Provision as to dispensing of prescriptions

Where a prescription expressly states that it may, subject to the lapse of a specified interval or of specified intervals, be dispensed two or three times, the drug or preparation thereby prescribed may, as the case may be, be supplied a second or a third time after the specified interval or intervals, provided that a prescription shall not for the purposes of these Regulations be taken to authorize the drug or preparation prescribed to be supplied more than once.
