Tiratricol and Acetohexamide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Acetohexamide

Acetohexamide falls under ANTIDIABETES DRUGS — the group Tiratricol interacts with.

Theoretically, tiratricol might interfere with blood glucose control.
Tiratricol is related to thyroid hormones, such as levothyroxine, which can interfere with blood glucose control and necessitate adjustment of diabetes drug therapy. It is not known if tiratricol has these effects.
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

Acetohexamide is an older sulfonylurea that helps lower your blood sugar by nudging your pancreas to release more insulin. Tiratricol acts a lot like the thyroid hormone T3, and thyroid hormones tend to raise blood sugar. So in theory, adding tiratricol could push your sugar up and work against what acetohexamide is doing, possibly leaving your readings higher than usual.

I want to be honest with you here: this is only a theoretical concern based on how these substances behave, not something proven in studies. Just as important, tiratricol itself is not a safe or approved supplement and the FDA has warned against it, so my real advice is to steer clear of it entirely and check with your pharmacist or doctor before changing anything.

About Tiratricol

What is Tiratricol?

  • Weight loss
  • Fat burning
  • Boosting metabolism
  • Bodybuilding and cutting
  • Thyroid-related supplementation

Tiratricol (also called TRIAC) is a powerful synthetic thyroid hormone metabolite, not a natural herb, and it has been illegally added to some weight-loss and bodybuilding supplements. It can cause serious heart and thyroid problems, and the U.S. FDA has warned consumers not to use products containing it. It is not a safe or approved dietary supplement, and you should avoid it.
