Barley and Lixisenatide

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 Lixisenatide and Barley 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 Lixisenatide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lixisenatide is filed under a single classification — antidiabetes drugs. Barley has documented interactions with 1 drug class — the most serious being triclabendazole (egaten) (moderate) — and none of Lixisenatide’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

What Barley Itself Has Been Linked To

This is not an interaction — nothing below involves Lixisenatide. It is the side-effect record for Barley on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Barley, this list is the first place to look. 4 entries are worth acting on rather than waiting out — marked below.

  • Fainting / Chest pain / Shortness of breath / A severe allergic reaction Worth acting on Additional detail

    “Orally, consumption of beer has been reported to cause allergic reactions in sensitive individuals. Symptoms included tingling in the face, lip, and tongue, angioedema, generalized urticaria, chest tightness, dyspnea, cough, fainting, and rhinoconjunctivitis.

Overlapping uses

What Lixisenatide Is Prescribed For, and What Barley Has Been Studied For

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

Barley has been studied for:

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

    Barley for diabetes

    Although there has been interest in using oral barley for diabetes, there is insufficient reliable information about the clinical effects of barley for this purpose.

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

From our pharmacist’s overview on the Lixisenatide page

“Lixisenatide (Adlyxin) is injected to lower blood sugar in type 2 diabetes, and nearly everything on this page acts on blood sugar too, which is why I would treat the list with genuine care rather than a shrug. Most of the entries, from bitter melon and fenugreek to both types of ginseng, can push glucose lower still and raise the odds…”

About Barley

What is Barley?

Barley
  • High cholesterol
  • Heart health support
  • Blood sugar support
  • Digestive regularity and fiber
  • General nutrition

Barley is a nutritious whole grain that is a good source of soluble fiber called beta-glucan, which has solid evidence for modestly lowering LDL ('bad') cholesterol when eaten regularly. It is safe as a food for most people, but those with celiac disease or gluten sensitivity should avoid it since it contains gluten. Talk to your pharmacist or doctor before using concentrated barley supplements, especially if you have a health condition.

Hordeum vulgare · Poaceae · Grain (seed), and sometimes young leaves/grass and bran · Whole grain, flour, flakes, barley bran, beta-glucan supplements, barley grass powder, tea, and capsules

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

Barley: dosing

There is no single official supplement dose for barley. For cholesterol benefits, research has generally used a few grams of barley beta-glucan per day, taken as part of the diet, but the exact amount can vary by product.Because products differ widely in strength and form, the best approach is to follow the directions on the product label.

About Lixisenatide Injection

What Is Lixisenatide Injection Used For?

Brand name: Adlyxin

  • Lixisenatide injection is used along with diet and exercise to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Lixisenatide injection is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood). Lixisenatide is not used instead of insulin to treat people with diabetes who need insulin. Lixisenatide injection is in a class of medications called incretin mimetics. It works by stimulating the pancreas to secrete insulin when blood sugar levels are high. Insulin helps move sugar from the blood into other body tissues where it is used for energy. Lixisenatide injection also slows the emptying of the stomach and causes a decrease in appetite.

  • Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Using medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.

  • Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with lixisenatide injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) to obtain the Medication Guide.

Taking Barley and Lixisenatide Together: Common Questions

Is it safe to take Barley with Lixisenatide?
We do not list a known interaction between Barley and Lixisenatide. 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.
Are Barley and Lixisenatide 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 Barley in each. That is a conversation for your prescriber, especially if Lixisenatide is being adjusted to a target.
How was the Barley and Lixisenatide combination checked?
Interactions in our licensed database are recorded against drug classes. Lixisenatide is filed under 1 classification, and Barley has documented interactions with 1 drug class — none of Lixisenatide'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 Barley interact with any other medications?
Yes. Barley has 1 documented drug interaction in our database — Lixisenatide 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 Lixisenatide interact with any supplements?
Yes. Lixisenatide has documented interactions with 239 supplements in our database — Barley is not one of them. The Lixisenatide interaction page linked on this page lists every one, ranked by severity.
