The usual Augmentin dosage for adults and larger children is one 500-mg tablet every 12 hours or one 250-mg tablet every 8 hours.
Do the math: If its only 20 mg a day for a 72 lb girl she'd have to have 6.66 mg every 8 hours.

mudweiser:
Really quick, if you take 20 mg a day, you should take 6.66 mg every 8 hours.

I'm a little confused... Isn't her total dosage calculated from her weight? :confused:

Calulate the following dosages accordng to kilogram of body weight.
A Physician order Augmentin, 20 mg/kg/day foe Saly Brown who weights 72 pounds. The dose is to be divided and given every 8 hours.What is the total dose? What it is the amount to be given every 8 hours?
If her body weight is 72 pounds,
72\,pounds (\frac {0.45359237\,Kg}{lb})=32.7 \,Kg
32.7\,Kg\,(\frac {20\,mg}{Kg\,day})=654\, \frac {mg}{day} This is the total daily dose
(654\,\frac {mg}{day}) (\frac {1\,day}{3\,doses})=218\,\frac {mg}{dose} This is the dose every 8 hours
In the real world (this is "homework help", after all), pills aren't easily divisible into exact dosages.
In the real world, this is also complicated by this warning:
"Since both the 250-mg and 500-mg tablets of AUGMENTIN contain the same amount of clavulanic acid (125 mg, as the potassium salt), two 250-mg tablets of AUGMENTIN are not equivalent to one 500-mg tablet of AUGMENTIN; therefore, two 250-mg tablets of AUGMENTIN should not be substituted for one 500-mg tablet of AUGMENTIN."
