Brewer's Yeast and Alogliptin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Alogliptin

Alogliptin falls under ANTIDIABETES DRUGS — the group Brewer's Yeast interacts with.

Taking brewer's yeast with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking chromium-containing brewer's yeast can decrease levels of blood glucose in diabetic patients being treated with antidiabetes drugs.
Severity Moderate Likelihood Possible Evidence B

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 for alogliptin (Nesina): brewer's yeast naturally contains chromium, and some studies suggest chromium can give your blood sugar a little extra nudge downward. Pair that with a diabetes medicine like alogliptin and the two may add up, so your blood sugar could dip lower than expected.

Alogliptin by itself rarely causes true lows, but if your sugar does drop you might feel shaky, sweaty, dizzy, or unusually tired. This is a moderate, possible interaction backed by some patient research, not a guaranteed problem. A little brewer's yeast in food is unlikely to matter much, but if you take it as a regular supplement, check in with your pharmacist or doctor and keep an eye on your readings.
