Strawberry and Pazopanib

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Strawberry interacts with whole categories of medication. Pazopanib falls into 2 of those categories, so it can interact with Strawberry in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

P-GLYCOPROTEIN SUBSTRATES

1 of 2

Why this applies to Pazopanib

Pazopanib falls under P-GLYCOPROTEIN SUBSTRATES — the group Strawberry interacts with.

In vitro research suggests that strawberry extract can inhibit p-glycoprotein efflux. Theoretically, strawberry might inhibit p-glycoprotein mediated drug efflux and potentially increase levels of drugs that are substrates of p-glycoprotein. Until more is known, strawberry should be used cautiously in people taking p-glycoprotein substrates.
Drugs that might be affected include some chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), protease inhibitors (amprenavir, indinavir, nelfinavir, saquinavir), H2 antagonists (cimetidine, ranitidine), some calcium channel blockers (diltiazem, verapamil), corticosteroids, erythromycin, cisapride (Propulsid), fexofenadine (Allegra), cyclosporine, loperamide (Imodium), quinidine, and others.
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.

Here's the gist for pazopanib (Votrient): it's carried around by a transporter called P-glycoprotein, which acts like a little pump moving the drug out of your cells. Lab studies (test-tube only) hint that strawberry extract may slow that pump down. If that happened in the body, more pazopanib could stay in your system, which in theory could mean stronger side effects like high blood pressure, diarrhea, fatigue, nausea, or changes in liver tests.

I want to be honest about the evidence, though. This is based on in vitro data, not real patients, and eating strawberries as a normal food is very different from a concentrated extract. Enjoying a handful of berries is unlikely to be a problem, but before using strawberry supplements, please run it by your oncologist or pharmacist.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Pazopanib also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

In vitro and animal research suggests that strawberry extract can inhibit platelet aggregation due to its phenolic content. Theoretically, strawberry might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
Severity Moderate Likelihood Possible Evidence D

Here's the connection worth knowing. Pazopanib (Votrient) isn't a blood thinner itself, but it can raise your bleeding risk on its own, since it slows the growth of blood vessels that tumors rely on. Strawberry got placed on this list because lab and animal studies hint that its plant compounds (polyphenols) might make platelets a little less sticky, which could theoretically add to that bleeding tendency.

I want to keep this in perspective. This warning rests on test-tube and animal data only, not human studies, so it's largely theoretical. Enjoying strawberries as a normal food is very unlikely to cause trouble. Concentrated strawberry extract supplements are a bigger unknown. If you bruise easily, notice nosebleeds, or see blood, call your oncology team, and check with them before starting any strawberry supplement.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

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.”

Strawberry is a popular, nutrient-rich fruit that supplies vitamin C, fiber, and antioxidant plant compounds.

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.
