Refill dates are estimates. Verify payer rules, claim history, overrides, and adjudication.
Fridge Shipment Check
Checks New Year’s Day, Martin Luther King Jr. Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas Day.
Injection Day Supply
Injection day supply is a workflow estimate. Verify package size and directions.

Examples: GLP-1s, Ajovy, Repatha, biologics, and other maintenance injectables. For frequency-based day supply math only. Verify package and directions.
Oral Medications
Calculate standard tablet/capsule, liquid, quantity needed, titration, taper, and patterned day supply.
Reverse day supply math. Use this when you know the dose and target days supply and need the quantity to dispense.
For staged schedules where each step has its own dose and duration. Enter dose as total units per day. To calculate the final step until gone, enter Written Quantity, check the option below, and PharmCalc will auto-calculate the final step days.
For uneven weekly tablet/capsule schedules. Example: take 1 tablet daily and may take 1 additional tablet Monday, Wednesday, and Friday.
Day supply calculations are for workflow support. Verify directions, quantity, and rounding policy.

Adherence & Utilization
Investigate refill timing, days elapsed, estimated remaining medication, and average daily use.
Count days between dates or add/subtract days from a start date. Useful for RTS checks, fill timing, adherence review, shipment timing, and quick workflow date math.
Use this for “how many days has it been since?” checks.
Estimates how much medication a patient should have left based on quantity, daily dose, and last fill date.
Leave As Of Date blank to use today.
Determine the average daily utilization represented by a quantity and days supply.
Calculate a short-fill plan to help line one medication up with a target sync date. Repeat for each medication the patient wants synced.
Leave As Of Date blank to use today. This estimates the bridge quantity needed from the as-of date to the target sync date.

Insulin
Insulin results are estimates. Verify package size and your pharmacy's priming and waste policy.

Eye & Ear Medications
For staged drop schedules. Enter each active step; leave unused steps hidden unless the SIG needs them.
Drop math is an estimate. Confirm drops/mL, treated eye/ear count, taper stages, package quantity, and pharmacist guidance before using.
Recent Calculations
Inhalers & Nasal Sprays
Inhaler and spray results depend on actuation counts and daily use. Verify package labeling. SMART therapy day supply should use the documented or pharmacist-approved maximum total daily puffs.

Topical Medications
Topical day supply can be audit-sensitive. Use policy-approved estimates.
Use daily amount for traditional topical estimates, weekly amount for products directed by week, or pump count for metered topical pumps such as testosterone gel.
Topicals can be audit-sensitive.
Reference estimates:
FTU ≈ 0.5 g • Pea-sized ≈ 0.25 g
Examples:
• 30 g testosterone gel
• 42.5 g estradiol cream
• 60 g triamcinolone ointment
• 100 g ketoconazole cream
