Estimate when to refill before your medication runs low.
Use the refill calculator to estimate your remaining days of supply, your likely run-out date, and the best time to contact your pharmacy.
Estimate your next refill date in under a minute
Enter your remaining supply and routine. The calculator estimates when you will run out, when to contact the pharmacy, and when to set a reminder.
Your estimated refill window
On trackHow this estimate works: We divide your current supply by your daily use, then move the refill date earlier based on your pharmacy lead time and safety buffer.
Keep refill planning inside the app
MyMedAlert can remind you before your supply gets low so you do not have to calculate this manually every month.
Simple inputs
Start with the supply you have right now instead of digging up an old prescription receipt.
Actionable dates
See your estimated empty date, when to request a refill, and when to set a reminder.
Built for routines
Add a buffer so you still have medication if the pharmacy or prescriber needs extra time.
Common questions about refill timing
- How does the refill calculator work?
- It divides your current supply by how many pills you take each day, then works backward from that run-out date using your pharmacy lead time and preferred safety buffer.
- What if I take half tablets or multiple pills per dose?
- Enter the exact amount you take per dose. For example, use 0.5 for half a tablet or 2 if you take two capsules each time.
- Is this tool a substitute for medical advice?
- No. It is a planning aid only. Always confirm your refill timing and dosage instructions with your pharmacist or prescriber.
Designed for quick answers, not spreadsheet math
Good refill planning comes down to three things: how much you have left, how fast you use it, and how early you need to act.
This tool turns those inputs into dates you can actually use for a reminder, pharmacy call, or download CTA.
Move from one-time calculation to recurring reminders
The calculator helps with today's estimate. MyMedAlert helps you stay ahead next month too, with reminders that can trigger before your supply gets low.
