Sweet Annie and Acarbose

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Acarbose

Acarbose falls under HEPATOTOXIC DRUGS — the group Sweet Annie interacts with.

Theoretically, concomitant use might have additive adverse hepatotoxic effects.
There is some concern that Sweet Annie can adversely affect the liver.
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: this isn't about Sweet Annie changing how acarbose works or how your blood sugar responds. Acarbose acts right in your gut to slow sugar absorption, so the two don't really clash on that level. The concern is the liver. Acarbose can, in rare cases, bump up liver enzymes, and there's some worry that Sweet Annie may stress the liver too. Put together, the thinking is they could add up and be a little harder on your liver.

I'll be honest, this is theoretical and based on weak, anecdotal reports, so don't panic. Still, watch for things like yellowing skin or eyes, dark urine, belly pain, or unusual tiredness, and check with your pharmacist or doctor before combining them.

About Sweet Annie

What is Sweet Annie?

Sweet Annie
  • Malaria (traditional)
  • Fever
  • Inflammation
  • Digestive complaints
  • Antimicrobial support
  • Insect repellent

Sweet Annie (Artemisia annua) is the source of artemisinin, a compound used in prescription antimalarial drugs. While the purified drug is well studied for malaria, the herb itself as a supplement is not proven for the wide range of conditions people use it for, and self-treating malaria with the raw herb is dangerous. Talk to a pharmacist or doctor before using it.

About Acarbose

What Is Acarbose Used For?

Brand names: Precose, Prandase, Glucobay

Acarbose tablets are used to help control blood sugar in adults with type 2 diabetes. They are always used together with a proper diet and regular exercise — not as a replacement for them.

Acarbose can be used on its own or combined with other diabetes medicines such as sulfonylureas, insulin, or metformin to get better blood sugar control.
