English Ivy and Paclitaxel

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

Moderate

CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES

Why this applies to Paclitaxel

Paclitaxel falls under CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES — the group English Ivy interacts with.

Theoretically, English ivy might increase the levels of drugs metabolized by CYP2C8.
In vitro research shows that English ivy inhibits CYP2C8 enzymes. So far, this interaction has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

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 anyone getting paclitaxel (Taxol or Abraxane): your liver clears this chemo drug largely through an enzyme called CYP2C8. In lab dish studies, English ivy appears to slow that same enzyme down. If that played out in the body, paclitaxel could clear a bit slower and build up, which in theory might mean stronger side effects like low blood counts, nerve tingling or numbness in the hands and feet, fatigue, or mouth sores.

I want to be straight with you, though: this is only seen in test-tube research and has never actually been reported in people, so it's more of a caution than a proven problem. Since paclitaxel is serious chemo, please don't add any ivy cough product without first clearing it with your oncology team or pharmacist.

About English Ivy

What is English Ivy?

English Ivy
  • Cough and chest congestion
  • Bronchitis
  • Asthma symptoms
  • Sore throat
  • Skin irritation

English ivy leaf extract is most commonly used in cough and cold syrups to help loosen mucus and ease coughing, and it is a popular ingredient in many European herbal products. Some research suggests it may help with certain coughs, but the evidence is still limited and mixed. The raw plant is poisonous if eaten and can irritate skin, so only use properly prepared commercial products and check with your pharmacist first.
