Guarumo and Dulaglutide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Dulaglutide

Dulaglutide falls under ANTIDIABETES DRUGS — the group Guarumo interacts with.

Some clinical evidence suggests that drinking tea prepared with guarumo leaf might lower blood glucose levels in people with type 2 diabetes. Theoretically, guarumo might have additive effects when used with antidiabetes drugs. Monitor blood glucose levels closely. Dose adjustments might be necessary. 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 B

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: guarumo tea may nudge your blood sugar down a bit on its own, and Trulicity (dulaglutide) is already doing that same job. Stack the two together and the effect can add up, so your sugar could drop lower than you expect. Watch for signs of low blood sugar like shakiness, sweating, dizziness, headache, or feeling suddenly tired or confused.

This isn't a dangerous chemical clash, and the evidence behind guarumo is still pretty thin and based on lower quality studies. The realistic concern is just extra sugar-lowering. If you want to try guarumo, check your glucose more often at first and loop in your pharmacist or doctor before changing anything, since your Trulicity dose might need a tweak.

From our pharmacist’s overview on the Dulaglutide page

“Because dulaglutide (Trulicity) already lowers blood sugar in people with type 2 diabetes, nearly every entry on this page deserves genuine respect, and one demands it outright. Almost all of these supplements pull glucose in one direction or the other, so the danger that matters most is hypoglycemia, blood sugar dropping too low.”

About Guarumo

What is Guarumo?

Guarumo
  • Type 2 diabetes / blood sugar support
  • High blood pressure
  • Cough, asthma, and bronchitis
  • Heart failure symptoms
  • Liver and rheumatic complaints

Guarumo (Cecropia obtusifolia) is a tropical tree used in Latin American traditional medicine, most often as a leaf tea for diabetes and high blood pressure. Some early laboratory and small human studies suggest it may modestly affect blood sugar, but the evidence is limited and not strong enough to recommend it as a treatment. Talk with your pharmacist or doctor before using it, especially if you have a chronic condition or take medication.
