Rosemary and Insulin Glulisine (rDNA)

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Glulisine (rDNA)

Insulin Glulisine (rDNA) falls under ANTIDIABETES DRUGS — the group Rosemary interacts with.

Theoretically, taking rosemary with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that rosemary extract can decrease blood glucose levels in diabetic models. However, research in humans is conflicting. Although rosemary powder decreased blood glucose levels in healthy adults, no change in blood glucose levels was seen in adults with type 2 diabetes, most of whom were taking 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 simple version: Apidra (insulin glulisine) already lowers your blood sugar fast, and there's a thought that rosemary, in concentrated supplement form, might nudge your sugar down a little further. If both work in the same direction at the same time, you could see low blood sugar more easily, with signs like shakiness, sweating, a racing heart, confusion, or feeling lightheaded.

I want to keep this in perspective, though. This is mostly theoretical and based on animal work plus mixed human results. In people with type 2 diabetes, rosemary didn't really change blood sugar. Rosemary as a cooking herb is not a concern. If you're considering a rosemary supplement, just check with your pharmacist or doctor first and keep an eye on your glucose readings.

“Apidra (insulin glulisine) is a rapid mealtime insulin, and this list calls for real vigilance. All 239 ingredients on file affect blood sugar, most of the 208 moderate entries by adding their own glucose lowering to the insulin's and raising the chance of a serious low.”

About Rosemary

What is Rosemary?

Rosemary
  • Memory and concentration
  • Digestive upset
  • Hair growth
  • Anxiety and stress (aromatherapy)
  • Muscle and joint discomfort
  • Antioxidant support

Rosemary is a fragrant Mediterranean herb that is safe and flavorful in normal food amounts. Some early research suggests possible benefits for memory, mood, and hair growth, but the evidence is limited and far from conclusive. Concentrated supplements and the essential oil should be used carefully, and the essential oil should never be swallowed.
