Pulse Diagnosis and Leucovorin Calcium

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 Leucovorin Calcium and Pulse Diagnosis 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 Pulse Diagnosis at all — not against Leucovorin Calcium, 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 to actually watch for

What Leucovorin Calcium’s Own FDA Label Lists

This is not an interaction — none of it involves Pulse Diagnosis. These are the most notable effects listed in the ADVERSE REACTIONS section of Leucovorin Calcium’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 5.8% of FDA reports for Leucovorin Calcium
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Hives Worth acting on
  • A higher chance of infection Worth acting on
  • Mouth irritation or sores
  • Hair loss
  • Reduced appetite
  • Constipation
  • Diarrhea mentioned in 9.5% of FDA reports for Leucovorin Calcium

Showing the 10 most notable of 14 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 Leucovorin Calcium. Read the label on DailyMed › Where a percentage is shown, it is the share of 19,003 voluntary FDA FAERS reports for Leucovorin Calcium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Pulse Diagnosis’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Pulse Diagnosis side to compare — that is a limit of the record, not a statement that Pulse Diagnosis 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. Pulse Diagnosis 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 Pulse Diagnosis reference on this page ↓

  • 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 Pulse Diagnosis

What is Pulse Diagnosis?

  • Traditional Chinese Medicine assessment
  • Ayurvedic health evaluation
  • Assessing overall body balance or 'energy'
  • Guiding herbal or lifestyle recommendations

Pulse diagnosis is a traditional diagnostic technique used in systems like Traditional Chinese Medicine and Ayurveda, not a herb or dietary supplement. It involves a practitioner feeling the pulse at the wrist to assess health, but it has not been shown to be a reliable or reproducible way to diagnose disease, and it should never replace standard medical testing.

Diagnostic technique (not a supplement or product)

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

Pulse Diagnosis: dosing

There is no dose for pulse diagnosis because it is a diagnostic technique, not a substance you take. There is nothing to measure in milligrams, capsules, or drops.If a practitioner recommends specific herbs or supplements based on pulse diagnosis, treat those products with the same caution you would any supplement.

About Leucovorin

What Is Leucovorin Used For?

Brand name: Wellcovorin

Leucovorin is used to reduce the harmful effects of methotrexate when the body is slow to clear it, and to counteract accidental overdoses of drugs that block folic acid (called folic acid antagonists or DHFR inhibitors). It is also used to treat cerebral folate transport deficiency (FOLR1-CFTD), a rare genetic condition that prevents the brain from receiving enough folate.

The injectable forms — including leucovorin calcium injection and Vykoura — are additionally approved for rescue after high-dose methotrexate therapy, for treatment of megaloblastic anemia (a type of anemia caused by low folic acid) when oral treatment isn't possible, and for use alongside fluorouracil in treating metastatic colorectal cancer. Leucovorin calcium injection is specifically indicated for rescue after high-dose methotrexate in osteosarcoma.

Most-Reported Side Effects for Leucovorin Calcium

From FAERS, the FDA’s public side-effect reporting system (19,003 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 1,799 reports
Nausea 1,388 reports
Vomiting 1,135 reports
Neutropenia 1,094 reports
Fever 1,011 reports
