Drug & supplement interaction

Hordenine + Insulin Glargine Recombinant

Insulin Glargine Recombinant brand name: Toujeo Solostar.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Hordenine and Insulin Glargine Recombinant 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 Insulin Glargine Recombinant

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 Insulin Glargine Recombinant 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 Insulin Glargine Recombinant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Insulin Glargine Recombinant is filed under 2 classifications — including antidiabetes drugs. 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 Insulin Glargine Recombinant’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.

What to actually watch for

No Interaction Found — But Data Suggests Hordenine and Insulin Glargine Recombinant 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.”

From our pharmacist’s overview on the Insulin Glargine Recombinant page

“If you inject insulin glargine (Toujeo Solostar), this list deserves real respect, because all 242 ingredients on it bear on the number you track daily, your blood sugar. Most of the 211 moderate entries add to insulin's glucose-lowering effect and can tip you into hypoglycemia, a dangerous low, while a smaller group pushes sugar upwar…”

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.

Taking Hordenine and Insulin Glargine Recombinant Together: Common Questions

Is it safe to take Hordenine with Insulin Glargine Recombinant?

Do Hordenine and Insulin Glargine Recombinant 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.

How was the Hordenine and Insulin Glargine Recombinant combination checked?

Insulin Glargine Recombinant is filed under 2 classifications, and Hordenine has documented interactions with 3 drug classes — none of Insulin Glargine Recombinant'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 — Insulin Glargine Recombinant is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
