Summer Savory 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 Summer Savory 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.

Summer Savory safety at a glance

Summer Savory overall Use caution Likely safe as a food seasoning, but medicinal amounts and the essential oil are not well studied.
Pregnancy Avoid Avoid medicinal amounts during pregnancy because safety has not been established.
Breastfeeding Use caution Food amounts are likely fine, but avoid concentrated supplements due to lack of safety data.

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

How we checked

Why No Interaction Is Listed for Alosetron

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alosetron is filed under 3 classifications — serotonergic drugs, serotonergic drugs, oral drugs. Summer Savory has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Alosetron’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.

“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 Summer Savory

What is Summer Savory?

  • Digestive upset and gas
  • Sore throat and cough
  • Antimicrobial
  • Mild diarrhea
  • Seasoning/culinary use

Summer savory is a common kitchen herb that has long been used as a tea or remedy for digestive complaints and minor infections. Food amounts are generally considered safe, but human studies supporting its medicinal use are very limited, so don't rely on it to treat any health condition. Talk with a pharmacist or doctor before using concentrated extracts or the essential oil.

Satureja hortensis · Lamiaceae · Leaves, flowering tops, and essential oil · Culinary herb (fresh or dried), tea, essential oil, capsules/extracts

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

Summer Savory: dosing

There is no established standardized medicinal dose for summer savory. Most people use it simply as a culinary herb to taste, or as a mild tea made from the dried leaves.If you choose to use a commercial supplement, tea, or essential oil product, follow the directions on the product label and do not exceed them.
