Brickellia and Fosphenytoin Sodium

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 Fosphenytoin Sodium and Brickellia 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 Fosphenytoin Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fosphenytoin Sodium is filed under 12 classifications — including cytochrome p450 2c9 (cyp2c9) inducers, anticonvulsants, cytochrome p450 2c19 (cyp2c19) inducers. Brickellia has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Fosphenytoin Sodium’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 Fosphenytoin Sodium’s Own FDA Label Lists

This is not an interaction — none of it involves Brickellia. These are the most notable effects listed in the ADVERSE REACTIONS section of Fosphenytoin Sodium’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.

  • Seizures Worth acting on mentioned in 12.5% of FDA reports for Fosphenytoin Sodium
  • Loss of vision Worth acting on
  • Hearing loss Worth acting on
  • A bowel blockage Worth acting on
  • Pain or burning when passing urine Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Dehydration Worth acting on
  • Trouble swallowing Worth acting on
  • Trouble passing urine Worth acting on

Showing the 10 most notable of 72 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 Fosphenytoin Sodium. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,553 voluntary FDA FAERS reports for Fosphenytoin Sodium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Brickellia’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Brickellia side to compare — that is a limit of the record, not a statement that Brickellia has no side effects.

From our pharmacist’s overview on the Fosphenytoin Sodium page

“Fosphenytoin sodium (Sesquient) converts to phenytoin in the body, and phenytoin is unforgiving about blood levels. A little too low invites seizures, a little too high brings toxicity.”

About Brickellia

What is Brickellia?

  • Blood sugar support (diabetes)
  • Digestive complaints
  • Gallbladder and bile flow
  • Colds and fever

Brickellia, often sold under names like 'prodigiosa' or as a Mexican folk remedy for diabetes, is a plant in the daisy family traditionally brewed as a tea. Scientific evidence in humans is very limited, so its effectiveness and long-term safety are not well established. Talk with your pharmacist or doctor before using it, especially if you take medicines for blood sugar.

Brickellia grandiflora · Asteraceae · Leaves and flowering tops · Tea (infusion), dried herb, tincture, capsules

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

Brickellia: dosing

There is no established standardized dose for Brickellia. Traditional use is usually as a tea made from the dried leaves and flowering tops, but the strength of homemade preparations varies widely.If you choose to use a commercial product, follow the directions on the label and do not exceed them.
