No Known Interaction
The bottom line No known interaction

Additionally, although there is no interaction, the label for Alectinib Hydrochloride states a food rule worth keeping to.

Rock Rose 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 Rock Rose 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 Rock Rose at all — not against Alectinib Hydrochloride, 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.

Rock Rose overall Use caution Often well tolerated in food-like amounts, but human safety data are limited.

What Alectinib Hydrochloride’s Own FDA Label Lists

This is not an interaction — none of it involves Rock Rose. 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

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. Rock Rose’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Rock Rose side to compare — that is a limit of the record, not a statement that Rock Rose has no side effects.

How to take them

Some Alectinib Hydrochloride Products Have a Food Rule — Rock Rose Should Not Break It

At least one FDA label for a product containing Alectinib Hydrochloride says to take it with food. If you take Rock Rose 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 Rock Rose

What is Rock Rose?

  • Cold and flu-type symptoms
  • Sore throat and mouth health
  • Antimicrobial support
  • Skin care (topical)
  • Emotional 'rescue' / panic in flower remedies

Rock Rose usually refers to plants in the Cistus family, taken as a tea or extract and traditionally used for colds, sore throats, and as an antimicrobial; it is also a Bach flower remedy used for fear and panic. Human evidence is limited and mostly preliminary, so it should not replace proven treatments. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Cistus creticus · Cistaceae · Leaves, flowers, and aerial parts (and a Bach flower remedy made from the flowers) · Tea, liquid extract, capsules, lozenges, essential oil (labdanum/cistus), and Bach flower remedy drops

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

Rock Rose: dosing

There is no established standardized dose for Rock Rose. The right amount depends on the form (tea, extract, lozenge, or capsule) and the strength of the product.The safest approach is to follow the directions on the product label and not exceed them. A pharmacist can help you compare products and decide whether one is appropriate for you. Bach flower remedy versions are taken as a few drops and are very diluted, which is different from herbal Cistus extracts.
