Dragon Fruit and Acarbose

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Acarbose

Acarbose falls under ANTIDIABETES DRUGS — the group Dragon Fruit interacts with.

Dragon fruit might lower blood glucose levels. Theoretically, it might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Dose adjustments to diabetes medications might be necessary.
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 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 simple version: dragon fruit may nudge your blood sugar down a little on its own, mostly thanks to its fiber and plant compounds. Since acarbose already works by slowing how fast sugar gets absorbed after meals, adding dragon fruit could add to that effect and make your numbers run lower than expected.

The good news is that this is based on fairly weak evidence, and acarbose by itself rarely causes low blood sugar. The bigger thing to watch is if you also take insulin or a sulfonylurea, where lows are more likely. Enjoying dragon fruit as a normal food is usually fine. If you're using concentrated extracts or notice shakiness, sweating, or dizziness, check your sugar and talk with your pharmacist or doctor before changing anything.

About Dragon Fruit
