The bottom line No known interaction

We found no known interaction between Tangerine and Ropinirole 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.

Tangerine and Ropinirole

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 Ropinirole and Tangerine 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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Ropinirole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ropinirole is filed under 5 classifications — including dopamine agonists, cytochrome p450 1a2 (cyp1a2) substrates, cytochrome p450 1a2 (cyp1a2) substrates. Tangerine has documented interactions with 2 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (minor) and midazolam (versed) (minor) — and none of Ropinirole’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

What Tangerine Itself Has Been Linked To

This is not an interaction — nothing below involves Ropinirole. It is the side-effect record for Tangerine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Tangerine, this list is the first place to look.

  • A skin rash Additional detail

    “Orally, very few adverse effects have been reported with the medicinal use of tangerine. However, a thorough evaluation of safety outcomes has not been conducted.

    Topically, contact dermatitis has been associated with tangerine essential oil.”

    “According to one case report, the essential oil of tangerine in a fragrance has been associated with contact dermatitis.”

Everything above comes from the Natural Medicines adverse-effect record for Tangerine — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Ropinirole’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Ropinirole column appears here.

See Every Supplement That Interacts With Ropinirole

This page covers Tangerine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ropinirole page lists 101 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), African Wild Potato (moderate), Ashitaba (moderate) and Ayahuasca (moderate).

By severity: 1 major · 67 moderate · 33 minor.

From our pharmacist’s overview on the Ropinirole page

“Activated charcoal deserves the closest look on this page. It is the only one of the 101 entries rated major against ropinirole (Requip, Adartrel), because charcoal can bind the drug in the gut and shrink the amount that actually reaches you, and for someone relying on ropinirole for Parkinson's disease or restless legs, that can mean…”

About Tangerine

What is Tangerine?

  • Source of vitamin C
  • Digestive support
  • Aromatherapy and relaxation
  • Cough and phlegm (traditional)
  • Skin and flavoring uses

Tangerine is a sweet citrus fruit that is a good source of vitamin C and other nutrients, and is widely enjoyed as food. While the peel and essential oil are used in traditional medicine and aromatherapy, strong human evidence for specific health benefits beyond basic nutrition is limited. Enjoying tangerines as part of a balanced diet is generally safe for most people.

Citrus reticulata · Rutaceae · Fruit, peel, and essential oil · Fresh fruit, juice, dried peel, essential oil, capsules, extracts

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

Tangerine: dosing

There is no official or standardized medicinal dose for tangerine. As a food, you can simply enjoy it the way you would any fruit.For peel, extracts, essential oil, or capsule products, there is no established dose proven safe and effective for any condition. Essential oils are for external or aromatherapy use only unless a professional advises otherwise.

About Ropinirole

What Is Ropinirole Used For?

Brand names: Requip, Adartrel

Ropinirole tablets are used to treat two conditions: Parkinson's disease and moderate-to-severe primary Restless Legs Syndrome (RLS) — the uncomfortable urge to move the legs, especially at night or at rest.

Ropinirole extended-release tablets are indicated specifically for Parkinson's disease only. If you take the extended-release form, it is not approved for RLS — that use applies to the regular (immediate-release) tablets.
