Drug & supplement interaction

Wild Carrot + Niraparib Tosylate

Niraparib Tosylate brand name: Zejula.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Wild Carrot and Niraparib Tosylate in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Wild Carrot and Niraparib Tosylate

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 Niraparib Tosylate and Wild Carrot 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.

Wild Carrot safety at a glance

Wild Carrot overall Use caution Generally used in folk medicine, but human safety data are limited and the seeds may carry more risk.
Pregnancy Likely Unsafe When used orally. The seeds, oil, and above ground parts can cause uterine stimulant, abortifacient, and menstrual stimulant effects. BREAST-FEEDING: Read the full pregnancy detail
Breastfeeding Avoid Not enough safety information is available, so it is best avoided while breastfeeding.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Niraparib Tosylate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Niraparib Tosylate is filed under 2 classifications — p-glycoprotein substrates, oral drugs. Wild Carrot has documented interactions with 4 drug classes — the most serious being antihypertensive drugs (moderate), estrogens (moderate) and lithium (moderate) — and none of Niraparib Tosylate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Wild Carrot and Niraparib Tosylate May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

    Niraparib Tosylate

    Listed in the ADVERSE REACTIONS section of the FDA label for Niraparib Tosylate. Read the label on DailyMed ›

Reported for Wild Carrot but not commonly for Niraparib Tosylate: an allergic reaction and sun sensitivity.

Effects for Niraparib Tosylate come from the ADVERSE REACTIONS section of its FDA label; effects for Wild Carrot come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 51 voluntary FDA FAERS reports for Niraparib Tosylate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Niraparib Tosylate

This page covers Wild Carrot only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Niraparib Tosylate page lists 54 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), St. John's Wort (major), Bitter Melon (moderate), Black Pepper (moderate) and Bulbine Natalensis (moderate).

From our pharmacist’s overview on the Niraparib Tosylate page

“Activated charcoal, popular for bloating and so-called detox routines, can trap niraparib (Zejula) in the gut before it absorbs, and St. John's wort can drive levels of the drug down another way.”

About Wild Carrot

What is Wild Carrot?

Wild Carrot
  • Urinary and bladder complaints
  • Digestive upset and gas
  • Menstrual support
  • Supporting milk production
  • Mild diuretic (water pill) effect

Wild carrot is a traditional herb (the wild ancestor of the garden carrot) used mostly for urinary, digestive, and menstrual complaints. High-quality human studies are lacking, so its benefits are unproven, and it should be avoided in pregnancy because of traditional use to affect the uterus. Talk with your pharmacist or doctor before using it.

Daucus carota · Apiaceae · Seeds, root, leaves, and flowers; sometimes the essential oil · Tea, dried herb, tincture, capsules, seed extract, essential oil

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

Wild Carrot: dosing

There is no well-established, standardized dose for wild carrot. Traditional preparations vary widely, and the strength of teas, tinctures, capsules, and seed extracts is not consistent between products.If you choose to use a wild carrot product, follow the directions on the label and do not exceed the recommended amount. Because quality and potency can differ, choose products from reputable brands.

About Niraparib

What Is Niraparib Used For?

Brand name: Zejula

Zejula is used as maintenance therapy — meaning it is taken after chemotherapy to help keep the cancer from coming back — for adults with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer. For first-line maintenance, Zejula is approved for patients whose cancer is HRD-positive (has certain DNA-repair defects, including BRCA mutations or genomic instability) and who have responded to their first round of platinum-based chemotherapy.

Zejula is also approved for maintenance treatment in adults with recurrent ovarian, fallopian tube, or primary peritoneal cancer that carries a germline BRCA mutation (an inherited change in the BRCA gene), when the cancer has responded to platinum-based chemotherapy. In both cases, a companion diagnostic test is required to confirm eligibility before starting Zejula.

Niraparib Tosylate is filed under 2 classifications, and Wild Carrot has documented interactions with 4 drug classes — none of Niraparib Tosylate's classifications are among them.
