Capers 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 Capers interacts with.

Some preliminary clinical research shows that taking caper fruit extract 1200 mg daily for 2 months can lower fasting blood glucose and glycated hemoglobin (HbA1c) in patients with type 2 diabetes who are already taking antidiabetes drugs. However, other research does not support this effect. Until more is known, monitor blood glucose levels closely. Medication dose adjustments may be necessary.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
Severity Moderate Likelihood Possible Evidence B

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 practical takeaway: acetohexamide (Dymelor) is an older sulfonylurea that lowers your blood sugar by nudging your pancreas to release more insulin. Some early research suggests concentrated caper fruit extract (around 1200 mg a day) may also bring blood sugar down a bit. So if you pair the two, those effects can stack, and your blood sugar could drop lower than expected.

When blood sugar runs too low with this drug, you might feel shaky, sweaty, dizzy, hungry, or confused. The evidence here is fairly weak and not consistent, and everyday cooking amounts of capers are very unlikely to cause trouble. Still, if you're considering a caper supplement, check your numbers more closely and talk with your pharmacist or doctor before changing anything.

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 Capers

What is Capers?

  • Digestive support
  • Antioxidant source
  • Blood sugar support
  • Anti-inflammatory
  • Skin and traditional tonic uses

Capers are the edible pickled flower buds of the Capparis spinosa shrub, used widely as food and in traditional medicine. They contain antioxidant plant compounds, but high-quality human studies on health benefits are limited, so the supplement claims remain largely unproven. As a food, capers are generally safe, but talk to your pharmacist or doctor before using concentrated extracts.
