Anise 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 Anise interacts with.

Theoretically, anise seed might increase the risk of hypoglycemia when taken with antidiabetes drugs.
A small clinical study shows that anise seed powder decreases fasting blood glucose levels by 36% when compared to baseline.
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: Apidra (insulin glulisine) is a fast-acting insulin that lowers your blood sugar after meals. Anise seed may have its own mild blood-sugar-lowering effect. One small study found anise powder dropped fasting glucose by about 36 percent. So if you regularly take concentrated anise on top of your insulin, the two could add up and push your sugar too low.

Watch for hypoglycemia signs like shakiness, sweating, a racing heart, confusion, or feeling lightheaded. The occasional anise tea or a sprinkle in cooking is unlikely to cause trouble, but a daily supplement dose is worth a conversation. Don't change your insulin on your own. Check with your pharmacist or doctor, and keep monitoring your blood sugar closely.

About Anise

What is Anise?

Anise
  • Digestive upset and bloating
  • Cough and respiratory complaints
  • Sore throat
  • Menstrual discomfort
  • Flavoring agent

Anise is a fragrant, licorice-flavored seed used for centuries to ease digestion and soothe coughs. Most of its health claims are based on tradition and small or laboratory studies rather than strong human research, so evidence is limited. It is generally safe as a food and tea for most adults, but the concentrated essential oil should be used carefully and avoided in pregnancy.
