Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Avoid combining berberine with Januvia without medical supervision. If use is desired, frequent glucose monitoring is essential. Dose adjustment of Januvia may be required.
Why this interaction occurs
Berberine activates AMPK, inhibits DPP-4 (same target as sitagliptin), and improves insulin sensitivity — mechanisms that directly overlap with Januvia. Concurrent use can cause significant additive blood glucose lowering and increase hypoglycemia risk.
Evidence
Evidence level: moderate.
Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 62,404 reports mentioning Januvia. This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the Januvia + supplement combination on this page.
FAERS reports are voluntary and cannot prove that a drug caused an event. Do not use report counts to assess the safety of this specific drug-supplement pair.
