Interaction report

Fo-ti and Acetohexamide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Fo-ti interacts with whole categories of medication. Acetohexamide falls into 2 of those categories, so it can interact with Fo-ti in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

HEPATOTOXIC DRUGS

1 of 2

Why this applies to Acetohexamide

Acetohexamide falls under HEPATOTOXIC DRUGS — the group Fo-ti interacts with.

Theoretically, fo-ti might increase the risk of liver damage when taken with hepatotoxic drugs.
Fo-ti has been linked to liver damage in many reports.
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

Here's the concern with pairing Fo-ti and acetohexamide (Dymelor), an older sulfonylurea pill used to lower blood sugar in type 2 diabetes. This isn't about Fo-ti changing your sugar levels directly. The issue is the liver. Processed Fo-ti has shown up in a number of case reports linked to liver injury, and acetohexamide itself can occasionally stress the liver. Stacking two things that can both be tough on the liver may raise that risk.

To be fair, this is theoretical and based mostly on scattered anecdotal reports, not strong studies, so I don't want to alarm you. Still, watch for warning signs like yellowing eyes or skin, dark urine, belly pain, or unusual tiredness. Please loop in your pharmacist or doctor before combining them.

ANTIDIABETES DRUGS

2 of 2

Acetohexamide also falls under ANTIDIABETES DRUGS.

Theoretically, fo-ti might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Fo-ti reportedly has hypoglycemic effects.
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 short version: acetohexamide (Dymelor) is an older sulfonylurea that lowers blood sugar by nudging your pancreas to release more insulin. Fo-ti has been reported to have its own mild blood-sugar-lowering effect. So when you combine the two, the worry is simple addition, meaning your sugar could drop lower than expected.

If that happens, you might feel shaky, sweaty, dizzy, irritable, or get a pounding heart, the usual signs of low blood sugar (hypoglycemia). I want to be honest though, this concern is theoretical, based on how these things work rather than solid human studies, so don't panic. Please don't stop or change either one on your own. Just check with your pharmacist or doctor, and keep an eye on your home glucose 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.”
