Radish and Alogliptin, Metformin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Alogliptin, Metformin

Alogliptin, Metformin falls under ANTIDIABETES DRUGS — the group Radish interacts with.

Theoretically, radish might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that radish extract, juice, and sprouts can reduce glucose levels. Animal research also shows that radish root juice 300 mg/kg reduces fasting and postprandial blood glucose in a rat model of diabetes, with effects similar to glibenclamide.
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 simple version: Kazano combines two diabetes medicines (alogliptin and metformin) that already work to lower your blood sugar. Radish, in some animal studies, also seemed to nudge blood sugar down a bit. So the theoretical worry is that stacking the two could push your sugar a little too low, what we call hypoglycemia. Signs to know are shakiness, sweating, dizziness, confusion, or feeling unusually hungry.

Now, the honest part: this caution comes from lab and animal research, not solid human studies, so the real-world risk is probably small. Enjoying radishes in your meals is generally fine. If you're thinking about a concentrated radish supplement, just run it by your pharmacist or doctor first, and keep an eye on your home glucose readings.

From our pharmacist’s overview on the Alogliptin, Metformin page

“Kazano combines alogliptin and metformin to lower blood sugar, and nearly everything on this list pushes on that same lever, so I treat these pairings with real caution. Most entries are herbs and supplements that lower glucose on their own, and stacked on the drug they raise the risk of hypoglycemia, a sugar drop steep enough to cause…”

About Radish

What is Radish?

  • Digestive support
  • Liver and gallbladder health
  • Antioxidant support
  • Respiratory and cough relief
  • General nutrition

Radish is a common edible root vegetable that is nutritious and generally safe to eat as food. Some people use radish (especially black radish) and its extracts for digestion and liver support, but high-quality human evidence for supplement-level health benefits is limited. Eating radish as part of a normal diet is fine for most people; talk to your pharmacist or doctor before using concentrated supplements.
