Phlorizin 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 Phlorizin interacts with.

Phlorizin is a potent, nonselective inhibitor of SGLT1 and SGLT2. It has been shown to reduce blood glucose levels in animal research. Theoretically, phlorizin might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. However, the likelihood of this effect is unclear due to the poor bioavailability and rapid degradation of phlorizin. 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 explains PharmD, Clinical Pharmacist

Here's an interesting overlap worth knowing about. Your Canagliflozin (Invokana) lowers blood sugar by blocking SGLT2 in the kidneys, so extra sugar leaves through your urine. Phlorizin does something very similar, it blocks those same SGLT transporters. So you'd essentially be stacking two things that work the same way, which in theory could push your blood sugar lower than expected and raise the risk of hypoglycemia (shakiness, sweating, dizziness, confusion). It might also add to side effects like urinary or yeast infections and dehydration.

That said, this concern is mostly theoretical. Phlorizin is poorly absorbed when swallowed and breaks down quickly, so how much really reaches your system is unclear. Still, I'd skip mixing them without telling your pharmacist or doctor, and keep an eye on your sugar readings.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

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 Phlorizin

What is Phlorizin?

  • Blood sugar support
  • Diabetes research
  • Antioxidant
  • Weight management interest

Phlorizin is a natural plant compound (a dihydrochalcone) found in apple tree bark and other plants that has been studied mostly in the laboratory for its effects on blood sugar handling. There is no good human evidence that taking it as a supplement is safe or effective, and it is poorly absorbed when swallowed. Talk with your pharmacist or doctor before using any product containing it.

About Canagliflozin

What Is Canagliflozin Used For?

Brand name: Invokana

Invokana (canagliflozin) is used alongside diet and exercise to improve blood sugar control in adults and children aged 10 and older with type 2 diabetes. It is not for type 1 diabetes.

In adults with type 2 diabetes, Invokana is also used to lower the risk of heart attack, stroke, and cardiovascular death in those with established cardiovascular disease, and to reduce the risk of serious kidney complications — including end-stage kidney disease, cardiovascular death, and hospitalization for heart failure — in those with diabetic kidney disease and high levels of protein in the urine.
