Order: Biaxin 200 mg p.o. q 12 h for a child who weighs 45 lbs.
Have: Biaxin 125 mg per 5 mL
Biaxin label states 15 mg/kg/day in two equal doses.
Is this dosage safe? - correct answer. 1. Convert lbs to kgs. 45lbs = 20.5 kg
2. Calculate the recommended dose per day. A child weighing 20.5 kg can have 307.5
mg PER DAY. So, divide 307.5 by 2 to get a single dose. So, the maximum single dose
is 153.75 mg.
3. NO, the ordered dose is not safe. The doctor ordered 200 mg which is more than
153.75 mg.

, Label: 20 to 40 mg/kg/day in divided doses every 8 hours.
The patient weighs 10 kg. Is this order safe? - correct answer. 1. First, calculate the
minimum and maximum dose per day. The minimum amount would be 200 mg. (20 x
10) The maximum amount would be 400 mg. (40 x 10)
2. Now, since the dose is given every 8 hours, divide the minimum and maximum by 3,
since 3 doses can be given in one day (24 hours). The minimum single dose is 66.7 mg,
and the maximum single dose is 133.3 mg.
3. NO, the ordered dose is not safe. The doctor ordered 200 mg for a single dose which
is more than the maximum allowed single dose of 133.3 mg.
