Miracle Fruit and Repaglinide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Repaglinide

Repaglinide falls under ANTIDIABETES DRUGS — the group Miracle Fruit interacts with.

Theoretically, miracle fruit leaf might have an additive effect with antidiabetes drugs and increase the risk of hypoglycemia. Evidence from an animal model shows that miracle fruit leaf increases insulin production and lowers fasting blood glucose and HbA1c in rats with streptozotocin-induced diabetes. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), 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

Here's the gist: repaglinide already works by nudging your pancreas to release more insulin, which brings your blood sugar down. The concern with miracle fruit is that concentrated miracle fruit leaf may do something similar, lowering blood sugar on its own. Stack the two together and the effects could pile up, raising your odds of hypoglycemia (low blood sugar). That can show up as shakiness, sweating, dizziness, a racing heart, confusion, or feeling unusually hungry.

That said, I want to keep this in perspective. This warning comes only from a rat study, so it's theoretical for people. Enjoying the berry occasionally to sweeten sour foods is very unlikely to be the problem. If you're thinking about regular leaf extract supplements, check with your pharmacist or doctor first and keep monitoring your sugars.

From our pharmacist’s overview on the Repaglinide page

“Repaglinide (Prandin, GlucoNorm) is taken right before meals to drop blood sugar quickly, and that speed is exactly why this list deserves real respect.

About Repaglinide

What Is Repaglinide Used For?

Brand names: Prandin, GlucoNorm

Repaglinide tablets are used to help control blood sugar in adults with type 2 diabetes, together with diet and exercise. It is not a substitute for healthy habits — it works best as part of a full diabetes management plan.

Repaglinide is not for type 1 diabetes or for treating diabetic ketoacidosis (a dangerous condition where the blood becomes too acidic due to lack of insulin).
