Drug & supplement interaction

Sassafras + Lanreotide

Lanreotide brand name: Somatuline.

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 Sassafras and Lanreotide 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 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.

Interaction report

Sassafras and Lanreotide

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 Lanreotide and Sassafras 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 Lanreotide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lanreotide is filed under a single classification — cytochrome p450 3a4 (cyp3a4) inhibitors. Sassafras has documented interactions with 2 drug classes — the most serious being cns depressants (moderate) and cytochrome p450 1a2 (cyp1a2) inducers (moderate) — and none of Lanreotide’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 to actually watch for

No Interaction Found — But Data Suggests Sassafras and Lanreotide May Share Several of the Same Side Effects

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. One of them is worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on Additional detail

    Sassafras

    “Sassafras is generally regarded as unsafe for use in medicinal amounts. Any benefits of therapy may not outweigh the risks of toxicity. Orally, sassafras can cause diaphoresis and hot flashes (11). Consumption of large amounts of sassafras oil can cause hallucinations lasting for several days (4).”

From our pharmacist’s overview on the Lanreotide page

“Every supplement on this page interacts with lanreotide (Somatuline) in the same basic way. Lanreotide, injected to treat acromegaly and certain neuroendocrine tumors, can slow CYP3A4, a liver enzyme that many herbal ingredients depend on to be cleared from the body.”

About Sassafras

What is Sassafras?

  • Digestive complaints
  • Cold and flu symptoms
  • Joint and muscle aches
  • Skin conditions (topical folk use)
  • As a flavoring agent (traditional root beer)

Sassafras is an aromatic North American tree whose root bark and oil were once popular in teas and as a flavoring, but it contains safrole, a compound the FDA has banned in foods because it can cause cancer and liver damage. There is no good evidence it safely treats any health condition, and most experts recommend avoiding internal use. If you want the flavor, choose products that are labeled safrole-free.

Sassafras albidum · Lauraceae · Root bark, bark, and essential oil · Tea, dried root bark, essential oil, capsules, and as a flavoring

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

Sassafras: dosing

There is no established safe dose for sassafras, and most experts recommend not taking it internally at all because of safrole. There is no standardized medical dosing.If you use a commercial flavoring product that is labeled safrole-free, follow the directions on the label. Do not use whole sassafras root, bark, or essential oil as a home remedy.

About Lanreotide Injection

What Is Lanreotide Injection Used For?

Brand name: Somatuline

Lanreotide Injection is used for the long-term treatment of acromegaly (a condition where the body produces too much growth hormone) in patients who have not responded adequately to surgery or radiation, or who cannot have those treatments. The goal is to bring growth hormone and IGF-1 levels back to normal.

It is also used to treat adults with unresectable, well- or moderately-differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) to help slow tumor progression, and to treat adults with carcinoid syndrome, where it reduces how often short-acting rescue medications are needed. If a patient is already receiving Lanreotide Injection for GEP-NETs, no additional dose is given for carcinoid syndrome.

Taking Sassafras and Lanreotide Together: Common Questions

Is it safe to take Sassafras with Lanreotide?
We do not list a known interaction between Sassafras and Lanreotide. 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 Sassafras and Lanreotide have any of the same side effects?
Yes — our sources link each of them separately to 4 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.
How was the Sassafras and Lanreotide combination checked?
Interactions in our licensed database are recorded against drug classes. Lanreotide is filed under 1 classification, and Sassafras has documented interactions with 2 drug classes — none of Lanreotide's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Sassafras interact with any other medications?
Yes. Sassafras has 275 documented drug interactions in our database — Lanreotide is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Lanreotide interact with any supplements?
Yes. Lanreotide has documented interactions with 13 supplements in our database — Sassafras is not one of them. The Lanreotide interaction page linked on this page lists every one, ranked by severity.
