Dill and Glipizide, Metformin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Glipizide, Metformin

Glipizide, Metformin falls under ANTIDIABETES DRUGS — the group Dill interacts with.

Theoretically, dill extract might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Animal research shows that dill extract can reduce blood sugar levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
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

This combo pill pairs glipizide (which nudges your pancreas to release more insulin) with metformin (which lowers the sugar your liver makes). Both already work to bring your blood sugar down. The thinking here is that concentrated dill might add a small extra sugar-lowering push, so the two together could occasionally drop your levels a little too far.

Honestly, this is theoretical and based only on animal studies, so I wouldn't lose sleep over it. The dill in your pickles or salad won't matter. With concentrated dill supplements or dill oil, just keep an eye out for low-sugar signs (shakiness, sweating, dizziness) and check your readings. Glipizide is the part most likely to cause a true low. Chat with your pharmacist or doctor before adding any dill supplement.

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

“Glipizide and metformin (Metaglip) already work hard to pull blood sugar down, which is exactly why this list of 307 ingredients deserves genuine vigilance rather than a shrug. Most of them, 239, can lower glucose on their own, and stacked on this pill the combined effect can tip into true hypoglycemia.”
