Medication supply calculator
Running out of a medication over a weekend or on vacation is an avoidable problem. This works out your run-out date and a sensible day to request the refill.
Why the lead time matters
Refills fail for boring, predictable reasons, and all of them consume days:
- The prescription has no refills left and the prescriber's office takes 2-3 business days to respond
- The insurance requires a new prior authorization at the start of a plan year
- The pharmacy is out of stock and has to order it
- The refill lands on a holiday weekend
A week of lead time absorbs nearly all of this. For a medication where missing days matters, ask your pharmacy about automatic refills and medication synchronization - most offer both, and syncing everything to one pickup date is one of the better arguments for using a single pharmacy.
The 90-day question
If you refill the same maintenance medication every month, ask your prescriber whether a 90-day supply is appropriate and ask your plan what it costs - 90-day fills are often cheaper per dose, and they cut the number of chances per year for a refill to go wrong from twelve to four.
Tracking what you actually take, including over-the-counter items, is a separate and more important habit - the medication list tracker is the sheet for that.
