Spotted Geranium and Mepolizumab

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 Mepolizumab and Spotted Geranium 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 Spotted Geranium at all — not against Mepolizumab, 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 Mepolizumab’s Own FDA Label Lists

This is not an interaction — none of it involves Spotted Geranium. These are the most notable effects listed in the ADVERSE REACTIONS section of Mepolizumab’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. 3 of them are worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on mentioned in 40.3% of FDA reports for Mepolizumab
  • A higher chance of infection Worth acting on mentioned in 9.4% of FDA reports for Mepolizumab
  • An allergic reaction Worth acting on
  • Cough mentioned in 10.3% of FDA reports for Mepolizumab
  • Sore throat
  • Back pain
  • Joint pain
  • Itching
  • Stomach pain
  • Tiredness

Showing the 10 most notable of 12 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 Mepolizumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 49,399 voluntary FDA FAERS reports for Mepolizumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Spotted Geranium’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Spotted Geranium side to compare — that is a limit of the record, not a statement that Spotted Geranium 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. Spotted Geranium 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 Spotted Geranium reference on this page ↓

About Spotted Geranium

What is Spotted Geranium?

  • Diarrhea
  • Mouth and throat sores
  • Bleeding and wound care
  • Hemorrhoids
  • Sore throat gargle

Spotted Geranium (Geranium maculatum), also called wild geranium or cranesbill, is a North American woodland plant whose tannin-rich root has long been used in folk medicine as an astringent for diarrhea, minor bleeding, and mouth or throat irritation. Modern human studies are very limited, so its effectiveness is largely unproven. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Geranium maculatum · Geraniaceae · Root and rhizome (sometimes the dried leaves) · Dried root, tea, tincture, powder, capsules

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

Spotted Geranium: dosing

There is no established standard dose for Spotted Geranium. Traditional use involved teas, tinctures, and gargles made from the dried root, but amounts varied widely and were not standardized.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

What Is Mepolizumab Injection Used For?

Brand name: Nucala

Nucala is used as an add-on maintenance treatment — meaning it works alongside other medications, not instead of them. It is approved for severe asthma (in patients 6 years and older with high eosinophil levels), chronic rhinosinusitis with nasal polyps (CRSwNP) in adults 18 and older whose symptoms aren't controlled by nasal corticosteroids alone, and COPD in adults with an eosinophilic phenotype whose disease isn't adequately controlled.

Nucala is also approved to treat eosinophilic granulomatosis with polyangiitis (EGPA), a rare form of blood vessel inflammation, and hypereosinophilic syndrome (HES), a condition involving dangerously elevated eosinophil counts, in adults and adolescents 12 and older. It is not meant to relieve sudden asthma attacks or acute COPD flares.
