Agave + Alosetron
Alosetron brand name: Lotronex.
We found no known interaction between Agave and Alosetron 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.
Agave and Alosetron
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 Alosetron and Agave 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 Agave at all — not against Alosetron, 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.

What Alosetron Is Prescribed For, and What Agave Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Alosetron is a prescription medicine with approved uses on its FDA label. Agave is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Alosetron is prescribed for: Alosetron tablets — available as Alosetron, Alosetron Hydrochloride, and Lotronex — are approved only for women with severe diarrhea-predominant irritable bowel syndrome (IBS) whose symptoms have lasted 6 months or longer and who have not gotten adequate relief from conventional therapy. Other causes of GI symptoms must be ruled out first. To qualify as severe, diarrhea-predominant IBS must include diarrhea plus at least one of the following: frequent and severe abdominal pain or discomfort, frequent bowel urgency or fecal incontinence (accidental stool leakage), or significant disruption to daily activities. Clinical studies have not confirmed the same benefit in men.
Agave has been studied for:
-
Constipation studied, not established Agave has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Agave for constipation
Although there has been interest in using oral agave for cancer, there is insufficient reliable information about the clinical effects of agave for this purpose.
-
Diarrhea studied, not established Agave has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Agave for diarrhea
Although there has been interest in using oral agave for diarrhea, there is insufficient reliable information about the clinical effects of agave for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Alosetron on your own; if you are taking Agave for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Alosetron page
“Alosetron (Lotronex) treats severe diarrhea-predominant IBS by acting on serotonin receptors in the gut, and that is where most of its 38 supplement interactions come from. Twenty of the ingredients, 5-HTP among them, raise serotonin on their own, and stacking them on a serotonin-acting drug is a combination I want you to treat with re…”

About Agave
What is Agave?
- Natural sweetener (agave nectar)
- Digestive complaints
- Wound and skin care (topical)
- Mild antimicrobial
- Traditional remedy for inflammation
Agave is a succulent plant best known as the source of agave nectar, a popular sweetener, and the base for tequila and mezcal. While it has a long history of folk use for digestion, skin care, and minor infections, there is very little solid human research to support medicinal benefits, and the raw sap can irritate skin and may be unsafe to take internally in large amounts. Talk to your pharmacist or doctor before using agave as a supplement.
Agave americana · Asparagaceae · Leaves, sap (used to make agave nectar/syrup), and roots · Agave nectar/syrup (sweetener), dried leaf, topical sap preparations, and occasionally capsules or extracts
An interaction check asks whether these two react with each other — it does not ask whether Agave is a good idea for someone in your situation. Here is what our Agave record says about it on its own.
Agave: dosing
There is no established standardized medicinal dose for agave. Most people only encounter it as agave nectar used to sweeten food and drinks, where the "dose" is simply how much sweetener you choose to use.For any supplement product containing agave extract, follow the directions on the product label and do not exceed the recommended amount.
