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

Lemongrass 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 Lemongrass 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. Lemongrass has documented interactions with 3 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate), glucuronidated drugs (moderate) and pentobarbital (nembutal) (moderate) — 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 Lemongrass. 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

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

How to take them

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

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

What is Lemongrass?

Lemongrass
  • Digestive upset
  • Anxiety and stress
  • Antimicrobial/antifungal
  • Insect repellent
  • Flavoring in food and drinks

Lemongrass is a fragrant tropical grass widely used as a cooking herb, a tea, and an aromatherapy oil. It is generally considered safe in the small amounts used in food, but most of its claimed health benefits come from laboratory or animal studies rather than strong human research. Talk with your pharmacist or doctor before using concentrated supplements or the essential oil, especially if you are pregnant or breastfeeding.

Cymbopogon citratus · Poaceae · Leaves, stalks, and essential oil · Tea, fresh or dried herb, capsules, essential oil, topical preparations

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

Lemongrass: dosing

There is no official standardized dose for lemongrass. The amount used depends on the form, such as tea, capsule, or essential oil.For tea, people commonly steep a small amount of dried or fresh leaves in hot water. For supplements, follow the directions on the product label, since strength varies from brand to brand.

Taking Lemongrass and Alectinib Hydrochloride Together: Common Questions

Is it safe to take Lemongrass with Alectinib Hydrochloride?

If you take Lemongrass on an empty stomach out of habit, keep them separate and take Alectinib Hydrochloride with a meal where the label says to.

Alectinib Hydrochloride is filed under 3 classifications, and Lemongrass has documented interactions with 3 drug classes — none of Alectinib Hydrochloride's classifications are among them.
