Antioxidants + Ramucirumab

Ramucirumab brand name: Cyramza.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Antioxidants and Ramucirumab 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.

Antioxidants and Ramucirumab

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 Ramucirumab and Antioxidants 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 Antioxidants at all — not against Ramucirumab, 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 Ramucirumab’s Own FDA Label Lists

This is not an interaction — none of it involves Antioxidants. These are the most notable effects listed in the ADVERSE REACTIONS section of Ramucirumab’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 bowel blockage Worth acting on
  • Low sodium Worth acting on
  • A low white blood cell count Worth acting on mentioned in 8.5% of FDA reports for Ramucirumab
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • Raised blood pressure Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on

Showing the 10 most notable of 19 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 Ramucirumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,109 voluntary FDA FAERS reports for Ramucirumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Antioxidants’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Antioxidants side to compare — that is a limit of the record, not a statement that Antioxidants has no side effects.

Overlapping uses

What Ramucirumab Is Prescribed For, and What Antioxidants Has Been Studied For

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

Ramucirumab is prescribed for: Cyramza (ramucirumab) injection is used to treat several types of advanced or metastatic cancer in adults. It is used for advanced or metastatic gastric (stomach) cancer or gastro-esophageal junction cancer that has progressed after prior chemotherapy — either alone or combined with paclitaxel. It is also used for metastatic non-small cell lung cancer, either with erlotinib as a first-line treatment for tumors with certain EGFR mutations, or with docetaxel after platinum-based chemotherapy has stopped working. Additionally, Cyramza is used with FOLFIRI chemotherapy for metastatic colorectal cancer that has progressed after certain prior treatments, and as a single agent for hepatocellular carcinoma (a type of liver cancer) in patients who have elevated alpha-fetoprotein levels and have already received sorafenib.

Antioxidants has been studied for:

  • Colorectal cancer studied, not established Antioxidants has been studied for this. Natural Medicines rates the evidence: Possibly Ineffective Read what the research shows

    Antioxidants for colorectal cancer

    Long-term use of the antioxidants selenium or vitamin E does not appear to prevent colorectal cancer.

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

About Antioxidants

What is Antioxidants?

  • General wellness and aging
  • Heart health support
  • Eye health
  • Immune support
  • Skin health

Antioxidants are compounds—like vitamins C and E, selenium, and many plant chemicals—that help protect your cells from a type of damage called oxidative stress. Getting them from a varied diet of fruits and vegetables is clearly healthy, but high-dose antioxidant supplements have shown disappointing or even harmful results in some large studies. For most people, food is the safest and best source.

Capsules, tablets, softgels, powders, and foods (fruits, vegetables, nuts)

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

Antioxidants: dosing

There is no single "antioxidant dose" because the term covers many different nutrients and plant compounds. For vitamins and minerals, established recommended daily amounts and upper limits exist (set by health authorities), and exceeding the upper limit can be unsafe.The best general approach is to get antioxidants from a varied diet rather than pills.

From our Antioxidants monograph — the full record covers uses, side effects and every documented interaction.

Taking Antioxidants and Ramucirumab Together: Common Questions

Are Antioxidants and Ramucirumab 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.
