We found no known interaction between Indole-3-carbinol and Lixisenatide in our sources.

Indole-3-carbinol 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 Indole-3-carbinol 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.

Indole-3-carbinol safety at a glance

Indole-3-carbinol overall Use caution Likely fine in food amounts, but supplement doses are less studied and should be used cautiously.
Pregnancy Avoid Not enough safety data and possible hormone effects, so concentrated supplements should be avoided.
Breastfeeding Avoid Safety has not been established, so supplement use is not recommended while breastfeeding.

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

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. Indole-3-carbinol has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and estrogens (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 Indole-3-carbinol Itself Has Been Linked To

This is not an interaction — nothing below involves Lixisenatide. It is the side-effect record for Indole-3-carbinol on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Indole-3-carbinol, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on Additional detail

    “Indole-3-carbinol has been associated with reports of unsteadiness and imbalance, especially at higher doses. An adult male taking 400 mg twice daily for treatment of recurrent respiratory papillomatosis developed imbalance and tremor after 10 days of treatment. This resolved when the dose was halved.”

Everything above comes from the Natural Medicines adverse-effect record for Indole-3-carbinol — expand a row for the licensed statement it rests on. We haven’t matched Lixisenatide to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Lixisenatide.

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 Indole-3-carbinol

What is Indole-3-carbinol?

  • Estrogen and hormone balance support
  • Breast and cervical health
  • Prostate health
  • Antioxidant and 'detox' support
  • General cancer-prevention interest

Indole-3-carbinol (I3C) is a compound formed when you eat cruciferous vegetables like broccoli and cabbage, and it is sold as a supplement mainly for hormone-related and cell-protective effects. Most human evidence is preliminary or comes from lab and animal studies, so it should not be relied on to prevent or treat any disease. Talk to your pharmacist or doctor before using it, and avoid it in pregnancy and breastfeeding.

Brassicaceae · Derived from glucosinolates found in cruciferous vegetables (broccoli, cabbage, Brussels sprouts, cauliflower) · Capsules, tablets, softgels; sometimes combined with or compared to diindolylmethane (DIM)

An interaction check asks whether these two react with each other — it does not ask whether Indole-3-carbinol is a good idea for someone in your situation. Here is what our Indole-3-carbinol record says about it on its own.

Indole-3-carbinol: dosing

There is no officially established or standardized dose for I3C. Different products and studies have used different amounts, and there is no agreed-upon 'best' dose.The safest approach is to follow the directions on the product label and not exceed them. They can help you decide whether I3C is appropriate for you.

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.
