Ear Drop Days Supply Guide
Ciprodex Days Supply Calculator
This pharmacist-focused guide explains how to calculate Ciprodex days supply using bottle size, estimated drops per mL, dosing frequency, one-ear or both-ears directions, and treatment duration.
This Ciprodex days supply calculator helps pharmacists calculate ear drops days supply using bottle size, drops per mL, and dosing frequency for otic prescriptions.
Basic ear drops days supply formula
Days Supply = Total Drops in Bottle ÷ Drops Used Per Day
To estimate total drops in the bottle, multiply bottle size in mL by your pharmacy's estimated drops per mL standard.
Step-by-step: how to calculate Ciprodex days supply
Step 1: Confirm the bottle size
Confirm the dispensed bottle size. Ciprodex is commonly dispensed as a 7.5 mL otic suspension, but the actual package dispensed should always be verified.
Step 2: Estimate total drops in the bottle
Multiply the bottle size by the estimated drops per mL used in your workflow. Many pharmacies use 20 drops per mL as a working estimate.
Step 3: Determine total daily drops used
Count the total number of drops used each day based on directions for the left ear, right ear, or both ears, and how many times per day the medication is used.
Step 4: Divide total drops by daily use
Divide the total estimated drops in the bottle by the total drops used per day to estimate the mathematical days supply.
Step 5: Apply any duration limit
If the directions specify a fixed course such as 7 days, that may cap the final billed days supply depending on workflow and payer rules.
Use the ear drops days supply calculator
For a faster workflow calculation, use the calculator to estimate days supply using bottle size, left and right ear dosing, frequency, and optional duration caps.
Example Ciprodex days supply calculation
- Bottle size: 7.5 mL
- Estimated drops per mL: 20
- Total estimated drops: 150 drops
- Directions: 4 drops in one ear twice daily
- Total daily use: 8 drops per day
150 ÷ 8 = 18.75 days supply
If the prescription directions also specify use for 7 days, the practical billed days supply may be capped at 7 days.

Frequently asked questions about Ciprodex days supply
How do you calculate Ciprodex days supply?
Estimate the total number of drops in the bottle, then divide by the number of drops used each day based on directions for the left ear, right ear, or both ears.
Why can Ciprodex days supply vary?
Days supply can vary because drop size may differ by bottle design, patient technique can vary, and one-ear versus both-ears directions change total daily use.
Should a 7-day direction cap the billed days supply?
Often yes. If the directions specify a fixed treatment duration such as 7 days, that duration may cap the practical billed days supply depending on workflow and payer requirements.
How many drops are in a 7.5 mL Ciprodex bottle?
A common pharmacy workflow estimate is 20 drops per mL, so a 7.5 mL bottle may be estimated at about 150 drops, although actual drop count can vary.
