Honey and Dolasetron

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Dolasetron

Dolasetron 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 gist for dolasetron (Anzemet), which your care team uses to stop nausea and vomiting during chemo. Some studies suggest honey might speed up a liver enzyme called CYP3A4, and dolasetron is partly handled by that pathway. In theory, that could clear the drug a little faster and make it work a bit less well, meaning nausea control might not be quite as strong.

I want to be honest, though: this is a very weak, theoretical concern. The research actually conflicts, with some studies showing no effect at all, and any impact from normal food amounts of honey is likely tiny. Still, if you're on chemo, it's worth a quick mention to your oncology pharmacist so nothing slips through.

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.
