How the calculation works

Simple arithmetic — no data is sent anywhere, everything runs in your browser.

1

Days per pack

Pack size ÷ dose frequency = how long one pack lasts. For once-weekly injections, we count each injection as one dose.

2

Current pack runs out

Last dispense date + days per pack.

3

Total supply

Last dispense date + days per pack × (repeats + 1). Includes the pack you're currently using.

4

Organise-by date

Current pack run-out − 7 days (or − 14 days if no repeats remain, to allow time for a GP appointment). This is your action deadline.

Do this once — not every month. Add your medications to MediRemind and get reminded when it's time to act.

Frequently asked questions

Q

How do you calculate when I'll run out of my medication?

A

We divide your pack size by your daily dose equivalent to get how many days each pack lasts. Multiply that by (repeats + 1) to get your total supply in days, then add that to your last dispense date.

Q

Why 7 days notice to organise a repeat?

A

Most pharmacies in Australia can dispense a PBS repeat the same day, but GPs sometimes need to write a new authority script — which can take 1–3 business days, plus you may need an appointment. Seven days gives you a comfortable buffer even during public holidays. For medications with no repeats remaining, we use 14 days to allow time to get a GP appointment and have the new script dispensed.

Q

What if I have 0 repeats left?

A

When you have no repeats remaining, you need a new prescription from your GP before you run out. We use a 14-day buffer (instead of 7) to account for GP appointment wait times. In much of Australia, seeing a GP within a week can be difficult — booking early is important for chronic medications.

Q

Does this work for all medications — PBS and private?

A

Yes. The calculator works for any medication regardless of whether it's PBS-subsidised or private. It uses pack size and dose frequency, so it's suited to tablets, capsules, and regular injections like Ozempic or Wegovy.

Q

Does MediRemind do this automatically?

A

MediRemind calculates reminder dates from the medication and repeat details you enter. After each dispensing, update the remaining repeat count so future reminders stay accurate. You enter your details once — MediRemind handles the scheduling and reminds you before you need to act.

Q

Can I use this for GLP-1 weekly injections like Ozempic or Wegovy?

A

Yes — select 'Once weekly' under 'How often do you take it?' and the calculator adjusts automatically. The pack size field will ask for injections per pen or pack, and we'll calculate your run-out date and organise-by date from there.
