Jequirity and Nateglinide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Nateglinide

Nateglinide falls under ANTIDIABETES DRUGS — the group Jequirity interacts with.

Evidence from animal research suggests that an extract of jequirity can reduce blood glucose levels. Theoretically, jequirity might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments might 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 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

First, the most important thing here has nothing to do with blood sugar: jequirity seeds contain abrin, a toxin so dangerous it can be deadly in tiny amounts. I would not use this plant as a supplement at all, full stop.

Now, about the blood sugar piece. In animal studies, jequirity extract seemed to lower blood glucose. Nateglinide already lowers your blood sugar by nudging your pancreas to release insulin, so in theory the two together could push it down too far. That can mean hypoglycemia: shakiness, sweating, dizziness, confusion, or a racing heart. Keep in mind this concern is theoretical and based only on animal research, not strong human data. Please talk with your pharmacist or doctor before mixing anything new with Starlix.

From our pharmacist’s overview on the Nateglinide page

“People who take nateglinide (Starlix) with meals for type 2 diabetes are often drawn to supplements marketed for blood sugar, and that overlap is why these 290 interactions warrant real caution. Some 239 of the ingredients affect blood sugar on their own, most pushing it lower, so stacking them on nateglinide raises the odds of hypogly…”

Jequirity (Abrus precatorius) is a tropical plant whose bright red, black-tipped seeds contain abrin, one of the most toxic plant proteins known. Despite a long history in traditional medicine, the seeds are dangerously poisonous and there is no reliable evidence that it is safe or effective. It should not be used as a supplement or medicine.
