Indicates how the medication is to be used by the patient.

When the dose or rate is intended to change over the entire administration period, eg. Tapering dose prescriptions, multiple instances of dosage instructions will need to be supplied to convey the different doses/rates.

Additional instructions such as "Swallow with plenty of water" which may or may not be coded.

The timing schedule for giving the medication to the patient. The Schedule data type allows many different expressions, for example. "Every 8 hours"; "Three times a day"; "1/2 an hour before breakfast for 10 days from 23-Dec 2011:"; "15 Oct 2013, 17 Oct 2013 and 1 Nov 2013".
