Hoodia and Linagliptin, Metformin Hydrochloride

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Linagliptin, Metformin Hydrochloride

Linagliptin, Metformin Hydrochloride falls under ANTIDIABETES DRUGS — the group Hoodia interacts with.

Animal research shows that a steroid glycoside of hoodia, gordonoside F, increases glucose-stimulated insulin secretion by activating GPR119. This effect enhances glucose disposal. Theoretically, concomitant use of hoodia with antidiabetes medications may enhance blood glucose-lowering effects and increase the risk of hypoglycemia. Some antidiabetes medications include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), 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

Jentadueto XR pairs two diabetes medicines (linagliptin and metformin) that already work to lower your blood sugar. The concern here is simple: hoodia might nudge your blood sugar down a little more on its own. In animal studies, one hoodia compound (gordonoside F) seemed to boost insulin release. So stacking it on top of your medication could add up to lower blood sugar than you want, meaning more chances of feeling shaky, sweaty, dizzy, or unusually hungry or tired.

Keep in mind this is theoretical, based only on lab and animal work, not real human cases, so I wouldn't lose sleep over it. Still, before adding hoodia, check with your pharmacist or doctor, and keep an eye on your sugar readings.

From our pharmacist’s overview on the Linagliptin, Metformin Hydrochloride page

“Someone taking Jentadueto XR (linagliptin and metformin) for type 2 diabetes is often the same person eyeing fenugreek, bitter melon, or gymnema, and that overlap is why this page deserves real caution. Of its 285 ingredients, 239 can lower blood sugar on their own, so stacking them on a drug already doing that job risks pushing glucos…”

About Hoodia

What is Hoodia?

Hoodia
  • Appetite suppression
  • Weight loss
  • Reducing food cravings
  • Traditional use for hunger and thirst on long journeys

Hoodia is a succulent plant from southern Africa that is marketed as an appetite suppressant for weight loss, but solid human evidence that it actually works is lacking. The few quality studies done have not shown meaningful weight loss, and some products on the market may not even contain real hoodia. Talk with your pharmacist or doctor before trying it, and avoid it if you are pregnant or breastfeeding.
