The bottom line No known interaction

We found no known interaction between Hordenine and Meloxicam 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.

Hordenine and Meloxicam

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 Meloxicam and Hordenine 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 Meloxicam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Meloxicam is filed under 7 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, organic anion transporter 3 (oat3) substrates. Hordenine has documented interactions with 3 drug classes — the most serious being monoamine oxidase inhibitors (maois) (moderate), stimulant drugs (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (minor) — and none of Meloxicam’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 Hordenine and Meloxicam May Share a Side Effect

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. One of them is worth acting on rather than waiting out — marked below.

    Hordenine

    “No clinical studies have evaluated the safety of hordenine in humans. However, hordenine is structurally similar to the stimulants N-methyltyramine and synephrine, which are found in bitter orange. Theoretically, hordenine may cause stimulant-related side effects similar to these compounds, including tachycardia and hypertension.”

    Meloxicam

    Listed in the ADVERSE REACTIONS section of the FDA label for Meloxicam. Read the label on DailyMed ›

Reported for Hordenine but not commonly for Meloxicam: a fast or pounding heartbeat.

Effects for Meloxicam come from the ADVERSE REACTIONS section of its FDA label; effects for Hordenine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 57,978 voluntary FDA FAERS reports for Meloxicam that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Meloxicam

This page covers Hordenine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Meloxicam page lists 113 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Siberian Cocklebur (major) and Wine (major).

By severity: 5 major · 81 moderate · 27 minor.

From our pharmacist’s overview on the Meloxicam page

“Most people take meloxicam (Mobic) daily for arthritis pain, which gives supplement interactions time to add up, so I read this list with real vigilance. Five of the 113 ingredients on file carry a major rating, and two are simply beer and wine, because alcohol plus any NSAID raises the odds of stomach bleeding.”

About Hordenine

What is Hordenine?

Hordenine
  • Energy and stimulation
  • Athletic and workout performance
  • Weight loss/fat burning
  • Focus and mood
  • Appetite control

Hordenine is a natural alkaloid found in barley and some cacti that is marketed as a stimulant for energy, focus, and fat loss, but solid human evidence for these benefits is lacking. Its safety in people has not been well studied, so caution is warranted, and it should be avoided in pregnancy, breastfeeding, and by people with heart conditions.

Alkaloid isolated from plants such as barley sprouts and certain cacti · Capsules, tablets, powders (often in pre-workout and 'fat burner' blends)

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

Hordenine: dosing

There is no established, well-studied dose for hordenine. The amounts found in supplements vary widely, and they have not been tested for safety or effectiveness in proper human trials.If you choose to use a product containing hordenine, follow the label instructions and do not exceed them. Be aware that it is often mixed with caffeine and other stimulants, so the total stimulant load may be higher than it appears.

About Meloxicam

What Is Meloxicam Used For?

Brand names: Mobic, Vivlodex, Qmiiz ODT, Anjeso

Meloxicam tablets and oral suspension treat the signs and symptoms of osteoarthritis, rheumatoid arthritis, and juvenile rheumatoid arthritis (JRA). The oral suspension and Zybic™ oral suspension are approved for JRA in children 2 years and older; meloxicam tablets are approved for JRA in patients who weigh at least 60 kg. Meloxicam capsules are approved specifically for the management of osteoarthritis pain.

Two IV (intravenous) formulations — QAMZOVA and XIFYRM — are indicated for adults for the management of moderate-to-severe pain, used alone or with non-NSAID pain relievers. Because these IV forms take time to reach full effect, they are not recommended when rapid pain relief is needed.

Most-Reported Side Effects for Meloxicam

From FAERS, the FDA’s public side-effect reporting system (57,978 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 4,761 reports
Arthralgia 4,368 reports

Taking Hordenine and Meloxicam Together: Common Questions

Is it safe to take Hordenine with Meloxicam?
We do not list a known interaction between Hordenine and Meloxicam. 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 Hordenine and Meloxicam have any of the same side effects?
Yes — our sources link each of them separately to one 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 Hordenine and Meloxicam combination checked?
Interactions in our licensed database are recorded against drug classes. Meloxicam is filed under 7 classifications, and Hordenine has documented interactions with 3 drug classes — none of Meloxicam'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 Hordenine interact with any other medications?
Yes. Hordenine has 329 documented drug interactions in our database — Meloxicam 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 Meloxicam interact with any supplements?
Yes. Meloxicam has documented interactions with 113 supplements in our database — Hordenine is not one of them. The Meloxicam interaction page linked on this page lists every one, ranked by severity.
