The Math / Science
The Pill Dosage Formula uses the desired dosage amount and amount of the drug on hand to calculate the amount of dosage that should be administered to a patient's IV. The formula for IV Dosage is:
X = D/H * V
Where:
- X = Amount to be administered
- D = Desired dose
- H = Amount of drug on hand
- V = Volume of drug on hand
Example
A doctor prescribes 800 mg of ibuprofen (D). Ibuprofen is available in 200mg tablets (200 / 1 tablet). In this case, the desired dose (D) is 800 mg, the Amount of Drug on hand (H) is 200mg, and Volume (V) is 1 tablet.
X = 800 mg / 200 mg * 1 tablet = 4 tablets
