Cassia Auriculata and Troglitazone

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Troglitazone

Troglitazone falls under ANTIDIABETES DRUGS — the group Cassia Auriculata interacts with.

Theoretically, Cassia auriculata may reduce blood glucose levels and might have additive effects on glucose levels when used with antidiabetes drugs. Monitor blood glucose levels closely. Medication dose adjustments may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
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 gist: Troglitazone (Rezulin) is a diabetes medicine that helps lower your blood sugar. Cassia auriculata has been studied, mostly in lab and animal research, for its own blood-sugar-lowering effects. So if you took both together, the worry is that they could stack up and push your glucose down further than expected. That can lead to low blood sugar (hypoglycemia), with signs like shakiness, sweating, dizziness, confusion, or feeling unusually tired.

I'll be honest with you, this is a theoretical concern based on weak evidence, not strong human studies, so it's not a reason to panic. Troglitazone itself isn't a prodrug, so the issue here is simply additive effect. Don't change anything on your own. Check in with your pharmacist or doctor first, and watch your blood sugar readings closely if you do use both.

From our pharmacist’s overview on the Troglitazone page

“Most people taking troglitazone (Rezulin) are managing type 2 diabetes, and this list reflects that. The great majority of the 280 flagged ingredients act on blood sugar, most lowering it and a few raising it, so pairing them with a diabetes medication makes glucose control less predictable and can tip it too low.”

About Cassia Auriculata

What is Cassia Auriculata?

  • Digestive upset
  • General tonic and antioxidant

Cassia auriculata (often called Tanner's cassia or Avaram) is a flowering shrub used in traditional Indian medicine, especially for blood sugar and skin concerns. Most evidence comes from laboratory and animal studies, so its benefits in people are not well proven. Talk to your pharmacist or doctor before using it, particularly if you take diabetes medicine or are pregnant.
