Kudzu and Insulin Lispro Recombinant

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

Minor

ANTIDIABETES DRUGS

Why this applies to Insulin Lispro Recombinant

Insulin Lispro Recombinant falls under ANTIDIABETES DRUGS — the group Kudzu interacts with.

Theoretically, taking kudzu with antidiabetes drugs might increase the risk of hypoglycemia.
Kudzu might lower blood glucose levels and have additive effects in patients treated with antidiabetic agents. The dose of diabetes medications might need to be adjusted.
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

Here's the simple version: Humalog (insulin lispro) is a fast-acting insulin that lowers your blood sugar after meals. Kudzu, mostly in concentrated supplement form, may nudge blood sugar down a bit on its own. Put the two together and the worry is that they add up, pushing your sugar lower than you intended.

If that happened, you might notice the usual signs of low blood sugar (hypoglycemia): shakiness, sweating, a fast heartbeat, dizziness, or feeling confused. I want to be honest, though, this concern comes only from lab and animal research, and it's rated as minor and unlikely. Still, since insulin is powerful and dosed carefully, it's worth a quick chat with your pharmacist or doctor before adding kudzu, and keep an eye on your glucose readings if you do.

See Every Supplement That Interacts With Insulin Lispro Recombinant

This page covers Kudzu only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Insulin Lispro Recombinant page lists 242 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Chelation Therapy Products (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 211 moderate · 29 minor.

From our pharmacist’s overview on the Insulin Lispro Recombinant page

“Two of the 242 entries here rate major, and they are the place to start. Siberian cocklebur has caused severe hypoglycemia, and chelation products containing EDTA can drop blood glucose steeply while also interfering with the insulin itself, so neither belongs anywhere near insulin lispro (Humalog KwikPen).”

Kudzu is a fast-growing vine whose root has long been used in traditional Chinese medicine and is now studied mostly for reducing alcohol intake.
