Lobelia + Telotristat Etiprate
Telotristat Etiprate brand name: Xermelo.
We found no known interaction between Lobelia and Telotristat Etiprate 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 Telotristat Etiprate 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.
Lobelia and Telotristat Etiprate
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 Telotristat Etiprate and Lobelia 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.
Lobelia safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Telotristat Etiprate
Interactions in our licensed database are recorded against drug classes, not just single drug names. Telotristat Etiprate is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) inducers, oral drugs. Lobelia has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Telotristat Etiprate’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.
Lobelia Does Interact With Other Medications
Lobelia has 1 moderate known drug interaction in our database — Telotristat Etiprate isn’t one of them. If you take anything else, check it against the full list below.

Some Telotristat Etiprate Products Have a Food Rule — Lobelia Should Not Break It
At least one FDA label for a product containing Telotristat Etiprate says to take it with food. If you take Lobelia on an empty stomach out of habit, keep them separate — and take Telotristat Etiprate 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 Telotristat Etiprate 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.
Administration Take Xermelo with food [see Clinical Pharmacology ( 12.3 ), Clinical Studies ( 14 )] .

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 Telotristat Etiprate page
“Telotristat etiprate (Xermelo) works in the gut to calm the severe diarrhea of carcinoid syndrome, and the lone major-rated interaction among its 36 flagged supplements strikes at that point. Activated charcoal can soak up the drug before it reaches the bloodstream, and 17 of the entries, mostly bulking fibers and charcoal products, ca…”

About Lobelia
What is Lobelia?
- Asthma and breathing problems
- Cough and bronchitis
- Smoking cessation aid
- Muscle relaxation
Lobelia is a traditional herb once used for breathing problems and to help people quit smoking, but reliable evidence supporting these uses is lacking. It can be toxic in higher amounts, causing serious side effects, so it should be used with great caution and only under professional guidance.
Lobelia inflata · Campanulaceae · Dried aerial parts (leaves, stems, flowers, and seeds) · Capsules, tinctures, liquid extracts, teas, and dried herb
An interaction check asks whether these two react with each other — it does not ask whether Lobelia is a good idea for someone in your situation. Here is what our Lobelia record says about it on its own.
Lobelia: dosing
There is no well-established or standardized safe dose of lobelia. Because the plant can be toxic, the amount that helps and the amount that harms may be close together.If a product is used, follow the directions on the label carefully and do not exceed them. We do not recommend self-dosing this herb without professional guidance.

About Telotristat
What Is Telotristat Used For?
Brand name: Xermelo
Xermelo (telotristat) tablets are approved to treat carcinoid syndrome diarrhea in adults. Carcinoid syndrome is a set of symptoms caused by certain tumors — called neuroendocrine tumors — that release excess serotonin into the body, triggering frequent, often severe diarrhea.
Xermelo is used in combination with somatostatin analog (SSA) therapy — a class of injected medications commonly used to control carcinoid syndrome — in patients whose diarrhea is still not adequately controlled by SSA therapy alone.
