Blueberry and Acetohexamide

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

Minor

ANTIDIABETES DRUGS

Why this applies to Acetohexamide

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

Theoretically, blueberries or blueberry leaf extracts might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggests that blueberry and/or blueberry leaf extracts can lower blood glucose levels.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Acetohexamide (Dymelor) is an older sulfonylurea that works by pushing your pancreas to release more insulin, which lowers your blood sugar. The concern here is simple math: if blueberry extracts also nudge your blood sugar down, the two together could potentially drop it a little lower than expected. That might show up as shakiness, sweating, hunger, dizziness, or feeling lightheaded, the usual signs of low blood sugar (hypoglycemia).

That said, I want to keep this in perspective. This is a theoretical flag based only on lab and animal studies, and it's rated minor and unlikely. Eating blueberries as food is not a worry. Concentrated blueberry leaf extracts are the bigger unknown. If you'd like to try one, check with your pharmacist or doctor first and keep an eye on your sugar readings.

From our pharmacist’s overview on the Acetohexamide page

“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 Blueberry

What is Blueberry?

  • Antioxidant support
  • Heart health
  • Brain and memory health
  • Blood sugar support
  • Eye health
  • Urinary health

Blueberries are a nutritious fruit rich in antioxidants called anthocyanins, and eating them as part of a balanced diet is healthy and safe for most people. Concentrated supplements are marketed for heart, brain, and blood sugar health, but the evidence is mostly early and not strong enough to promise specific benefits. Enjoy blueberries as food, and talk to your pharmacist before using high-dose extracts.
