Question

Acetaminophen, in amounts greater than 4 g per day, has been associated with liver toxicity. What is the maximum number of 500-mg tablets of acetaminophen that a person may take daily and not reach the toxic level?

Answer 1

8

Explanation:

Maximum amount of Acetaminophen that can be taken = 4 g per day

Weight of acetaminophen tablet = 500 mg

let the number of tablets that can be taken be 'x'

therefore,

x × 500 mg ≤ 4 g

also, 1 g = 1000 mg

thus,

x × 500 ≤ 4000

or

x ≤ 8

hence,

the maximum numbers of tablets that can be taken per day is 8
