GLP-1 Supply Tracker
Running out of doses mid treatment usually happens for a boring reason: nobody counted ahead. This tracker does the counting. Enter how many doses are in each of your packages, how many packages you have on hand, and the date of your next injection, and it lays out your upcoming weekly dose dates, the date of your last dose from this supply, the day you run out, and a sensible day to reorder by.
How this estimate works
There is no medical model here, just calendar arithmetic on your own numbers. Your total supply is the doses per package multiplied by the packages on hand. Each dose lands 7 days after the one before it, starting from your next injection date. The last dose date is where that weekly sequence runs out.
Two planning dates follow from it. The run out date is the last dose date plus 7 days, the day the following dose would be due with nothing left. The suggested reorder day is the last dose date minus 7 days, which leaves one spare dose in hand while a refill is processed. If that day has already passed, the tracker tells you to order as soon as possible instead of showing a date in the past.
If anything changes, a new package arrives, a dose is missed, or your injection day shifts, run the tracker again with the updated numbers. Every date here depends only on what you actually hold and when your next dose is, so a fresh count is always more useful than an old one.
Frequently asked questions
How far ahead should I reorder my GLP-1 medication?
A common sense buffer is one full dose cycle, which is why this tracker suggests reordering a week before your last dose date, and earlier if your pharmacy or delivery service is slow or has had shortages. Refills can take days to process, and after a long gap prescribers often restart people at a lower dose, so ordering while you still hold at least one or two doses is the safer habit.
What if my dose changes and my packages change too?
Just run the tracker again with the new package size and count. A dose change often means a different package or a different number of doses per package, and the old count stops applying the moment the new package arrives. The dates depend only on the doses you actually hold, not on the dose strength.
What if I miss a week?
Shift everything by a week and run the tracker again with your actual next injection date, because every later date moves with it. What to do about the missed dose itself depends on the medication and how many days have passed. The missed dose sections in the dosage charts explain the label rules for each product, and the dose schedule calculator linked below leads to all of them. When in doubt, ask your pharmacist or prescriber.
