How many tablets of famotidine should be administered for a prescribed dose of 40 mg when the tablets are 20 mg each?

To determine the correct number of famotidine tablets to administer, you need to know both the prescribed dose and the strength of each tablet. The prescribed dose is 40 mg, and each tablet contains 20 mg of famotidine.

To calculate the number of tablets required, you can divide the prescribed dose by the strength of each tablet:

40 mg (prescribed dose) ÷ 20 mg (per tablet) = 2 tablets.

This calculation shows that two tablets of famotidine are necessary to achieve the total prescribed dose of 40 mg. This aligns with the answer indicating that 2 tablets should be administered. Understanding this conversion from milligrams to tablet count is essential for accurate medication administration and ensures patient safety.
