitute
  • Liver and gallbladder support
  • Appetite and blood sugar (traditional)

Chicory is best known as a caffeine-free coffee substitute and as a source of inulin, a soluble prebiotic fiber that may support digestion and regularity. Strong human evidence for most other traditional uses (like liver, gallbladder, or skin conditions) is limited. It is generally well tolerated, but the inulin can cause gas and bloating, and people allergic to ragweed or related plants should be cautious.

Cichorium intybus · Asteraceae · Root and leaves (the root is the most common medicinal part) · Roasted root (coffee substitute), inulin fiber powder, capsules, tea, liquid extract

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

Chicory: dosing

There is no official standardized dose for chicory. The right amount depends on the form—roasted root for coffee, inulin fiber powder, capsules, or tea—and on the product's concentration.For inulin fiber, it is generally wise to start with a small amount and increase slowly to reduce gas and bloating, and to drink plenty of water.
