Drug & supplement interaction

Verbena + Alectinib Hydrochloride

Alectinib Hydrochloride brand name: Alecensa.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Verbena and Alectinib Hydrochloride in our sources. 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, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Verbena 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 Verbena 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 Verbena 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.

Verbena safety at a glance

Verbena overall Use caution Likely tolerated by many adults in food and tea amounts, but human safety data are limited.

Breastfeeding Avoid Not enough safety information, so avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

No Interaction Found — But Data Suggests Verbena and Alectinib Hydrochloride May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

    Listed in the ADVERSE REACTIONS section of the FDA label for Alectinib Hydrochloride, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Effects for Alectinib Hydrochloride come from the ADVERSE REACTIONS section of its FDA label; effects for Verbena come from the Natural Medicines adverse-effect record, quoted above. 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. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

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

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

What is Verbena?

  • Anxiety and stress
  • Sleep and relaxation
  • Digestive upset
  • Sore throat and oral health
  • Minor inflammation

Verbena (Verbena officinalis), also called vervain, is a traditional herb people use for relaxation, sleep, and minor digestive complaints. Solid human research is limited, so its benefits remain largely unproven. It is best to use cautiously and check with your pharmacist or doctor first, especially if you are pregnant or breastfeeding.

Verbena officinalis · Verbenaceae · Aerial parts (leaves, stems, and flowers) · Tea, tincture, capsules, liquid extract, topical preparations

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

Verbena: dosing

There is no official or standardized dose for verbena. Traditional use most often involves a tea made from the dried herb, but the amount of active compounds can vary widely between products.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Verbena and Alectinib Hydrochloride Together: Common Questions

Is it safe to take Verbena with Alectinib Hydrochloride?
We do not list a known interaction between Verbena and Alectinib Hydrochloride. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Verbena and Alectinib Hydrochloride have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Verbena and Alectinib Hydrochloride at the same time of day?
At least one FDA label for a product containing Alectinib Hydrochloride says to take it with food. If you take Verbena on an empty stomach out of habit, keep them separate and take Alectinib Hydrochloride with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Alectinib Hydrochloride products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Alectinib Hydrochloride interact with any supplements?
Yes. Alectinib Hydrochloride has documented interactions with 74 supplements in our database — Verbena is not one of them. The Alectinib Hydrochloride interaction page linked on this page lists every one, ranked by severity.
