Dragon Fruit and Canagliflozin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Canagliflozin

Canagliflozin 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. Since canagliflozin (Invokana) is already working to lower your blood sugar by helping your kidneys flush out extra glucose, eating a lot of dragon fruit could, in theory, add to that effect. For some folks that might mean blood sugar dips lower than expected.

The good news is that the evidence here is on the weaker side and the concern is mostly theoretical. Enjoying dragon fruit as a normal food is very unlikely to cause trouble. Concentrated extracts or large amounts are where I'd be a bit more careful. Canagliflozin alone rarely causes lows, but if you also take insulin or a sulfonylurea, watch for shakiness, sweating, or dizziness, and check with your pharmacist.

From our pharmacist’s overview on the Canagliflozin page

“Canagliflozin (Invokana) lowers blood sugar, and that is precisely why this list deserves genuine care. Nearly every ingredient on it works on glucose one way or another: most can push it too low when stacked with the drug, while a few, niacin among them, raise it and work against the medicine.”

About Dragon Fruit

What is Dragon Fruit?

Dragon fruit is a colorful tropical fruit that is a nutritious, low-calorie source of fiber, vitamin C, and antioxidants.
