Drug & supplement interaction

Nickel + Crizotinib

Crizotinib brand name: Xalkori.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Nickel and Crizotinib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Nickel and Crizotinib

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Crizotinib and Nickel in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Crizotinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Crizotinib is filed under 5 classifications — including qt interval-prolonging drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, p-glycoprotein substrates. Nickel has documented interactions with 1 drug class — the most serious being disulfiram (antabuse) (moderate) — and none of Crizotinib’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Nickel and Crizotinib May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

    “Orally and topically, nickel can cause hypersensitivity reactions in sensitized individuals. Nickel sensitivity, which can cause dermatologic and gastrointestinal symptoms, has an estimated prevalence of 11% in the general population, with a higher overall incidence in females than in males. About 10% of nickel-sensitive people react to ingestion of 550-1300 mcg.”

Reported for Nickel but not commonly for Crizotinib: a severe allergic reaction, an allergic reaction, kidney problems and hives.

Effects for Crizotinib come from the ADVERSE REACTIONS section of its FDA label; effects for Nickel come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 12,638 voluntary FDA FAERS reports for Crizotinib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Nickel in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally and appropriately. Nickel is safe to use during pregnancy and lactation in doses below the tolerable upper intake level (UL) of 1 mg daily. There is insufficient reliable information available about the safety of nickel when taken in doses above the UL during pregnancy and lactation.

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 Nickel

What is Nickel?

  • General trace-mineral supplementation
  • Supporting iron and other nutrient metabolism (theoretical)
  • Marketed for bone or hormone support

Nickel is a trace element found in tiny amounts in many foods, and most people get plenty through diet. There is no proven need for nickel supplements, and because nickel is a common cause of allergic reactions and can be toxic in higher amounts, most people should not take it. Talk with your pharmacist or doctor before using any nickel-containing supplement.

Trace mineral (metallic element) · Tablets, capsules, and as part of some multivitamin or trace-mineral supplements (often as nickel sulfate or nickel chloride)

An interaction check asks whether these two react with each other — it does not ask whether Nickel is a good idea for someone in your situation. Here is what our Nickel record says about it on its own.

Nickel: dosing

There is no established recommended supplement dose of nickel, because a clear human requirement has not been proven and most people get enough from food. Health authorities have set upper limits to help avoid harmful exposure, but this does not mean people need to take supplements to reach any amount.If a product contains nickel, follow the label and do not take more than directed.

About Crizotinib

What Is Crizotinib Used For?

Brand name: Xalkori

Xalkori (crizotinib) is used to treat adult patients with metastatic non-small cell lung cancer (NSCLC) whose tumors test positive for the ALK or ROS1 gene abnormality, as confirmed by an FDA-approved test.

Xalkori is also used to treat pediatric patients aged 1 year and older and young adults with relapsed or refractory systemic ALK-positive anaplastic large cell lymphoma (ALCL). Additionally, it treats adult and pediatric patients aged 1 year and older with unresectable, recurrent, or refractory ALK-positive inflammatory myofibroblastic tumor (IMT). Note: Xalkori's safety and effectiveness in older adults with relapsed or refractory ALK-positive ALCL have not been established.

Most-Reported Side Effects for Crizotinib

From FAERS, the FDA’s public side-effect reporting system (12,638 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Nickel and Crizotinib Together: Common Questions

Is it safe to take Nickel with Crizotinib?
We do not list a known interaction between Nickel and Crizotinib. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Nickel and Crizotinib have any of the same side effects?
Yes — our sources link each of them separately to 9 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Nickel and Crizotinib combination checked?
Interactions in our licensed database are recorded against drug classes. Crizotinib is filed under 5 classifications, and Nickel has documented interactions with 1 drug class — none of Crizotinib's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Nickel interact with any other medications?
Yes. Nickel has 1 documented drug interaction in our database — Crizotinib is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Crizotinib interact with any supplements?
Yes. Crizotinib has documented interactions with 157 supplements in our database — Nickel is not one of them. The Crizotinib interaction page linked on this page lists every one, ranked by severity.
