Figwort and Opicapone

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 Opicapone and Figwort 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 Opicapone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Opicapone is filed under 3 classifications — dopamine agonists, p-glycoprotein substrates, oral drugs. Figwort has documented interactions with 2 drug classes — the most serious being diuretic drugs (moderate) and lithium (moderate) — and none of Opicapone’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 Opicapone’s Own FDA Label Lists

This is not an interaction — none of it involves Figwort. These are the most notable effects listed in the ADVERSE REACTIONS section of Opicapone’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Hallucinations Worth acting on mentioned in 13.9% of FDA reports for Opicapone
  • Fainting Worth acting on
  • Confusion Worth acting on
  • Raised blood pressure Worth acting on
  • Weight gain
  • Weight loss
  • Dry mouth
  • Low blood pressure
  • Drowsiness
  • Trouble sleeping

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 Opicapone. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,261 voluntary FDA FAERS reports for Opicapone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Figwort’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Figwort side to compare — that is a limit of the record, not a statement that Figwort has no side effects.

About Figwort

What is Figwort?

  • Skin conditions like eczema and psoriasis
  • Minor wounds and rashes
  • Swelling and inflammation
  • Mild constipation
  • Traditional 'detox' or lymphatic support

Figwort is a traditional herb used mainly for skin problems and minor swelling, but solid human studies are lacking, so its benefits remain unproven. It is generally used short-term and topically, and people with heart conditions, pregnant women, and nursing mothers should avoid it until more is known.

Scrophularia nodosa · Scrophulariaceae · Aerial parts (leaves, stems, flowers) and sometimes the root · Tea, tincture, capsules, dried herb, topical creams or ointments

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

Figwort: dosing

There is no established standardized dose for figwort. Traditional use varies by the form (tea, tincture, capsule, or ointment) and by the product maker. Avoid using more than the label suggests, and do not use it for long periods without professional advice.

From our Figwort monograph — the full record covers uses, side effects and every documented interaction.

About Opicapone

What Is Opicapone Used For?

Brand name: Ongentys

Ongentys (opicapone) is used alongside levodopa/carbidopa to treat Parkinson's disease in adults who experience 'off' episodes — periods when medication wears off and Parkinson's symptoms return before the next dose is due.

It is not used alone. Ongentys works as an add-on to help levodopa stay active longer, reducing the time patients spend in these 'off' states.

Most-Reported Side Effects for Opicapone

From FAERS, the FDA’s public side-effect reporting system (2,261 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hallucination 314 reports
Dyskinesia 306 reports
Fall 258 reports
On and off phenomenon 158 reports
Tremor 143 reports
