Stevia and Insulin Lispro

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

Minor

ANTIDIABETES DRUGS

Why this applies to Insulin Lispro

Insulin Lispro falls under ANTIDIABETES DRUGS — the group Stevia interacts with.

Theoretically, stevia might increase the risk for hypoglycemia when combined with antidiabetes drugs.
Preliminary clinical research in patients with type 2 diabetes suggests that taking a single dose of stevia extract 1000 mg reduces postprandial blood glucose levels when taken with a meal. However, other clinical research in patients with type 1 or type 2 diabetes suggests that taking stevioside 250 mg three times daily does not significantly affect blood glucose levels or glycated hemoglobin (HbA1C) after three months of treatment.
Severity Minor 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 for anyone using insulin lispro (like Admelog) alongside stevia. The concern is mostly theoretical: some early studies hint that stevia might nudge blood sugar down a little, especially after meals. If that happens while you're already dosing insulin lispro, the two could add up and push your sugar lower than expected, raising the chance of a low blood sugar (hypoglycemia) episode. Think shakiness, sweating, dizziness, confusion, or a fast heartbeat.

That said, the evidence is thin, and other studies found no real change in blood sugar or A1C over time. Sweetener-sized amounts of stevia in your coffee or food are very unlikely to matter. If you plan to take concentrated stevia supplements, just give your pharmacist or doctor a heads-up so they can keep an eye on your numbers.

From our pharmacist’s overview on the Insulin Lispro page

“Blood sugar is the entire subject of this list. Insulin lispro (Admelog) is a rapid mealtime insulin dosed to bring glucose down after eating, and the supplements below can shove that same number around, most of them downward, which risks a genuine low.”

About Stevia

What is Stevia?

  • Sugar substitute / sweetener

  • Blood pressure support
  • Reducing calorie intake

Stevia is a plant-based, calorie-free sweetener that is widely used as a sugar alternative and is considered safe in normal food amounts by major regulators. Purified stevia extracts have a good safety record, but evidence for medicinal benefits like lowering blood sugar or blood pressure is limited. Talk to your pharmacist or doctor before using stevia supplements for any health condition.

About Insulin Lispro Injection

What Is Insulin Lispro Injection Used For?

Brand names: Admelog, Admelog Solostar

Insulin lispro injection is used to improve glycemic control (blood sugar management) in people with diabetes mellitus. It is a rapid-acting insulin analog approved for use in both type 1 and type 2 diabetes.

Admelog is specifically indicated to improve glycemic control in patients with diabetes mellitus. Humalog Mix75/25 is indicated to improve glycemic control in adults with diabetes mellitus; it is a fixed-ratio mixture of insulin lispro and insulin lispro protamine, and its fixed proportions do not allow for separate adjustment of basal (background) and prandial (mealtime) doses.
