Oregon Grape and Albiglutide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Albiglutide

Albiglutide falls under ANTIDIABETES DRUGS — the group Oregon Grape interacts with.

Theoretically, Oregon grape might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research suggests that berberine, a constituent of Oregon grape, can lower blood glucose levels.
Severity Moderate Likelihood Possible Evidence A

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 thing to keep in mind with this pair. Albiglutide (Tanzeum) is an injectable medicine that helps your pancreas release insulin and brings blood sugar down. Oregon grape contains berberine, and research shows berberine can also lower blood sugar on its own. So you're stacking two things that push glucose in the same direction.

Taken together, your blood sugar could drop lower than expected. Watch for signs of low blood sugar, like shakiness, sweating, dizziness, headache, or feeling confused or unusually hungry. This isn't a reason to panic, and food amounts aren't the concern here, concentrated supplement doses are. Please loop in your pharmacist or doctor before adding Oregon grape, since they may want to check your sugars or adjust things. Don't stop your albiglutide on your own.

From our pharmacist’s overview on the Albiglutide page

“People injecting albiglutide (Tanzeum) once a week for type 2 diabetes are often the same people eyeing supplements marketed for blood sugar, and that overlap is exactly where this list calls for real vigilance. Every one of the 239 ingredients on file touches glucose control in some way, most by adding to albiglutide's glucose-lowerin…”
