What is Xifaxan “loe” referring to?
“Xifaxan” is most commonly used online as a misspelling or alternate spelling for Xifaxan/Xifaxan (rifaximin), but “loe” isn’t a standard medical abbreviation for rifaximin based on the information available here. People may be using “loe” to mean things like:
- LOE = Letter of Explanation (used in some billing/coverage contexts)
- LOE = level of evidence (in clinical research)
- LOE = loss of exclusivity (in drug patent/exclusivity discussions)
- A brand name variant or typo connected to a specific document/page
If you meant “LOE” as loss of exclusivity, what does that mean for rifaximin?
If “loe” means loss of exclusivity, the relevant question becomes: when rifaximin’s exclusivity ends, which affects when competing products (often generics) can enter—depending on patent status, regulatory exclusivity, and any litigation.

If you meant “LOE” as a coverage/letter-of-explanation document
Some payers request a Letter of Explanation to justify why a patient needs a drug (or why a certain dose is necessary). In that case, the key details are typically:
- the patient’s diagnosis and severity
- prior treatments tried
- why alternatives are not appropriate
