GLP-1 dose schedule calculator
Pick your medication, enter your last dose — see your next 8 dose days.
How this calculator works
It adds your medication’s standard interval — 7 days for weekly injections like Ozempic, Wegovy, Mounjaro, Zepbound and Trulicity; 1 day for Saxenda, Victoza and Rybelsus — to your last dose date. If you’re on a custom or compounded schedule, choose the custom interval. It also shows your medication’s official missed-dose window, summarized in our missed-dose guide.
Or never calculate again
DoseDash tracks your schedule automatically — reminders on dose day, a live countdown, and a medication-level chart in between.
This tool performs date arithmetic only and is not medical advice. Your prescriber’s schedule always takes priority.
