Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Coleus and Lixisenatide 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.

Coleus 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 Coleus 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.

Coleus safety at a glance

Coleus overall Use caution May lower blood pressure and is not well studied for long-term use, so use with care and professional guidance.
Pregnancy Possibly Unsafe When used orally. Evidence from animal research suggests that high doses of coleus can inhibit embryo implantation and/or delay fetal development; avoid using. Read the full pregnancy detail
Breastfeeding Avoid Not enough safety data; avoid use while breastfeeding.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. 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. Coleus has documented interactions with 7 drug classes — the most serious being calcium channel blockers (major), nitrates (major) and anticoagulant/antiplatelet drugs (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.

Keep it in perspective

Coleus Does Interact With Other Medications

What to actually watch for

What Coleus Itself Has Been Linked To

This is not an interaction — nothing below involves Lixisenatide. It is the side-effect record for Coleus on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Coleus, this list is the first place to look.

  • Eye irritation or redness / Tremor or shakiness / Anxiety or restlessness Additional detail

    “Orally, intravenously, ophthalmologically, and by inhalation, coleus seems to be well tolerated.

    Most Common Adverse Effects:

    Orally: Constipation, diarrhea, nausea, vomiting.

    Intravenously: Flushing, hypotension, tachycardia.

    Ophthalmologically: Conjunctival hyperemia, stinging eyes.

    Inhalation: Irritation of the respiratory tract, restlessness, tremor.”

  • Flushing / A fast or pounding heartbeat / Low blood pressure Additional detail

    “Intravenously, the coleus constituent, forskolin, can cause tachycardia, flushing and hypotension.”

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 Coleus

What is Coleus?

Coleus
  • Weight management
  • Asthma and breathing
  • High blood pressure
  • Heart conditions
  • Glaucoma (eye pressure)
  • Exercise and body composition

Coleus is a plant from the mint family whose root contains a compound called forskolin, often marketed for weight loss, asthma, and heart health. While early lab and small human studies are interesting, solid proof that Coleus supplements help any of these conditions is limited. Talk to your pharmacist or doctor before using it, especially if you have heart problems or low blood pressure.

Coleus forskohlii · Lamiaceae · Roots (source of forskolin) · Capsules, tablets, standardized extracts (often standardized to forskolin), powders

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

Coleus: dosing

There is no official, well-established dose for Coleus. Products vary widely in strength and are often standardized to a certain percentage of forskolin, but the best dose for any health goal has not been proven.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

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 Coleus and Lixisenatide Together: Common Questions

Is it safe to take Coleus with Lixisenatide?

Lixisenatide is filed under 1 classification, and Coleus has documented interactions with 7 drug classes — 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.
