Interaction report

Brickellia and Pertuzumab

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 Pertuzumab 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.

What to actually watch for

What Pertuzumab’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 Pertuzumab’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.

Low potassium Worth acting on
Heart failure Worth acting on
A low platelet count Worth acting on
Anemia Worth acting on
Shortness of breath Worth acting on
A severe allergic reaction Worth acting on
A low white blood cell count Worth acting on
Bleeding or bruising Worth acting on
A higher chance of infection Worth acting on
An allergic reaction Worth acting on

Showing the 10 most notable of 38 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 Pertuzumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 30,695 voluntary FDA FAERS reports for Pertuzumab 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.

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.
