a physcian oreders amoxicillin 250 mg tid, # 300 ml, take until gone. the medication strength is amoxicillin 125 mg/5 ml. how many days will the prescription last/

The duration of treatment with amoxicillin should last for 10 days, according to the prescription.

Explanation:

The duration in days of a treatment with amoxicillin, according to a physician's prescription, depends on the concentration of the medicine and the amount available in the bottle.

Each dose involves administering 10 ml of the drug, so in one day 30 cc will be used.

If the drug has a concentration of 125 mg in 5 ml, 750 mg is equivalent to 30 ml:

125 mg 5 ml

750 mg X

X = (750 mg x 5) / 125

X = 30 ml.

This is the total volume of amoxicillin that can be administered per day.

Dividing the total amount of medicine by the daily volume administered gives the number of days the treatment lasts.

Days of treatment = 300 ml / 30 ml/day = 10 days
