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 Riluzole 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.

Verbena and Riluzole

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 Riluzole 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 Riluzole, 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.
Pregnancy Avoid Traditionally said to affect the uterus, so avoid during pregnancy.
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

What Verbena Itself Has Been Linked To

This is not an interaction — nothing below involves Riluzole. It is the side-effect record for Verbena on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Verbena, this list is the first place to look.

  • A skin rash Additional detail

    “Orally, verbena is well tolerated when used orally in amounts commonly found in foods. When used in medicinal amounts and in combination with other herbs, adverse effects have included gastrointestinal adverse effects and allergic skin reactions.

    Topically, verbena can cause contact dermatitis.”

Everything above comes from the Natural Medicines adverse-effect record for Verbena — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Riluzole’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Riluzole column appears here.

From our pharmacist’s overview on the Riluzole page

“Riluzole (Rilutek, Tiglutik, Exservan) slows the progression of ALS, and it already works the liver hard, which is where this list turns genuinely serious. The four major-rated entries among 141 documented interactions cluster around two hazards: extra liver strain (Siberian cocklebur has caused liver failure, and heavy alcohol from be…”

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.

From our Verbena monograph — the full record covers uses, side effects and every documented interaction.

About Riluzole

What Is Riluzole Used For?

Brand names: Rilutek, Tiglutik, Exservan

Riluzole is approved to treat amyotrophic lateral sclerosis (ALS) — the progressive neurological disease also known as Lou Gehrig's disease. This indication is shared across all available riluzole products, including tablets (Rilutek, riluzole), the dissolving oral film (Exservan), and the oral suspension (Tiglutik).

Tiglutik oral suspension is notable in that it can also be given through a PEG-tube (percutaneous endoscopic gastrostomy tube) for patients who have difficulty swallowing.
