Dandelion and Glimepiride

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Glimepiride

Glimepiride falls under ANTIDIABETES DRUGS — the group Dandelion interacts with.

Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

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

Here's the gist: glimepiride already works hard to lower your blood sugar by nudging your pancreas to release more insulin. Dandelion, at least in lab studies, may have a mild blood-sugar-lowering effect of its own, possibly by slowing sugar absorption and bumping up insulin a little. Stack the two together and the worry is that your numbers could dip too low.

That said, this is mostly a theoretical concern based on lab work and a single case report, so it's not a strong or proven interaction. Food-sized amounts of dandelion in a salad are unlikely to cause trouble, but concentrated supplements are more of a question mark. Watch for shakiness, sweating, dizziness, or confusion, and check with your pharmacist or doctor before adding a dandelion supplement.

From our pharmacist’s overview on the Glimepiride page

“Glimepiride (Amaryl) is a sulfonylurea, a diabetes pill that prompts the pancreas to release insulin, so anything that further lowers blood sugar can tip you into hypoglycemia, and that describes most of this list. Of the 306 supplement and herbal ingredients on file, 239 can move blood sugar on their own.”

About Dandelion

What is Dandelion?

Dandelion
  • Water retention (diuretic)
  • Digestive upset
  • Liver and gallbladder support
  • Mild appetite stimulant
  • Skin conditions

Dandelion is a common plant used in food and traditional medicine, often promoted as a natural 'water pill' and digestive aid. Human evidence for these uses is very limited, so its benefits are not well proven. It is generally considered safe as a food, but talk to your pharmacist or doctor before using concentrated supplements, especially if you have allergies or take other medicines.

About Glimepiride

What Is Glimepiride Used For?

Brand name: Amaryl

Glimepiride tablets are used to improve blood sugar control in adults with type 2 diabetes. It is always used together with a healthy diet and regular exercise — not as a standalone treatment.

Glimepiride is not appropriate for type 1 diabetes or diabetic ketoacidosis (a serious complication where the body produces high levels of blood acids called ketones), as it would not work in those situations.
