From the label to the app
| What the label says | What PepLabo does with it |
|---|---|
| Missed dose: give within 4 days (96 hours); if more than 4 days have passed, skip it [1]. | A follow-up arrives 30 minutes after a missed dose time, and Today marks the dose as overdue. PepLabo does not count the days or decide for you. |
| The weekly day can change if at least 3 days (72 hours) pass between two doses [1]. | Today shows your last dose and how long ago it was. You change the weekday in the schedule; whether to move it is your prescriber’s call. |
| A single-dose pen or vial can be stored unrefrigerated at no more than 30 °C for up to 21 days in total [1]. | Enter the expiry date and PepLabo reminds you a week before and on the day. It does not count days since first use or days out of the fridge. |
| Rotate injection sites with each dose [1]. | Each log asks for the site on a front and back body map, and a weekly heat map shows which areas you used. |
