Indicates how the timing of this dosage instruction relates to the preceding dosage instruction. Specifically, is it concurrent (AND) or sequential (THEN).

Conformance Rule: As this will establish the relationship to the previous dosage lines (example: first and second dosage line, the second and thrid dosage line, etc.) this must be present for all dosage lines except for the FIRST dosage line.

Usage Note: ANDs are instructions lines that are done together and THENs are instructions that are sequential and are done following the previous line. ANDs and THENs can be used individually or mixed together depending on the specific instructions.

Example using just AND: Take 1 tablet every morning and 2 tablets every evening.

Example using just THEN: Take 1 tablet every morning for 1 week THEN take 2 tablets every morning for 1 week.

Example using both: Take 1 tablet every morning AND 2 tablets every evening for 1 week THEN take 2 tablets every morning AND 3 tablets every evening for 1 week.
