The bottom line No known interaction

We found no known interaction between Limosilactobacillus Reuteri and Amphetamine 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.

Interaction report

Limosilactobacillus Reuteri and Amphetamine

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 Amphetamine and Limosilactobacillus Reuteri 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 Amphetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amphetamine is filed under 6 classifications — including monoamine oxidase inhibitors (maois), amphetamines, stimulant drugs. Limosilactobacillus Reuteri has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Amphetamine’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.

Keep it in perspective

What to actually watch for

What Limosilactobacillus Reuteri Itself Has Been Linked To

This is not an interaction — nothing below involves Amphetamine. It is the side-effect record for Limosilactobacillus Reuteri on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Limosilactobacillus Reuteri, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

A higher chance of infection Worth acting on Additional detail
“Since Limosilactobacillus reuteri preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. Some lactobacilli species have been isolated in some cases of bacteremia, sepsis, splenic abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis.”

Everything above comes from the Natural Medicines adverse-effect record for Limosilactobacillus Reuteri — expand a row for the licensed statement it rests on. We haven’t matched Amphetamine to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Amphetamine.

Overlapping uses

What Amphetamine Is Prescribed For, and What Limosilactobacillus Reuteri Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Amphetamine is a prescription medicine with approved uses on its FDA label. Limosilactobacillus Reuteri is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Amphetamine is prescribed for: Amphetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older. Adzenys XR-ODT, Dyanavel XR, and the amphetamine extended-release orally disintegrating tablet formulations are specifically approved for ADHD in this age group. Amphetamine Sulfate tablets and Evekeo (amphetamine sulfate tablets) are also approved for narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness) and as a short-term aid in a calorie-restricted weight-loss program for exogenous obesity (weight gain from external factors like overeating) in patients who have not responded to other approaches.

Limosilactobacillus Reuteri has been studied for:

Obesity studied, not established Limosilactobacillus Reuteri has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Limosilactobacillus Reuteri for obesity

Although there has been interest in using oral Limosilactobacillus reuteri for obesity, there is insufficient reliable information about the clinical effects of L. reuteri for this condition.

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 Amphetamine on your own; if you are taking Limosilactobacillus Reuteri 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 Amphetamine page

“Amphetamine (Dyanavel XR, Adzenys ER, Mydayis) is a prescription stimulant, usually taken for ADHD, and its interaction list is one to approach with genuine care. Of the 130 supplements and herbal ingredients on file, 16 carry a major rating, and many of those work the same way, either inhibiting monoamine oxidase, as yohimbe does, or…”

About Limosilactobacillus Reuteri

What is Limosilactobacillus Reuteri?

Infant colic
Diarrhea (including antibiotic-associated)
Digestive health
Oral and gum health
Constipation
Immune support

Limosilactobacillus reuteri (formerly Lactobacillus reuteri) is a probiotic bacterium found in the human gut and certain fermented foods. It has the most supportive evidence for reducing crying in breastfed infants with colic and for some types of diarrhea, while many other uses remain unproven. It is generally well tolerated in healthy people, but people who are very ill or immunocompromised should talk to a doctor first.

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

Taking Limosilactobacillus Reuteri and Amphetamine Together: Common Questions

Is it safe to take Limosilactobacillus Reuteri with Amphetamine?

We do not list a known interaction between Limosilactobacillus Reuteri and Amphetamine. 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.

Are Limosilactobacillus Reuteri and Amphetamine used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Limosilactobacillus Reuteri in each. That is a conversation for your prescriber, especially if Amphetamine is being adjusted to a target.

How was the Limosilactobacillus Reuteri and Amphetamine combination checked?

Interactions in our licensed database are recorded against drug classes. Amphetamine is filed under 6 classifications, and Limosilactobacillus Reuteri has documented interactions with 1 drug class — none of Amphetamine'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 Limosilactobacillus Reuteri interact with any other medications?

Yes. Limosilactobacillus Reuteri has 182 documented drug interactions in our database — Amphetamine 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 Amphetamine interact with any supplements?

Yes. Amphetamine has documented interactions with 130 supplements in our database — Limosilactobacillus Reuteri is not one of them. The Amphetamine interaction page linked on this page lists every one, ranked by severity.
