Neem and Insulin Glargine, Lixisenatide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Glargine, Lixisenatide

Insulin Glargine, Lixisenatide falls under ANTIDIABETES DRUGS — the group Neem interacts with.

Neem might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Some clinical research shows that neem can lower blood glucose levels in adults with type 2 diabetes, including those already taking metformin.
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 simple version: Soliqua already does a strong job of lowering your blood sugar. It combines a long-acting insulin (glargine) with lixisenatide, which boosts your body's own insulin after meals. Neem may push blood sugar down a little more on its own, so stacking the two could add up and leave you running too low.

If your sugar drops too far, you might feel shaky, sweaty, dizzy, confused, or very hungry. The good news is the evidence here is on the weaker side, mostly lab and small human studies, so this isn't a guaranteed problem. Still, if you want to try neem, check with your pharmacist or doctor first and keep an eye on your glucose readings. Don't change your Soliqua dose on your own.

“Soliqua 100/33 pairs a long-acting insulin, glargine, with lixisenatide, so its whole job is pushing blood sugar down, and that is also what most of the 242 supplements and herbs on this list do. The overlap earns real caution here.”

About Neem

What is Neem?

Neem
  • Skin conditions
  • Dental and gum health
  • Antimicrobial and antiparasitic
  • Digestive upset
  • Blood sugar support
  • Insect repellent/pesticide

Neem is a tree from India used for centuries in traditional medicine, especially for skin, dental, and antimicrobial purposes. Some small studies are promising for oral health and skin, but high-quality human evidence is limited for most uses. Neem oil and seed extracts can be toxic if swallowed, especially in children, so use with caution and talk to your pharmacist or doctor first.
