Ox-eye Daisy and Levoleucovorin

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 Levoleucovorin and Ox-eye Daisy 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 Ox-eye Daisy at all — not against Levoleucovorin, 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 Levoleucovorin’s Own FDA Label Lists

This is not an interaction — none of it involves Ox-eye Daisy. These are the most notable effects listed in the ADVERSE REACTIONS section of Levoleucovorin’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. 5 of them are worth acting on rather than waiting out — marked below.

  • A low white blood cell count Worth acting on mentioned in 6.8% of FDA reports for Levoleucovorin
  • Confusion Worth acting on
  • A low platelet count Worth acting on
  • Shortness of breath Worth acting on
  • An allergic reaction Worth acting on
  • Mouth irritation or sores
  • Hair loss
  • Reduced appetite mentioned in 5.0% of FDA reports for Levoleucovorin
  • Stomach upset
  • Itching

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 Levoleucovorin. Read the label on DailyMed › Where a percentage is shown, it is the share of 3,706 voluntary FDA FAERS reports for Levoleucovorin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Ox-eye Daisy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Ox-eye Daisy side to compare — that is a limit of the record, not a statement that Ox-eye Daisy has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Ox-eye Daisy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Ox-eye Daisy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Ox-eye Daisy and Levoleucovorin records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Ox-eye Daisy

What is Ox-eye Daisy?

  • Cough and bronchial complaints
  • Digestive upset
  • Wound healing and skin conditions
  • Mild spasms or cramps
  • As a traditional tonic

Ox-eye daisy is a traditional European folk remedy used for coughs, digestion, and minor skin problems, but there is very little modern scientific research to confirm any of these uses. Because it belongs to the same family as ragweed, it may trigger allergic reactions, and its safety has not been well studied. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Leucanthemum vulgare · Asteraceae · Flowers, leaves, and aerial parts (whole flowering plant) · Tea, dried herb, tincture, topical preparations (lotions, washes)

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

Ox-eye Daisy: dosing

There is no established or standardized dose for ox-eye daisy. Traditional use involved brewing the dried flowers or leaves as a tea, but reliable, research-based dosing guidelines do not exist.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Levoleucovorin Injection

What Is Levoleucovorin Injection Used For?

Brand name: Khapzory

Levoleucovorin injection (brands: Fusilev, Khapzory) is used intravenously in three main situations. First, it is given as a "rescue" treatment after high-dose methotrexate chemotherapy in osteosarcoma (bone cancer) — helping to limit the toxic effects methotrexate can have on healthy cells. Second, it is used when methotrexate is not clearing the body fast enough, or when there has been an accidental overdose of methotrexate or similar drugs called folic acid antagonists.

Third, levoleucovorin injection is used alongside the chemotherapy drug 5-fluorouracil (5-FU) for the palliative treatment of advanced metastatic colorectal cancer — meaning it helps make 5-FU work better, though the goal is disease control rather than cure. It is not approved for pernicious anemia or megaloblastic anemias related to vitamin B12 deficiency.

Most-Reported Side Effects for Levoleucovorin

From FAERS, the FDA’s public side-effect reporting system (3,706 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 288 reports
Neutropenia 251 reports
Diarrhea 246 reports
Decreased appetite 187 reports
Vomiting 171 reports
