Papaya and Glucose

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Glucose

Glucose falls under ANTIDIABETES DRUGS — the group Papaya interacts with.

Concomitant use of antidiabetic drugs with fermented papaya can produce additive effects. It is unclear if other forms of papaya have the same effect.
A small low-quality clinical study in patients with type 2 diabetes who are taking glibenclamide shows that taking a fermented papaya preparation 3 grams daily for 2 months decreases fasting and postprandial blood glucose levels when compared to baseline. Additionally, of the 25 patients in the study, 9 required a reduction in glibenclamide dose.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: papaya, especially a fermented papaya preparation, may gently lower blood sugar on its own. In one small, lower-quality study of people with type 2 diabetes, taking fermented papaya for two months brought down fasting and after-meal glucose, and some folks even needed less of their diabetes pill.

So if you're using glucose to raise a low blood sugar (like IV glucose or glucose tablets for hypoglycemia), papaya's sugar-lowering nudge could work against you a bit, making it slightly harder to bounce back. The evidence is weak and mostly tied to the fermented form, so plain papaya fruit as food is unlikely to matter much. Still, if you treat low blood sugars often, mention any papaya supplements to your pharmacist or doctor.

This page covers Papaya only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Glucose page lists 256 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 215 moderate · 39 minor.

From our pharmacist’s overview on the Glucose page

“Glucose given by IV raises a dangerously low blood sugar, and this list warrants real caution because most of its 256 ingredients pull the other way. Nearly all of them lower blood sugar on their own, working against the treatment and setting up another crash.”

About Papaya

What is Papaya?

Papaya
  • Digestive upset and indigestion
  • Constipation
  • Wound and skin care (topical)
  • Intestinal parasites (traditional)
  • Supporting platelet counts in dengue (investigational)

Papaya is a tropical fruit that is nutritious and generally safe to eat as food, and it contains an enzyme called papain used as a digestive aid and meat tenderizer. Papaya leaf extract is being studied for raising platelet counts in dengue fever, but most other supplement uses have limited human evidence. Talk to your pharmacist or doctor before using concentrated papaya supplements, and avoid unripe (green) papaya and papaya seed products in pregnancy.
