Give 70 milligrams of Lasix® (furosemide) PO now. Pharmacy has sent a package of 20-milligram Lasix tablets. How many tablets will you give? Using the formula:
dose ordered = 70 mg
dose available = 20 mg tablets
|
70
mg |
= 3.5 tablets |
You would give 3 and 1/2 tablets from the package pharmacy sent. Using the calculator, enter 70 as the "Dose ordered" and 20 as the "Dose available per tablet" then click the "Solve" button:

Here's another example. Give 12.5 milligrams of Capoten® (captopril) PO. Pharmacy has sent a 50 milligram Capoten® tablet. How much of the tablet will be given? Using the formula:
dose ordered = 12.5 mg
dose available = 50 mg tablet
|
12.5
mg |
