Interaction report

Fig and Insulin (rDNA)

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Fig interacts with whole categories of medication. Insulin (rDNA) falls into 2 of those categories, so it can interact with Fig in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTIDIABETES DRUGS

1 of 2

Why this applies to Insulin (rDNA)

Insulin (rDNA) falls under ANTIDIABETES DRUGS — the group Fig interacts with.

Theoretically, fig leaf might enhance the blood glucose lowering effects of hypoglycemic drugs.
A small clinical study in patients with type 1 diabetes shows that consuming a tea made from fig leaves modestly reduces postprandial glucose levels and insulin requirements.
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 explains PharmD, Clinical Pharmacist

Here's the thing to keep an eye on: fig leaf may have a mild blood sugar lowering effect of its own. When you stack that on top of your insulin (Humalog, Humulin, and similar), the two can add together and push your glucose down more than you'd expect. In one small study in people with type 1 diabetes, drinking fig leaf tea actually lowered their insulin needs a bit.

So the practical worry is low blood sugar (hypoglycemia), which can show up as shakiness, sweating, dizziness, a fast heartbeat, or confusion. This is mainly about concentrated fig leaf products or fig leaf tea, not eating a few figs as food. Please don't change your insulin dose on your own. If you want to try fig leaf, check with your pharmacist or doctor first so they can help you watch your numbers.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for your insulin (like Humalog or Humulin): fig leaf, often taken as a tea, appears to lower blood sugar on its own. When you stack that on top of your insulin, the two can add up and push your sugar down further than expected. A small study in people with type 1 diabetes actually saw lower after-meal sugars and a slightly reduced insulin need.

The thing to watch for is low blood sugar (shakiness, sweating, confusion, a racing heart, feeling faint). This is about concentrated fig leaf products, not eating a few figs, which mostly just add fiber. Don't change your insulin dose on your own. If you want to try fig leaf, check in with your doctor or pharmacist first so they can watch your numbers.

This page covers Fig only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Insulin (rDNA) page lists 242 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 2 major · 211 moderate · 29 minor.

From our pharmacist’s overview on the Insulin (rDNA) page

“A weed called Siberian cocklebur has caused severe low blood sugar in humans and is the one ingredient to avoid outright while using insulin (rDNA) products like Humalog or Humulin. This list deserves real respect.”

About Fig

What is Fig?

  • Constipation and digestive health
  • Blood sugar support
  • Cough and sore throat
  • Skin conditions (topical sap)
  • Source of fiber and minerals

Fig (Ficus carica) is a common fruit that has long been used as a gentle food remedy for constipation, and its leaves are used traditionally for blood sugar and coughs. The fruit is a safe and nutritious food, but evidence for fig leaf supplements treating specific health conditions is limited. Talk to your pharmacist or doctor before using concentrated fig leaf products, especially if you have diabetes.
