Interval Period

Important: You’ll receive email updates from us showing your current interval period for each product and if your repeat prescription is available.


The interval period is the set amount of time your prescriber or pharmacy requires between dispensing one supply of your medication and the next.


Interval Period Table


How it works in practice

  • If your doctor prescribes 30g of dried herb with a monthly repeat, your pharmacy may set the interval at 28–31 days.

  • If you try to fill a repeat earlier than your interval allows, the pharmacy system will show it as too soon and you’ll need to wait until the next eligible date.

Key points for patients Patient information

  • Your monthly limit and interval period are related but not the same:
  • Monthly limit = how much you can get in total per month.
  • Interval period = how soon you can get the next refill.
  • You’ll be emailed your next eligible refill date.
  • If your usage changes, speak with your doctor to adjust.
