Moringa and Crizotinib

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

Why Are There 2 Interactions?

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Crizotinib

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

Theoretically, moringa might increase or decrease levels of CYP3A4 substrates.
Some in vitro research suggests that moringa inhibits cytochrome P450 3A4 (CYP3A4). However, other in vitro research suggests that moringa extract induces CYP3A4 enzymes. A pharmacokinetic study in patients with HIV shows no change in the pharmacokinetics of nevirapine, which is partially metabolized by CYP3A4, when administered concomitantly with moringa leaf powder 1.85 grams daily for 14 days.
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 explains PharmD, Clinical Pharmacist

Here's the situation with moringa and crizotinib (Xalkori). Your body relies on a liver enzyme called CYP3A4 to break this cancer drug down, and lab studies suggest moringa could nudge that enzyme in either direction. If moringa slows the enzyme, crizotinib may build up, which could mean more nausea, vomiting, diarrhea, swelling, vision changes, or strain on your heart rhythm and liver. If moringa instead speeds the enzyme up, your crizotinib levels could drop and the drug might not work as well against your cancer.

Honestly, this is mostly theory from test-tube research, and one human study found no real change with a different drug. Still, crizotinib is too important to gamble with, so please run any moringa supplement past your oncologist or pharmacist first. Small amounts in food are far less likely to matter than concentrated capsules.

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Crizotinib also falls under P-GLYCOPROTEIN SUBSTRATES.

Theoretically, moringa leaf extract might increase the levels and clinical effects of P-glycoprotein substrates.
In vitro research shows that moringa leaf extract inhibits renal P-glycoprotein transport activity. So far, this reaction 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 is the gist for Xalkori (crizotinib). Your body uses a kind of cellular pump called P-glycoprotein to move certain drugs around and help clear them. Lab studies suggest moringa leaf extract may slow that pump down. If that happened in people, more crizotinib could stay in your system, which in theory could mean stronger effects and more side effects like nausea, vision changes, swelling, fatigue, or liver and heart rhythm concerns.

I want to be honest with you though: this is based only on test-tube research, and it has not actually been seen in humans. Eating moringa as food is unlikely to be a problem, but concentrated supplements are a different story. Since crizotinib is a serious cancer medicine, please run any moringa supplement past your oncologist or pharmacist first.

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.
  • DAnecdotal evidence.

From our pharmacist’s overview on the Crizotinib page

“Grapefruit tops my worry list for crizotinib (Xalkori), a targeted pill for ALK-positive lung cancer. It blocks the enzyme (CYP3A4) that clears crizotinib, letting levels climb and side effects with them, and it is one of eight major-rated entries among the 157 supplements and herbs on file for this drug.”

About Moringa

What is Moringa?

  • Nutritional supplement
  • Blood sugar support
  • Cholesterol support
  • Inflammation
  • Skin conditions

Moringa is a nutrient-rich plant whose leaves are widely used as a food and supplement, especially in parts of the world where malnutrition is common. Early research hints at possible benefits for blood sugar, cholesterol, and inflammation, but the human evidence is limited and not strong enough to recommend it as a treatment. Talk with your pharmacist or doctor before using moringa, especially if you are pregnant, breastfeeding, or taking medications.
