An undefined dose or duration is not a software error. It means the available evidence is not clear enough for OneChoice to make a formal recommendation for that exact drug, organism, diagnosis, route, or patient group.
Why might the evidence be unclear?
The drug may be used outside an FDA-approved indication, studies may use different regimens, or the available evidence may be limited to small studies, case reports, laboratory (in vitro) activity, or expert opinion. Sometimes a guideline mentions a drug as an option without defining a dose or duration for the specific situation.
Does undefined mean I can choose any regimen?
No. The drug may still have activity, but that does not establish which dose or duration will be safe and effective for the patient.
Review the references in OneChoice Plus along with the patient's organ function, medication list, applicable guidelines, drug labeling, and institutional protocols. An infectious-disease or pharmacy consultation may be helpful when the evidence is limited.
