The CDASHIG CM domain contains data relating to concomitant and prior medications used by the subject, such as those given on an as-needed basis or condition-appropriate medications. The same basic data collection variables should be collected for all medications, treatments, and therapies (prior, general concomitant medications, and medications of interest). If additional fields are needed to collect other data about a medication of interest, those should be added as non-standard fields.
Concomitant and prior medications should be coded outside of the CRF collection page.
