Drug & supplement interaction

Glucosamine + Fluvoxamine

Fluvoxamine brand name: Luvox.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Glucosamine and Fluvoxamine 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 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.

Glucosamine and Fluvoxamine

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 Fluvoxamine and Glucosamine 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.

Glucosamine safety at a glance

Glucosamine overall Use caution Generally well tolerated by most adults, but quality and benefit vary and certain people should be careful.
Pregnancy Avoid There is not enough safety information, so it is best to avoid during pregnancy.
Breastfeeding Avoid Not enough is known about safety while breastfeeding, so avoid unless your doctor advises otherwise.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Fluvoxamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fluvoxamine is filed under 14 classifications — including antidepressant drugs, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Glucosamine has documented interactions with 4 drug classes — the most serious being warfarin (coumadin) (major), topoisomerase ii inhibitors (moderate) and acetaminophen (tylenol, others) (minor) — and none of Fluvoxamine’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.

No Interaction Found — But Data Suggests Glucosamine and Fluvoxamine 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.

  • Bloating or gas / Diarrhea / Nausea Additional detail

    Glucosamine

    “Orally, all forms of glucosamine seem to be well tolerated. Topically and rectally, N-acetyl glucosamine also seems to be well tolerated. Intramuscularly, glucosamine sulfate seems to be well tolerated.”

    Glucosamine · Natural Medicines adverse-effect record, reported in constipation.

    “Orally, glucosamine has been associated with gastrointestinal problems, including epigastric and abdominal pain, cramps, heartburn, diarrhea, nausea, dyspepsia, vomiting, constipation, and flatulence. In older persons, use of glucosamine sulfate is associated with oral dryness. In a clinical trial, a case of Helicobacter pylori gastritis was considered probably related to the use of glucosamine hydrochloride.”

See Every Supplement That Interacts With Fluvoxamine

This page covers Glucosamine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Fluvoxamine page lists 193 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Lithium (major), 1,3-dmaa (moderate), 5-htp (moderate) and Acacia Rigidula (moderate).

By severity: 2 major · 151 moderate · 40 minor.

From our pharmacist’s overview on the Fluvoxamine page

“Fluvoxamine (Luvox), an SSRI used for OCD and depression, carries an interaction list that deserves genuinely careful reading. Two entries matter most: lithium, which alongside a serotonin-raising drug like fluvoxamine can tip toward serotonin syndrome, a dangerous excess of serotonin, and activated charcoal, which can soak up the medi…”

About Glucosamine

What is Glucosamine?

Glucosamine
  • Osteoarthritis
  • Joint pain and stiffness
  • Cartilage support
  • Knee and hip joint health

Glucosamine is a natural compound found in cartilage and joint fluid, and it is one of the most popular supplements for osteoarthritis, especially of the knee. The evidence is mixed, with some people getting modest relief while others get little to no benefit. It is generally well tolerated, but talk to your pharmacist or doctor before starting it, especially if you have a shellfish allergy or diabetes.

Derived from shellfish exoskeletons (shrimp, crab, lobster) or made synthetically; also from fungal sources · Capsules, tablets, powders, liquids; often combined with chondroitin or MSM

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

Glucosamine: dosing

There is no single official dose of glucosamine, and the right amount can depend on the form and product. If you do not notice any benefit after a reasonable trial of a couple of months, it is worth discussing whether to continue.

From our Glucosamine monograph — the full record covers uses, side effects and every documented interaction.

About Fluvoxamine

What Is Fluvoxamine Used For?

Brand name: Luvox

Both fluvoxamine maleate tablets and Fluvoxamine Maleate extended-release capsules are approved to treat obsessive-compulsive disorder (OCD) — a condition marked by unwanted, recurring thoughts (obsessions) and/or repetitive behaviors (compulsions) that cause significant distress or interfere with daily life.

Fluvoxamine maleate tablets are approved for adults and for children and adolescents ages 8 to 17. Fluvoxamine Maleate extended-release capsules are approved for adults with OCD; their use in pediatric patients naive to fluvoxamine requires special prescriber consideration regarding the lowest available dose.

Taking Glucosamine and Fluvoxamine Together: Common Questions

Is it safe to take Glucosamine with Fluvoxamine?
We do not list a known interaction between Glucosamine and Fluvoxamine. 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 Glucosamine and Fluvoxamine have any of the same side effects?
Yes — our sources link each of them separately to 9 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.
How was the Glucosamine and Fluvoxamine combination checked?
Interactions in our licensed database are recorded against drug classes. Fluvoxamine is filed under 14 classifications, and Glucosamine has documented interactions with 4 drug classes — none of Fluvoxamine'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 Glucosamine interact with any other medications?
Yes. Glucosamine has 170 documented drug interactions in our database — Fluvoxamine 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 Fluvoxamine interact with any supplements?
Yes. Fluvoxamine has documented interactions with 193 supplements in our database — Glucosamine is not one of them. The Fluvoxamine interaction page linked on this page lists every one, ranked by severity.
