Ginger and Pomalidomide

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Ginger interacts with whole categories of medication. Pomalidomide falls into 3 of those categories, so it can interact with Ginger in 3 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 3

Why this applies to Pomalidomide

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

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, 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.

Here's the situation with ginger and Pomalyst (pomalidomide). Your body partly clears pomalidomide using a liver enzyme called CYP3A4, and ginger may nudge that enzyme in either direction. If ginger slows the enzyme down, pomalidomide could build up a bit, which might mean more of its known side effects like low blood counts, fatigue, or a higher infection risk. If ginger speeds the enzyme up instead, the drug could clear faster and work less well.

I want to be honest about the evidence here: this is mostly lab and animal data, with only a few unclear case reports involving other cancer drugs. Normal cooking amounts of ginger are very unlikely to matter. Before starting a concentrated ginger supplement, please check with your oncology pharmacist or doctor so they can weigh in.

P-GLYCOPROTEIN SUBSTRATES

2 of 3

Pomalidomide also falls under P-GLYCOPROTEIN SUBSTRATES.

Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
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 idea with ginger and Pomalyst (pomalidomide). Ginger may block a pump in your gut called P-glycoprotein, which normally helps move some drugs back out of your body. Since pomalidomide is partly handled by that pump, blocking it could let a bit more of the drug get absorbed, nudging your blood levels up. With a strong cancer medicine like this, even small bumps could mean more side effects, think low blood counts, fatigue, infections, or a higher risk of blood clots.

I want to be honest about the evidence, though: this is based mostly on lab studies and a couple of fuzzy case reports with other cancer drugs, so it's far from proven. Food amounts of ginger are unlikely to be a problem. Before using ginger supplements, just check with your oncologist or pharmacist.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

3 of 3

Pomalidomide also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.

Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.
Severity Minor 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 Pomalyst (pomalidomide) and ginger. Pomalidomide is partly cleared by a liver enzyme called CYP1A2. In a test-tube setting, ginger appears to slow that enzyme down a bit. If that happened in your body, pomalidomide could clear a little slower and build up slightly, which in theory might nudge its side effects, things like low blood counts, fatigue, and a higher infection or clot risk.

The important part: this is only lab-dish data and has never actually been seen in people, so the real-world risk looks low. Pomalidomide is a serious cancer drug, though, so don't add a ginger supplement on your own. A little ginger in food is unlikely to matter, but please run any supplement past your oncology team or pharmacist first.

  • Menstrual cramps
  • Joint pain and inflammation

Ginger is a widely used culinary spice with a long history in traditional medicine, and it has the strongest evidence for helping with nausea and vomiting, including from motion sickness, pregnancy, and chemotherapy. It is generally safe in food and supplement amounts for most people, though it may cause mild stomach upset. Talk with your pharmacist or doctor before using ginger supplements, especially if you are pregnant, have a bleeding disorder, or take other medicines.

About Pomalidomide

What Is Pomalidomide Used For?

Brand name: Pomalyst

Pomalidomide capsules are used in adults with multiple myeloma (a blood cancer affecting plasma cells) who have already tried at least two prior treatments — including lenalidomide and a proteasome inhibitor — and whose disease has continued to progress. It is given in combination with dexamethasone for this use.

Pomalidomide capsules are also used to treat Kaposi sarcoma (KS) — a cancer that can cause lesions on the skin and in internal organs — both in adults with AIDS-related KS after antiretroviral therapy has stopped working, and in adults with KS who are HIV-negative. The KS indication was approved based on response rate; ongoing studies are confirming long-term benefit.
