get_may_treat() is a convenience wrapper for get_medrt() that returns
indications (disease assertions) from MED-RT for RxNorm drugs, when
available. Note that absence of a row (or an empty table altogether)
should not necessarily be interpreted as absence of an indication.
Usage
get_may_treat(
x,
by = c("rxcui", "name"),
keep_input = TRUE,
show_progress = interactive()
)
