Kousso and Ertugliflozin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Ertugliflozin

Ertugliflozin falls under ANTIDIABETES DRUGS — the group Kousso interacts with.

Theoretically, kousso might have an additive effect with antidiabetes drugs and cause hypoglycemia. Animal research shows that kousso flower extract modestly decreases blood glucose levels in diabetic mice.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: Kousso is an old-fashioned tapeworm remedy, and in some animal studies its flower extract nudged blood sugar down a little. Ertugliflozin (Steglatro) already lowers blood sugar by flushing extra glucose out through your urine. So the worry is simply additive: two things pushing blood sugar in the same direction could push it too low.

I want to be honest about how thin the evidence is. This is theoretical, based only on lab and mouse research, so I wouldn't lose sleep over it. Still, if your sugar dipped, you might feel shaky, sweaty, dizzy, or foggy. Kousso also has its own harsh side effects and isn't really recommended anymore. Please check with your pharmacist or doctor before pairing them.

From our pharmacist’s overview on the Ertugliflozin page

“Ertugliflozin (Steglatro) works by making your kidneys flush out extra sugar, and nearly all 256 supplements on this page pull on that same lever, so this is a list to approach carefully rather than casually. Most entries either add to the glucose-lowering effect and raise the risk of a low, or, like niacin, push blood sugar the other…”

About Kousso

What is Kousso?

  • Tapeworm infection (traditional anthelmintic)
  • Other intestinal worms
  • Traditional digestive remedies

Kousso is the dried flower of the African tree Hagenia abyssinica, used traditionally—especially in Ethiopia—to expel tapeworms. It was once listed in older pharmacopeias as a worm treatment, but it has largely been replaced by safer, more reliable modern medicines and can cause significant side effects. There is no good modern evidence supporting its use, so talk to a pharmacist or doctor before considering it.
