Dill and Insulin Glargine

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Glargine

Insulin Glargine 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

Here's the gist: insulin glargine already does the heavy lifting of lowering your blood sugar. Dill, at least in animal studies, seems to nudge blood sugar down a little too. So if you pair concentrated dill supplements with your insulin, the two could stack up and push your sugar lower than you intend. That raises the odds of a low blood sugar episode, with symptoms like shakiness, sweating, dizziness, a racing heart, or feeling confused.

I want to be honest about the strength of this, though. The evidence is theoretical and comes from lab and animal research, not solid human studies. Normal cooking amounts of dill in your food are very unlikely to cause trouble. If you're thinking about a dill supplement or oil, check your glucose more closely and run it by your pharmacist or doctor first.
