lb equals 149.43 mcg - 249.05 mcg kg


This ped patient falls in the marked group.

Age Digoxin Dose
(mcg/kg/day)
over 10 y 3 – 5


  • Low dose: `(3 mcg)/(x)` = `(1 Kg)/(49.81 Kg) `

    Therefore `x` = 149.43 mcg



  • High dose: `(5 mcg)/(x)` = `(1 Kg)/(49.81 Kg) `

    Therefore `x` = 249.05 mcg

    Hence the dosage range for digoxin is
    149.43 mcg - 249.05 mcg
