Drug & supplement interaction

Tangerine + Dacomitinib

Dacomitinib brand name: Vizimpro.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Tangerine and Dacomitinib 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.

Tangerine and Dacomitinib

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 Dacomitinib and Tangerine 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 Dacomitinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dacomitinib is filed under 2 classifications — cytochrome p450 2d6 (cyp2d6) inhibitors, oral drugs. Tangerine has documented interactions with 2 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (minor) and midazolam (versed) (minor) — and none of Dacomitinib’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 Tangerine and Dacomitinib May Share a Side Effect

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.

Effects for Dacomitinib come from the ADVERSE REACTIONS section of its FDA label; effects for Tangerine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 746 voluntary FDA FAERS reports for Dacomitinib 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.

Overlapping uses

What Dacomitinib Is Prescribed For, and What Tangerine Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Dacomitinib is a prescription medicine with approved uses on its FDA label. Tangerine is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Dacomitinib is prescribed for: Vizimpro (dacomitinib) is used as a first-line treatment for adults with metastatic non-small cell lung cancer (NSCLC) — meaning lung cancer that has spread — when the tumor carries a specific genetic change in the EGFR gene (an exon 19 deletion or exon 21 L858R substitution mutation). Before starting, your tumor must be tested with an FDA-approved test to confirm one of these mutations is present.

  • Cancer studied, not established Tangerine has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Tangerine for cancer

    Observational research has found that daily intake of oranges and/or tangerines is associated with a reduced odds of developing nasopharyngeal carcinoma when compared with consuming oranges and/or tangerines less than once a week.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Dacomitinib on your own; if you are taking Tangerine for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Dacomitinib page

“Dacomitinib (Vizimpro) is a once-daily pill for EGFR-mutated lung cancer, and this list deserves real attention because the treatment only works if the full dose reaches your bloodstream. Seventeen of the 20 ingredients on file are fibers, gums, and binders that can blunt how much of an oral drug gets absorbed, and the single major-rat…”

About Tangerine

What is Tangerine?

  • Source of vitamin C
  • Digestive support
  • Aromatherapy and relaxation
  • Cough and phlegm (traditional)
  • Skin and flavoring uses

Tangerine is a sweet citrus fruit that is a good source of vitamin C and other nutrients, and is widely enjoyed as food. While the peel and essential oil are used in traditional medicine and aromatherapy, strong human evidence for specific health benefits beyond basic nutrition is limited. Enjoying tangerines as part of a balanced diet is generally safe for most people.

Citrus reticulata · Rutaceae · Fruit, peel, and essential oil · Fresh fruit, juice, dried peel, essential oil, capsules, extracts

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

Tangerine: dosing

There is no official or standardized medicinal dose for tangerine. As a food, you can simply enjoy it the way you would any fruit.For peel, extracts, essential oil, or capsule products, there is no established dose proven safe and effective for any condition. Essential oils are for external or aromatherapy use only unless a professional advises otherwise.

Taking Tangerine and Dacomitinib Together: Common Questions

Is it safe to take Tangerine with Dacomitinib?
We do not list a known interaction between Tangerine and Dacomitinib. 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 Tangerine and Dacomitinib have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Are Tangerine and Dacomitinib used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Tangerine in each. That is a conversation for your prescriber, especially if Dacomitinib is being adjusted to a target.
How was the Tangerine and Dacomitinib combination checked?
Interactions in our licensed database are recorded against drug classes. Dacomitinib is filed under 2 classifications, and Tangerine has documented interactions with 2 drug classes — none of Dacomitinib'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 Tangerine interact with any other medications?
Yes. Tangerine has 643 documented drug interactions in our database — Dacomitinib 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 Dacomitinib interact with any supplements?
Yes. Dacomitinib has documented interactions with 20 supplements in our database — Tangerine is not one of them. The Dacomitinib interaction page linked on this page lists every one, ranked by severity.
