Tinospora Cordifolia and Nateglinide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Tinospora Cordifolia interacts with whole categories of medication. Nateglinide falls into 2 of those categories, so it can interact with Tinospora Cordifolia in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

1 of 2

Why this applies to Nateglinide

Nateglinide falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Tinospora Cordifolia interacts with.

Theoretically, Tinospora cordifolia might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that Tinospora cordifolia extract inhibits CYP2C9. Animal research shows that Tinospora cordifolia extract 400 mg/kg twice daily for 14 days reduces the clearance and increases plasma levels of glyburide, a CYP2C9 substrate. However, this interaction has not been reported in humans.
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 explains PharmD, Clinical Pharmacist

Here's the basic idea with Giloy (Tinospora cordifolia) and your nateglinide. Nateglinide is cleared mostly by a liver enzyme called CYP2C9. In lab and animal studies, Giloy appears to slow that enzyme down. If that same effect happened in people, nateglinide could hang around longer and act a bit stronger than expected.

Since nateglinide already works by prompting your pancreas to release insulin, a stronger effect mainly means a higher chance of low blood sugar: shakiness, sweating, dizziness, hunger, or a fast heartbeat. To be clear, this interaction is theoretical and has not been seen in humans, so I don't want to alarm you. Still, given that Giloy has also been linked to liver injury, it's worth a quick chat with your pharmacist or doctor before combining them.

ANTIDIABETES DRUGS

2 of 2

Nateglinide also falls under ANTIDIABETES DRUGS.

Theoretically, Tinospora cordifolia might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research in adults with type 2 diabetes shows that Tinospora cordifolia can reduce fasting blood glucose and glycated hemoglobin. Additionally, animal research shows that Tinospora cordifolia has hypoglycemic effects.
Severity Moderate Likelihood Possible Evidence A

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: nateglinide (Starlix) works by nudging your pancreas to release more insulin right around mealtime, which brings your blood sugar down. Giloy (Tinospora cordifolia) appears to have its own blood-sugar-lowering action based on human and animal studies. So when you stack the two, the worry is that your sugar could drop a little too far, a condition we call hypoglycemia.

If that happens, you might feel shaky, sweaty, dizzy, irritable, or suddenly very hungry. This isn't a dangerous chemical clash, it's just two things pushing blood sugar in the same direction. If you'd like to try Giloy, please check with your pharmacist or doctor first. They may want you to monitor your readings a bit more closely at the start.

  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Nateglinide page

“People who take nateglinide (Starlix) with meals for type 2 diabetes are often drawn to supplements marketed for blood sugar, and that overlap is why these 290 interactions warrant real caution. Some 239 of the ingredients affect blood sugar on their own, most pushing it lower, so stacking them on nateglinide raises the odds of hypogly…”
