Rabdosia Rubescens and Alectinib Hydrochloride

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 Alectinib Hydrochloride and Rabdosia Rubescens 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 Alectinib Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alectinib Hydrochloride is filed under 3 classifications — photosensitizing drugs, hepatotoxic drugs, oral drugs. Rabdosia Rubescens has documented interactions with 3 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate), p-glycoprotein substrates (moderate) and cytochrome p450 2c9 (cyp2c9) substrates (minor) — and none of Alectinib Hydrochloride’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 Alectinib Hydrochloride’s Own FDA Label Lists

This is not an interaction — none of it involves Rabdosia Rubescens. These are the most notable effects listed in the ADVERSE REACTIONS section of Alectinib Hydrochloride’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.

  • Muscle weakness Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • High blood sugar Worth acting on

Showing the 10 most notable of 39 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 Alectinib Hydrochloride. Read the label on DailyMed › Where a percentage is shown, it is the share of 7,249 voluntary FDA FAERS reports for Alectinib Hydrochloride that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Rabdosia Rubescens’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Rabdosia Rubescens side to compare — that is a limit of the record, not a statement that Rabdosia Rubescens has no side effects.

How to take them

Some Alectinib Hydrochloride Products Have a Food Rule — Rabdosia Rubescens Should Not Break It

At least one FDA label for a product containing Alectinib Hydrochloride says to take it with food. If you take Rabdosia Rubescens on an empty stomach out of habit, keep them separate — and take Alectinib Hydrochloride with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Alectinib Hydrochloride products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Administer ALECENSA with food.

From the Dosage and Administration section of the FDA label we read for Alectinib Hydrochloride — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Alectinib Hydrochloride page

“Alectinib (Alecensa) treats ALK-positive lung cancer, and because your liver already has to tolerate this drug, check this page before adding any supplement, not after. Of the 74 ingredients on file, 38 can add stress to the liver, and three of the four major-rated entries (beer, wine, and Siberian cocklebur) are the clearest examples…”

About Rabdosia Rubescens

What is Rabdosia Rubescens?

Rabdosia Rubescens
  • Sore throat and respiratory complaints
  • Inflammation
  • Antimicrobial support
  • Digestive complaints
  • Traditional cancer support

Rabdosia rubescens is a Chinese herb traditionally used for sore throats, inflammation, and infections, and its compound oridonin has drawn lab interest for possible anticancer effects. However, strong human evidence is lacking for any use, and safety has not been well studied, so talk with your pharmacist or doctor before trying it.
