Drug & supplement interaction

Lutein + Gemcitabine

Gemcitabine brand name: Gemzar.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Lutein and Gemcitabine 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.

Lutein and Gemcitabine

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 Gemcitabine and Lutein 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Lutein at all — not against Gemcitabine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What Gemcitabine’s Own FDA Label Lists

This is not an interaction — none of it involves Lutein. These are the most notable effects listed in the ADVERSE REACTIONS section of Gemcitabine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • A stroke or mini-stroke Worth acting on
  • A heart attack Worth acting on
  • A low platelet count Worth acting on mentioned in 7.0% of FDA reports for Gemcitabine
  • An irregular heartbeat Worth acting on
  • Anemia Worth acting on mentioned in 5.8% of FDA reports for Gemcitabine
  • A low white blood cell count Worth acting on mentioned in 6.2% of FDA reports for Gemcitabine
  • Kidney problems Worth acting on
  • Raised blood pressure Worth acting on
  • Shortness of breath Worth acting on
  • Liver problems Worth acting on

Showing the 10 most notable of 16 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Gemcitabine. Read the label on DailyMed › Where a percentage is shown, it is the share of 53,020 voluntary FDA FAERS reports for Gemcitabine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Lutein’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Lutein side to compare — that is a limit of the record, not a statement that Lutein has no side effects.

Overlapping uses

What Gemcitabine Is Prescribed For, and What Lutein Has Been Studied For

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

Gemcitabine is prescribed for: Gemcitabine Injection (available as Avgemsi, Gemcitabine, and Infugem) is used to treat several types of cancer. It is given in combination with carboplatin for advanced ovarian cancer that has returned at least 6 months after platinum-based treatment, and in combination with paclitaxel as a first-line treatment for metastatic breast cancer after prior chemotherapy with an anthracycline (a specific class of chemo drug). It is also given in combination with cisplatin for non-small cell lung cancer (NSCLC) that cannot be removed surgically or has spread. For pancreatic cancer that is locally advanced or has spread, it is used as a single agent — including in patients who have already been treated with fluorouracil.

Lutein has been studied for:

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

    Lutein for breast cancer

    It is unclear if oral lutein is beneficial for breast cancer prevention.

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 Gemcitabine on your own; if you are taking Lutein for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Lutein

What is Lutein?

  • Eye health
  • Age-related macular degeneration
  • Cataract prevention
  • Reducing eye strain from screens
  • General antioxidant support

Lutein is a plant-based antioxidant pigment that concentrates in the eye, and the best evidence suggests it (often combined with zeaxanthin) may help slow progression of age-related macular degeneration in certain people. For most other eye and health claims, the evidence is limited or mixed. It is generally well tolerated, but talk to your pharmacist or doctor before starting it, especially during pregnancy or breastfeeding.

Pigment extracted from plants such as marigold flowers (Tagetes erecta) and found in leafy greens · Capsules, softgels, tablets, combination eye-health supplements, gummies

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

Lutein: dosing

There is no single official dose of lutein for supplements. Amounts used in eye-health research have varied, and lutein is often combined with zeaxanthin in eye formulas.The best approach is to follow the directions on the product label and not take more than recommended.

Taking Lutein and Gemcitabine Together: Common Questions

Is it safe to take Lutein with Gemcitabine?
We do not list a known interaction between Lutein and Gemcitabine. 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.
Are Lutein and Gemcitabine 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 Lutein in each. That is a conversation for your prescriber, especially if Gemcitabine is being adjusted to a target.
Does Gemcitabine interact with any supplements?
Yes. Gemcitabine has documented interactions with 39 supplements in our database — Lutein is not one of them. The Gemcitabine interaction page linked on this page lists every one, ranked by severity.
