Ambrette and Metformin, Sitagliptin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Metformin, Sitagliptin

Metformin, Sitagliptin falls under ANTIDIABETES DRUGS — the group Ambrette interacts with.

Theoretically, concomitant use of ambrette with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that myricetin, a constituent of ambrette, can lower blood glucose levels.
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 gist with Janumet, which is the combo of metformin and sitagliptin. One plant compound found in ambrette, called myricetin, has lowered blood sugar in animal studies. Since Janumet already works to bring your blood sugar down, layering ambrette on top could, in theory, push it a little too low.

If that happened, you might feel shaky, sweaty, dizzy, lightheaded, or unusually hungry. I want to be honest, though: this is a theoretical concern based on lab and animal data, not real-world human reports, so the actual risk looks low. If you'd like to try ambrette, just give me or your doctor a heads-up first, and keep an eye on your home glucose readings.

About Ambrette

What is Ambrette?

Ambrette
  • Fragrance and aromatherapy
  • Digestive complaints
  • Respiratory complaints
  • Skin irritation
  • Insect repellent (traditional)

Ambrette (Abelmoschus moschatus) is a fragrant plant best known for its musky seed oil used in perfumes and food flavoring. It has a long history in traditional medicine for digestion, breathing problems, and skin issues, but solid human studies supporting these uses are lacking. If you want to try it, talk with your pharmacist or doctor first, and avoid use during pregnancy and breastfeeding.
