Hollyhock and Acetohexamide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Acetohexamide

Acetohexamide falls under ANTIDIABETES DRUGS — the group Hollyhock interacts with.

Animal and in vitro research shows that hollyhock flower extracts might lower blood glucose levels. While the effect of hollyhock in patients with diabetes has not been studied, theoretically, hollyhock might decrease blood glucose and have additive effects in patients treated with antidiabetes drugs. Dose adjustments to diabetes medications may be necessarily. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.
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 explains PharmD, Clinical Pharmacist

Acetohexamide is an older sulfonylurea that lowers your blood sugar by nudging your pancreas to release more insulin. Here's the wrinkle with hollyhock: in lab and animal studies, hollyhock flower extracts seemed to push blood sugar down too. So if you took both, their effects could stack and your blood sugar might drop lower than you expect.

I'll be honest, this is a theoretical concern. We don't have real human studies on hollyhock in people with diabetes, so it's more a caution than a proven problem. Still, watch for signs of low blood sugar like shakiness, sweating, dizziness, or confusion, especially with concentrated supplement doses rather than an occasional tea. Please check with your pharmacist or doctor before adding it so they can watch your numbers.

“Acetohexamide (Dymelor) is an older sulfonylurea, a pill with one job, pulling blood sugar down, so anything else that lowers glucose stacks on top of it. That is what most of this list does.”

About Hollyhock

What is Hollyhock?

  • Sore throat and cough
  • Digestive upset
  • Soothing irritated skin
  • Mild inflammation
  • Urinary discomfort

Hollyhock is a flowering plant in the mallow family that has been used in traditional medicine, mainly as a soothing (demulcent) remedy for the throat, gut, and skin. Solid human studies are very limited, so its benefits are not well proven. It is generally considered gentle, but you should still talk to a pharmacist or doctor before using it, especially if you are pregnant or breastfeeding.
