Honey and Fruquintinib

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Fruquintinib

Fruquintinib falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Honey interacts with.

Theoretically, honey might decrease levels of drugs metabolized by CYP3A4, but research is conflicting.
Some clinical research shows that honey induces CYP3A4. However, other clinical studies found no effect on CYP3A4 activity. Different honey preparations may have different effects on CYP3A4.
Severity Minor 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 situation with honey and Fruquintinib (Fruzaqla), your oral cancer medicine used for certain colorectal cancers. Fruquintinib is broken down in part by a liver enzyme called CYP3A4. Some studies hint that honey may slightly speed up (induce) this enzyme, which in theory could clear the drug a bit faster and make it less effective. But honestly, the evidence is weak and conflicting, and different honeys behave differently.

The good news: normal food amounts of honey, like a spoonful in tea, are very unlikely to matter here. Because fruquintinib is such an important, tightly dosed cancer therapy, I'd still mention any regular or concentrated honey use to your oncology team so they can keep an eye on things. Don't change anything on your own.

About Honey

What is Honey?

Honey
  • Cough and sore throat
  • Wound and burn care
  • Soothing minor skin irritation
  • Sweetener and home remedy
  • Digestive upset

Honey is a natural food with some real, modest evidence for easing coughs and helping certain wounds, especially when special medical-grade or Manuka honey is used. It is generally safe for most adults and children over 1 year, but should never be given to infants under 12 months because of the risk of botulism.

About Fruquintinib

What Is Fruquintinib Used For?

Brand name: Fruzaqla

Fruzaqla (fruquintinib) is used to treat adults with metastatic colorectal cancer (mCRC) — colorectal cancer that has spread to other parts of the body. It is specifically for patients who have already been treated with several standard chemotherapy regimens and other targeted therapies.

Fruzaqla is intended for patients who have previously received fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, an anti-VEGF therapy, and — if their tumor is RAS wild-type and it is medically appropriate — an anti-EGFR therapy.
