Interaction report

Shark Cartilage 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 Shark Cartilage 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.

Shark Cartilage safety at a glance

Shark Cartilage overall Use caution Often poorly studied, may cause digestive upset, and proven benefits are lacking.

Breastfeeding Avoid Not enough safety data; avoid 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. Shark Cartilage has documented interactions with 1 drug class — the most serious being immunosuppressants (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.

See Every Supplement That Interacts With Lixisenatide

This page covers Shark Cartilage only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lixisenatide page lists 239 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate), Agaricus Mushroom (moderate) and Agmatine (moderate).

By severity: 1 major · 208 moderate · 30 minor.

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 Shark Cartilage

What is Shark Cartilage?

  • Cancer support (popular use)
  • Arthritis and joint pain
  • Psoriasis
  • Wound healing
  • General immune support

Shark cartilage is a supplement made from the skeletal tissue of sharks that was heavily promoted for cancer and joint conditions, but good-quality clinical trials have not shown meaningful benefit. It is generally not recommended, and there are real environmental and safety concerns, so talk with your doctor or pharmacist before considering it.

Cartilage (skeletal tissue) from sharks, often from species such as the spiny dogfish and hammerhead · Capsules, tablets, powder

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

Shark Cartilage: dosing

There is no established or standardized dose for shark cartilage, and products vary widely in their content and quality. Studies have used very different amounts and forms, so no reliable recommended dose exists.If you are considering shark cartilage despite the limited evidence, follow the directions on the product label and do not exceed them.

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.
