Lacticaseibacillus Casei and tislelizumab-jsgr

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 tislelizumab-jsgr and Lacticaseibacillus Casei 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.

What Lacticaseibacillus Casei Itself Has Been Linked To

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

  • Raised blood pressure / A higher chance of infection Worth acting on Additional detail

    “Since Lacticaseibacillus casei preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients.

About Lacticaseibacillus Casei

What is Lacticaseibacillus Casei?

  • Digestive health
  • Diarrhea (including antibiotic-related)
  • Immune support
  • Constipation
  • Gut microbiome balance

Lacticaseibacillus casei (formerly Lactobacillus casei) is a 'friendly' probiotic bacterium found in fermented foods and many supplements. It is most studied for digestive issues like diarrhea, where some evidence is encouraging, but results vary by strain and condition. It is generally well tolerated in healthy people, but those with weakened immune systems should check with a doctor first.
