Goji and Zanubrutinib

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Zanubrutinib

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

Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.
In vitro research shows that goji berry juice inhibits CYP3A4 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this 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 simple version. Your body clears zanubrutinib (Brukinsa) mainly through a liver enzyme called CYP3A4. Lab studies suggest goji berry juice may slow that same enzyme down. If it does, your body could clear zanubrutinib a little more slowly, letting levels creep up. That could mean more of the usual side effects, like bruising or bleeding, low blood counts, infections, or feeling extra tired.

The honest part: this is only seen in test-tube research so far, never confirmed in real people, so I don't want to alarm you. A few goji berries in food are unlikely to be a problem. Concentrated goji supplements or daily goji juice are a different story. Since zanubrutinib is a serious cancer medicine, please run it past your oncologist or pharmacist before adding goji.

From our pharmacist’s overview on the Zanubrutinib page

“Grapefruit is the biggest supplement risk with zanubrutinib (Brukinsa), a targeted therapy for certain blood cancers, and this list deserves genuine care. Grapefruit blocks the enzyme (CYP3A4) that clears the drug, so levels can climb and side effects with them.”

About Goji

What is Goji?

Goji
  • General antioxidant support
  • Eye health
  • Immune support
  • Anti-aging and well-being
  • Blood sugar support

Goji berries are a nutritious fruit rich in antioxidants, vitamins, and plant polysaccharides, and they are safe for most people as a food. While they are popular for eye health, immune support, and general wellness, strong human evidence for most health claims is limited. Talk with your pharmacist or doctor before using concentrated goji supplements, especially if you take medications or are pregnant.

About Zanubrutinib

What Is Zanubrutinib Used For?

Brand name: Brukinsa

Brukinsa (zanubrutinib) is used to treat adult patients with several blood cancers. These include chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Waldenström's macroglobulinemia (WM), mantle cell lymphoma (MCL) after at least one prior treatment, relapsed or refractory marginal zone lymphoma (MZL) after at least one prior anti-CD20 regimen, and relapsed or refractory follicular lymphoma (FL) in combination with obinutuzumab after two or more prior lines of treatment.

Some of these uses — MCL, MZL, and FL — are approved under accelerated approval, meaning they are based on tumor response rates rather than confirmed long-term survival benefit. Continued approval for those uses may depend on results from confirmatory trials.
