Prescription Refill Date Calculator
Running out of medicine on a weekend or holiday is stressful — and avoidable. This free tool calculates the exact date your tablets will finish from your count and daily dose, and sets a refill reminder date so you reorder in time.
How many tablets are in the pack or box.
How many you take per day (e.g. morning-evening = 2).
How many days before it runs out you want to refill.
This is only an estimate, not medical advice. Always take medicine as your doctor says.
How to use
- Enter how many tablets you have and how many you take per day.
- Pick the date you started this pack and how many days early you want the refill reminder.
- Click Calculate Refill Date — you will see the finish date, the refill-by date, and days left.
Tips
- Set the reminder a week before you run out — pharmacies can take days to process a refill.
- Count a small safety margin in; missing a day of some medicines matters more than others.
- Ask your doctor how many days early you may collect — rules differ by medicine.
