Masterwort and Ferric Carboxymaltose

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 Ferric Carboxymaltose and Masterwort 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.

What Ferric Carboxymaltose’s Own FDA Label Lists

This is not an interaction — none of it involves Masterwort. These are the most notable effects listed in the ADVERSE REACTIONS section of Ferric Carboxymaltose’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. 7 of them are worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on
  • A severe skin reaction Worth acting on
  • Raised blood pressure Worth acting on
  • Hives Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • An allergic reaction Worth acting on
  • Migraine
  • Dry skin
  • A change in taste

Showing the 10 most notable of 23 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 Ferric Carboxymaltose. Read the label on DailyMed › Where a percentage is shown, it is the share of 1,619 voluntary FDA FAERS reports for Ferric Carboxymaltose that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Masterwort’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Masterwort side to compare — that is a limit of the record, not a statement that Masterwort has no side effects.

About Masterwort

What is Masterwort?

Masterwort
  • Digestive upset
  • Mild anxiety and tension
  • Skin complaints
  • Respiratory and cough relief
  • Traditional tonic

Masterwort (Heracleum sphondylium), a plant in the carrot family, has a long folk-medicine history for digestion, nerves, and skin. Modern scientific evidence to support these uses is very limited, and the plant can cause skin reactions to sunlight, so use it cautiously and talk with your pharmacist or doctor first.

Heracleum sphondylium · Apiaceae · Root, leaves, seeds, and aerial parts · Tea, tincture, dried herb, essential oil

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