Prickly Pear Cactus and Lixisenatide

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIDIABETES DRUGS

Why this applies to Lixisenatide

Lixisenatide falls under ANTIDIABETES DRUGS — the group Prickly Pear Cactus interacts with.

Combining prickly pear cactus with antidiabetes drugs might increase the risk of hypoglycemia.
Case reports show that combining prickly pear cactus with antidiabetes drugs such as chlorpropamide, glyburide, glipizide, and metformin can increase the risk of hypoglycemia in patients with type 2 diabetes. Advise patients to monitor glucose levels closely. Dose adjustments may be necessary.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: prickly pear cactus may gently lower your blood sugar on its own, mostly thanks to its soluble fiber slowing how fast sugar gets absorbed after a meal. Lixisenatide (Adlyxin) already works to bring your blood sugar down, so stacking the two could push your numbers lower than you want. This isn't about the cactus blocking or speeding up how your body clears the drug. It's simply two blood-sugar-lowering effects adding up.

Watch for signs of low blood sugar: shakiness, sweating, dizziness, headache, or feeling confused or extra hungry. The evidence here is mostly anecdotal (a handful of case reports), so for many people it stays mild, but it's worth checking your glucose more closely. Please don't change your lixisenatide dose on your own. Just loop in your pharmacist or doctor first.

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 Prickly Pear Cactus

What is Prickly Pear Cactus?

  • Blood sugar control
  • High cholesterol
  • Hangover symptoms
  • Digestive health
  • Antioxidant support

Prickly pear cactus is a desert plant whose pads and fruit are eaten as food and taken as a supplement, mainly for blood sugar, cholesterol, and hangover symptoms. Some small studies suggest modest benefits, but the evidence is limited and not strong enough to rely on it as a treatment. Talk with your pharmacist or doctor before using it, especially if you take medication for diabetes.

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.
