The physician orders clindamycin (Cleocin) 75 mg orally four times a day. The child weighs 9 kg. The package insert states the recommended dose should not exceed 25 mg/kg/day. How much should you give in each dose?
25 mg X kg = dose in 24 hours
25 mg X 9 kg = 225 mg in 24 hours
225 divided by 4 doses = 56 mg in each dose
You should give 56 mg every 6 hours or in 4 divided doses.
