The bottom line No known interaction

We found no known interaction between Pareira and Futibatinib 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.

Pareira and Futibatinib

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 Futibatinib and Pareira 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 Pareira at all — not against Futibatinib, 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 Futibatinib’s Own FDA Label Lists

This is not an interaction — none of it involves Pareira. These are the most notable effects listed in the ADVERSE REACTIONS section of Futibatinib’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Pain or burning when passing urine Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Chest pain Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on

Showing the 10 most notable of 32 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 Futibatinib. Read the label on DailyMed › Where a percentage is shown, it is the share of 204 voluntary FDA FAERS reports for Futibatinib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Pareira’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Pareira side to compare — that is a limit of the record, not a statement that Pareira has no side effects.

About Pareira

What is Pareira?

  • Urinary tract complaints
  • Bladder irritation and inflammation
  • Kidney stones
  • Fluid retention (diuretic use)
  • Digestive upset

Pareira is a traditional plant remedy, mainly from the South American vine Chondrodendron tomentosum, that has long been used for urinary and bladder complaints. Modern scientific evidence in humans is very limited, and some related plants in this group contain powerful muscle-relaxing compounds, so it should be used cautiously and only under professional guidance.

Chondrodendron tomentosum · Menispermaceae · Root and woody stem (bark) · Dried root, tincture, fluid extract, homeopathic preparations

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

Pareira: dosing

There is no established standardized dose for pareira, and products vary widely in strength and form. Because of this, it is not possible to recommend a specific safe and effective amount.If you choose to use a pareira product, follow the directions on the label and do not exceed the recommended amount.

About Futibatinib

What Is Futibatinib Used For?

Brand name: Lytgobi

Lytgobi (futibatinib) is used to treat adults with intrahepatic cholangiocarcinoma — a cancer that starts inside the bile ducts within the liver — that cannot be surgically removed and has spread locally or to other parts of the body. It is specifically for patients whose cancer has a gene change called an FGFR2 fusion or rearrangement, confirmed by testing, and who have already received prior treatment.

This approval is based on how many patients' tumors responded to Lytgobi and how long those responses lasted. Final confirmation of long-term benefit is still being studied in follow-up clinical trials.

Most-Reported Side Effects for Futibatinib

From FAERS, the FDA’s public side-effect reporting system (204 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 35 reports
Disease progression 31 reports
Hyperphosphataemia 29 reports
Fatigue 26 reports
Dry mouth 24 reports
