Bifidobacterium Animalis Subsp. Lactis and Miltefosine

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 Miltefosine and Bifidobacterium Animalis Subsp. Lactis 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 Miltefosine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Miltefosine is filed under a single classification — oral drugs. Bifidobacterium Animalis Subsp. Lactis has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Miltefosine’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.

From our pharmacist’s overview on the Miltefosine page

“Miltefosine (Impavido) is one of the few oral medicines that can cure leishmaniasis, a parasitic infection, so the whole job depends on enough drug actually getting into your bloodstream. Every one of the 17 supplement interactions on file targets that exact weak point, absorption from the gut, and this is a list to respect.”
