Phlorizin and Insulin Lispro Recombinant

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Lispro Recombinant

Insulin Lispro Recombinant 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 the simple version: Humalog (insulin lispro) is a fast-acting insulin you take to bring your blood sugar down around meals. Phlorizin works in a totally different way, pushing extra sugar out through your urine, which also tends to lower blood sugar. Stack two blood-sugar-lowering effects on top of each other and you could end up lower than you intended.

If that happens, you might notice shakiness, sweating, a racing heart, confusion, or feeling lightheaded, the usual signs of hypoglycemia. That said, this is a theoretical concern. Phlorizin is poorly absorbed when swallowed and breaks down quickly, so a real-world effect is far from certain. Still, since insulin leaves little room for error, please check with your pharmacist or doctor before combining them, and keep an eye on your glucose 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.

See Every Supplement That Interacts With Insulin Lispro Recombinant

This page covers Phlorizin only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Insulin Lispro Recombinant page lists 242 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Chelation Therapy Products (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 211 moderate · 29 minor.

From our pharmacist’s overview on the Insulin Lispro Recombinant page

“Two of the 242 entries here rate major, and they are the place to start. Siberian cocklebur has caused severe hypoglycemia, and chelation products containing EDTA can drop blood glucose steeply while also interfering with the insulin itself, so neither belongs anywhere near insulin lispro (Humalog KwikPen).”

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.
