Drug & supplement interaction

Lactobacillus Gasseri + Dexlansoprazole

Dexlansoprazole brand name: Dexilant Solutab.

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 Lactobacillus Gasseri and Dexlansoprazole 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

Lactobacillus Gasseri and Dexlansoprazole

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 Dexlansoprazole and Lactobacillus Gasseri 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.

Lactobacillus Gass... overall Use caution Generally well tolerated in healthy adults, but evidence is limited and some people should avoid it.

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

How we checked

Why No Interaction Is Listed for Dexlansoprazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dexlansoprazole is filed under 5 classifications — including proton pump inhibitors (ppis), cytochrome p450 1a2 (cyp1a2) inducers, cytochrome p450 2c19 (cyp2c19) substrates. Lactobacillus Gasseri has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Dexlansoprazole’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 Lactobacillus Gasseri and Dexlansoprazole May Share a Side Effect

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.

  • A higher chance of infection Worth acting on Additional detail

    Lactobacillus Gasseri

    “Since Lactobacillus gasseri 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 cases of bacteremia, sepsis, splenic abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis.”

About Lactobacillus Gasseri

What is Lactobacillus Gasseri?

  • Digestive health
  • Weight and belly fat management
  • Vaginal and urinary health
  • Bloating and gut discomfort
  • General immune support

Lactobacillus gasseri is a 'friendly' probiotic bacterium found naturally in the human gut, mouth, and vaginal tract, and in some fermented foods. Early research suggests it may help with digestion, weight management, and vaginal health, but the evidence is limited and far from conclusive. It is generally well tolerated in healthy people, but anyone who is pregnant, breastfeeding, or has a weakened immune system should talk to a pharmacist or doctor first.

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

Lactobacillus Gasseri: dosing

There is no official standardized dose of L. gasseri. Probiotic amounts are usually measured in colony-forming units (CFUs), and products vary widely.The best approach is to follow the directions on the product label and not exceed the recommended amount.

About Dexlansoprazole

What Is Dexlansoprazole Used For?

Brand name: Dexilant Solutab

Dexlansoprazole delayed-release capsules — sold as Dexilant and available as a generic — are used in patients 12 years of age and older to heal erosive esophagitis (EE), which is damage to the esophagus caused by stomach acid. They are also used to keep that damage healed and relieve heartburn over time.

In addition, dexlansoprazole treats heartburn from non-erosive gastroesophageal reflux disease (GERD) — that is, acid reflux that causes symptoms without visible damage to the esophagus. Both Dexilant and generic dexlansoprazole delayed-release capsules share these same approved uses.

Taking Lactobacillus Gasseri and Dexlansoprazole Together: Common Questions

Is it safe to take Lactobacillus Gasseri with Dexlansoprazole?
We do not list a known interaction between Lactobacillus Gasseri and Dexlansoprazole. 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 Lactobacillus Gasseri and Dexlansoprazole have any of the same side effects?
Yes — our sources link each of them separately to one 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 Lactobacillus Gasseri and Dexlansoprazole combination checked?
Interactions in our licensed database are recorded against drug classes. Dexlansoprazole is filed under 5 classifications, and Lactobacillus Gasseri has documented interactions with 1 drug class — none of Dexlansoprazole'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 Lactobacillus Gasseri interact with any other medications?
Yes. Lactobacillus Gasseri has 182 documented drug interactions in our database — Dexlansoprazole 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 Dexlansoprazole interact with any supplements?
Yes. Dexlansoprazole has documented interactions with 153 supplements in our database — Lactobacillus Gasseri is not one of them. The Dexlansoprazole interaction page linked on this page lists every one, ranked by severity.
