National AHA $1 days-supply pocket card — tablets, liquids, insulin, inhalers, eye drops, and weekly GLP-1 math. Not a state-board product.
A national Allied Health Academy pocket card for tablets, liquids, insulin, inhalers, eye drops, and weekly GLP-1 math. Not a state-board product. Use the free day supply calculators first, then keep the card at the bench.
For educational purposes only — consult the pharmacist or prescriber. This tool computes days supply from the quantity and directions you enter. It does not recommend doses, diagnose, or determine insurance eligibility.
Divide the total quantity dispensed by the amount the patient uses per day. The hard part is converting the sig into a daily amount first: milliliters per day, puffs per day, drops per day, units per day, or grams per day.
Yes. Every Allied Health Academy pharmacy tool is free to use, with no account required, and shows the step-by-step math so you can check your own work.
These calculators are free. If you are studying for the PTCB exam, we also publish paid study products and a PharmD-led certification program. Founders pricing is $499 through December 2026.
