yeah, my doctor has to regularly call up (medicare/the PBS/someone) to have my script generated "on authority" so that I can receive x amount of boxes of something at once (as my dose for that medication falls between two different mg levels of what is produced and boxed).

if this didn't happen, i would have to get two seperate scripts for different strengths of the same medication and be questioned on it every month, or would have to get one box of the lower strength medication, use the whole box and return to the pharmacy every week (and therefore got to the doctors for new repeats every 6 weeks instead of months).

now the second situation might seem unrealistic on the face of it, but imagine if that medication was a pain medication - maybe you're seeing a new-ish doctor and they're weary of prescribing it, or refuse to have it issued on authority to expand your script for whatever reason. it'd be a fucking nightmare
