Lactobacillus Jensenii and Memantine

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 Memantine and Lactobacillus Jensenii 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 Memantine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Memantine is filed under 2 classifications — nmda antagonists, oral drugs. Lactobacillus Jensenii has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Memantine’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

What Lactobacillus Jensenii Itself Has Been Linked To

This is not an interaction — nothing below involves Memantine. It is the side-effect record for Lactobacillus Jensenii on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Lactobacillus Jensenii, 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 Lactobacillus jensenii preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. L. jensenii has been isolated in cases of bacteremia, sepsis, prostate abscess, perinephric abscess, endocarditis, and pulmonary septic emboli.”

Everything above comes from the Natural Medicines adverse-effect record for Lactobacillus Jensenii — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Memantine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Memantine column appears here.

About Lactobacillus Jensenii

What is Lactobacillus Jensenii?

  • Vaginal health
  • Maintaining healthy vaginal flora
  • Bacterial vaginosis support
  • Yeast infection support
  • General probiotic use

Lactobacillus jensenii is one of the natural 'good' bacteria found in a healthy vagina, and it is sometimes added to probiotic products marketed for vaginal health. While its role in the body is well recognized, there is only limited human research on taking it as a supplement, so the benefits are not proven. Talk with your pharmacist or doctor before using it, especially if you have a weakened immune system.

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

Lactobacillus Jensenii: dosing

There is no official or standardized dose for Lactobacillus jensenii. Probiotic amounts are often 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.
