A 6 year old girl attends the Paediatric Assessment Unit with profuse diarrhoea and fever. Her stool microscopy, sensitivity and culture has identified Salmonella enterica which is sensitive to Amoxicillin. The on-call microbiologist has recommended a dose of 30mg/kg, three times a day. She weighs 20kg. The pharmacist advises that Amoxicillin solution is currently available as 250mg/5mL.
How many mL should she be prescribed?
