German Chamomile and Pazopanib

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Pazopanib

Pazopanib falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group German Chamomile interacts with.

Theoretically, German chamomile might inhibit CYP3A4 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP3A4. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP3A4 in patients taking German chamomile.
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: your body clears pazopanib using a liver enzyme called CYP3A4. German chamomile, in lab (test tube) studies, appears to slow that enzyme down a bit. If that same effect happened in people, your pazopanib could clear more slowly and build up higher than expected. Pazopanib is active as-is, not a prodrug, so more of it means a stronger effect and a higher chance of side effects like high blood pressure, diarrhea, nausea, fatigue, liver enzyme changes, or rarely heart-rhythm problems.

I want to be honest, though: this is only theoretical so far and has not been seen in real patients, and an occasional cup of chamomile tea is unlikely to matter much. Still, since pazopanib is a serious cancer medicine, please run any chamomile supplements or regular tea use past your oncologist or pharmacist first.

From our pharmacist’s overview on the Pazopanib page

“Take a careful look before mixing supplements with pazopanib (Votrient), an oral pill for advanced kidney cancer and certain sarcomas. Fourteen of the 349 ingredients on file are rated major, grapefruit among them, since it can raise pazopanib levels enough to intensify side effects.”

About German Chamomile

What is German Chamomile?

German Chamomile
  • Anxiety and stress
  • Sleep and relaxation
  • Digestive upset
  • Skin irritation and inflammation
  • Mouth sores and gum irritation

German chamomile is a widely used herbal remedy taken mainly as a tea for calming, sleep, and digestive complaints. Early research suggests possible benefits for mild anxiety and some skin or digestive issues, but the evidence is limited and most uses are based on tradition rather than strong proof. It is generally well tolerated, but people allergic to ragweed or related plants and those who are pregnant should be cautious.

About Pazopanib

What Is Pazopanib Used For?

Brand name: Votrient

Pazopanib tablets — sold as the brand Votrient and as generic pazopanib — are used to treat two types of advanced cancer in adults: advanced renal cell carcinoma (RCC), the most common form of kidney cancer, and advanced soft tissue sarcoma (STS) in patients who have already received prior chemotherapy.

Important limitation: Pazopanib has not been shown to work in adipocytic soft tissue sarcoma (a subtype involving fat cells) or in gastrointestinal stromal tumors (GISTs), so it is not used for those cancers.
