21 Direction to vary prescribed dose of chemotherapy drug

(1) An authorised prescriber who has written a chemotherapy prescription for a dose of a chemotherapy drug may direct an approved supplier that is to supply the dose on the basis of the prescription to increase or decrease the dose to be supplied, without writing a new prescription, if the new dose is between 90% and 110% of the dose that was originally prescribed. (1A) If the direction is for a new dose of a chemotherapy drug mentioned in section 14A, the amounts of each active ingredient in the new dose must be in the same proportion as the proportion of the active ingredients in the form of a chemotherapy pharmaceutical benefit that has that chemotherapy drug. (2) A new dose directed in accordance with subsections (1) and (1A) that is greater than the maximum amount for the chemotherapy drug determined by section 14 of this instrument does not require approval under section 30 of the Regulations as modified by subsection 18(1) of this instrument. (3) If an approved supplier receives a direction in accordance with subsections (1) and (1A), the supplier must record on the chemotherapy prescription: (a) the new dose of the chemotherapy drug as directed; (b) the name of the authorised prescriber who gave the direction; and (c) the means by which the supplier received the direction (for example, by phone or by fax); and (d) the date and time the supplier received the direction. (4) If an approved supplier records the information mentioned in subsection (3) on a chemotherapy prescription, the prescription is taken to be varied accordingly.
