Drug & supplement interaction

Parsley + Prilocaine, epinephrine

Prilocaine, epinephrine brand name: Citanest Forte.

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 Parsley and Prilocaine, epinephrine 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.

Interaction report

Parsley and Prilocaine, epinephrine

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 Prilocaine, epinephrine and Parsley 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.

How we checked

Why No Interaction Is Listed for Prilocaine, epinephrine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Prilocaine, epinephrine is filed under 2 classifications — anesthesia, alpha-adrenergic agonists. Parsley has documented interactions with 8 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Prilocaine, epinephrine’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 Parsley and Prilocaine, epinephrine May Share Several of the Same Side Effects

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. One of them is worth acting on rather than waiting out — marked below.

Special populations

Parsley in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When used orally in medicinal amounts. Parsley has been used orally as an abortifacient and to stimulate menstrual flow. Population evidence suggests that maternal intake of An-Tai-Yin, an herbal combination product containing parsley and dong quai, during the first trimester increases the risk of congenital malformations of the musculoskeletal system, connective tissue, and eyes.

From our pharmacist’s overview on the Prilocaine, epinephrine page

“Prilocaine with epinephrine (Citanest Forte) is the numbing injection used for dental work and minor procedures, and its short interaction list of six supplements warrants genuine care rather than a shrug.

About Parsley

What is Parsley?

Parsley
  • Water retention and bloating
  • Urinary and bladder support
  • Digestive upset
  • Freshening breath
  • Source of vitamins and antioxidants

Parsley is a popular culinary herb that is safe to eat in normal food amounts and is a good source of vitamins K and C. It is traditionally used as a diuretic and for digestion, but solid human evidence for medicinal benefits is limited. Concentrated supplements, seed extracts, and the essential oil are much stronger than food and should be used cautiously, especially during pregnancy.

Petroselinum crispum · Apiaceae · Leaves, seeds, root, and essential oil · Fresh or dried herb, tea, capsules, extracts, seed oil, essential oil

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

Parsley: dosing

There is no well-established standardized medicinal dose for parsley. Using it as a food or in a cup of parsley tea is the most common and lowest-risk way to take it.If you choose a parsley supplement, follow the directions on the product label and do not exceed the recommended amount. Avoid the concentrated essential oil and high-dose seed products unless guided by a healthcare professional.
