Veronica and Rolapitant Hydrochloride

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 Rolapitant Hydrochloride and Veronica 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 Veronica at all — not against Rolapitant Hydrochloride, 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 Rolapitant Hydrochloride’s Own FDA Label Lists

This is not an interaction — none of it involves Veronica. These are the most notable effects listed in the ADVERSE REACTIONS section of Rolapitant Hydrochloride’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.

  • Anemia Worth acting on
  • A low white blood cell count Worth acting on
  • A higher chance of infection Worth acting on
  • Mouth irritation or sores
  • Reduced appetite mentioned in 6.1% of FDA reports for Rolapitant Hydrochloride
  • Stomach upset
  • Stomach pain
  • Dizziness

From the ADVERSE REACTIONS section of the FDA label for Rolapitant Hydrochloride. Read the label on DailyMed › Where a percentage is shown, it is the share of 537 voluntary FDA FAERS reports for Rolapitant Hydrochloride that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Veronica’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Veronica side to compare — that is a limit of the record, not a statement that Veronica has no side effects.

From our pharmacist’s overview on the Rolapitant Hydrochloride page

“Most people taking rolapitant (Varubi) are in the middle of chemotherapy, counting on it to keep nausea and vomiting at bay, which is exactly when supplements for immunity, mood, or digestion tend to get added. This list deserves genuine respect.”

About Veronica

What is Veronica?

Veronica
  • Coughs and respiratory complaints
  • Digestive upset and appetite stimulation
  • Gout, arthritis, and rheumatic complaints
  • Kidney and urinary tract conditions
  • Mouth and throat inflammation (topical)

Veronica (speedwell) is a traditional European herb used mainly for coughs, digestive complaints, and joint problems, but there is very little modern scientific evidence to show it actually works for any of these. It is generally considered mild, but its safety has not been well studied, so check with a pharmacist or doctor before using it — and avoid it during pregnancy and breastfeeding.

Veronica officinalis · Plantaginaceae · Above-ground (aerial) parts — the flowering herb, including leaves and stems · Tea (infusion), tincture, dried herb, and topical rinses or gargles

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

Veronica: dosing

There is no standardized or scientifically established dose for Veronica. Traditional use has mostly involved a tea made from the dried herb or a tincture, but exact safe and effective amounts have not been determined by research.If you use a commercial product, follow the directions on the label and do not exceed the recommended amount.
